`pygame.``Surface`
  pygame object for representing images
  Surface((width, height), flags=0, depth=0, masks=None) -> Surface
  Surface((width, height), flags=0, Surface) -> Surface

  A pygame Surface is used to represent any image. The Surface has a fixed resolution and pixel format. Surfaces with 8-bit pixels use a color palette to map to 24-bit color.

  Call `pygame.Surface()`pygame object for representing images to create a new image object. The Surface will be cleared to all black. The only required arguments are the sizes. With no additional arguments, the Surface will be created in a format that best matches the display Surface.

  The pixel format can be controlled by passing the bit depth or an existing Surface. The flags argument is a bitmask of additional features for the surface. You can pass any combination of these flags:

      HWSURFACE    creates the image in video memory
      SRCALPHA     the pixel format will include a per-pixel alpha

  Both flags are only a request, and may not be possible for all displays and formats.

  Advance users can combine a set of bitmasks with a depth value. The masks are a set of 4 integers representing which bits in a pixel will represent each color. Normal Surfaces should not require the masks argument.

  Surfaces can have many extra attributes like alpha planes, colorkeys, source rectangle clipping. These functions mainly effect how the Surface is blitted to other Surfaces. The blit routines will attempt to use hardware acceleration when possible, otherwise they will use highly optimized software blitting methods.

  There are three types of transparency supported in pygame: colorkeys, surface alphas, and pixel alphas. Surface alphas can be mixed with colorkeys, but an image with per pixel alphas cannot use the other modes. Colorkey transparency makes a single color value transparent. Any pixels matching the colorkey will not be drawn. The surface alpha value is a single value that changes the transparency for the entire image. A surface alpha of 255 is opaque, and a value of 0 is completely transparent.

  Per pixel alphas are different because they store a transparency value for every pixel. This allows for the most precise transparency effects, but it also the slowest. Per pixel alphas cannot be mixed with surface alpha and colorkeys.

  There is support for pixel access for the Surfaces. Pixel access on hardware surfaces is slow and not recommended. Pixels can be accessed using the `get_at()` and `set_at()` functions. These methods are fine for simple access, but will be considerably slow when doing of pixel work with them. If you plan on doing a lot of pixel level work, it is recommended to use a `pygame.PixelArray` pygame object for direct pixel access of surfaces, which gives an array like view of the surface. For involved mathematical manipulations try the `pygame.surfarray` pygame module for accessing surface pixel data using array interfaces module (It's quite quick, but requires NumPy.)

  Any functions that directly access a surface's pixel data will need that surface to be lock()'ed. These functions can `lock()` and `unlock()` the surfaces themselves without assistance. But, if a function will be called many times, there will be a lot of overhead for multiple locking and unlocking of the surface. It is best to lock the surface manually before making the function call many times, and then unlocking when you are finished. All functions that need a locked surface will say so in their docs. Remember to leave the Surface locked only while necessary.

  Surface pixels are stored internally as a single number that has all the colors encoded into it. Use the `map_rgb()` and `unmap_rgb()` to convert between individual red, green, and blue values into a packed integer for that Surface.

  Surfaces can also reference sections of other Surfaces. These are created with the `subsurface()` method. Any change to either Surface will effect the other.

  Each Surface contains a clipping area. By default the clip area covers the entire Surface. If it is changed, all drawing operations will only effect the smaller area.

  `blit`()
    draw one image onto another
    blit(source, dest, area=None, special_flags=0) -> Rect

    Draws a source Surface onto this Surface. The draw can be positioned with the dest argument. Dest can either be pair of coordinates representing the upper left corner of the source. A Rect can also be passed as the destination and the topleft corner of the rectangle will be used as the position for the blit. The size of the destination rectangle does not effect the blit.

    An optional area rectangle can be passed as well. This represents a smaller portion of the source Surface to draw.

    New in version 1.8: Optional `special_flags`: `BLEND_ADD`, `BLEND_SUB`, `BLEND_MULT`, `BLEND_MIN`, `BLEND_MAX`.

    New in version 1.8.1: Optional `special_flags`: `BLEND_RGBA_ADD`, `BLEND_RGBA_SUB`, `BLEND_RGBA_MULT`, `BLEND_RGBA_MIN`, `BLEND_RGBA_MAX` `BLEND_RGB_ADD`, `BLEND_RGB_SUB`, `BLEND_RGB_MULT`, `BLEND_RGB_MIN`, `BLEND_RGB_MAX`.

    The return rectangle is the area of the affected pixels, excluding any pixels outside the destination Surface, or outside the clipping area.

    Pixel alphas will be ignored when blitting to an 8 bit Surface.

    For a surface with colorkey or blanket alpha, a blit to self may give slightly different colors than a non self-blit.

  `blits`()
    draw many images onto another
    blits(blit_sequence=(source, dest), ...), doreturn=1) -> [Rect, ...] or None
    blits((source, dest, area), ...)) -> [Rect, ...]
    blits((source, dest, area, special_flags), ...)) -> [Rect, ...]

    Draws many surfaces onto this Surface. It takes a sequence as input, with each of the elements corresponding to the ones of `blit()`. It needs at minimum a sequence of (source, dest).

    Parameters

      - blit_sequence -- a sequence of surfaces and arguments to blit them, they correspond to the `blit()` arguments

      - doreturn -- if `True`, return a list of rects of the areas changed, otherwise return `None`

    Returns

      a list of rects of the areas changed if `doreturn` is `True`, otherwise `None`

    Return type

      list or None

    New in pygame 1.9.4.

  `convert`()
    change the pixel format of an image
    convert(Surface=None) -> Surface
    convert(depth, flags=0) -> Surface
    convert(masks, flags=0) -> Surface

    Creates a new copy of the Surface with the pixel format changed. The new pixel format can be determined from another existing Surface. Otherwise depth, flags, and masks arguments can be used, similar to the `pygame.Surface()`pygame object for representing images call.

    If no arguments are passed the new Surface will have the same pixel format as the display Surface. This is always the fastest format for blitting. It is a good idea to convert all Surfaces before they are blitted many times.

    The converted Surface will have no pixel alphas. They will be stripped if the original had them. See `convert_alpha()` for preserving or creating per-pixel alphas.

    The new copy will have the same class as the copied surface. This lets as Surface subclass inherit this method without the need to override, unless subclass specific instance attributes also need copying.

  `convert_alpha`()
    change the pixel format of an image including per pixel alphas
    convert_alpha(Surface) -> Surface
    convert_alpha() -> Surface

    Creates a new copy of the surface with the desired pixel format. The new surface will be in a format suited for quick blitting to the given format with per pixel alpha. If no surface is given, the new surface will be optimized for blitting to the current display.

    Unlike the `convert()` method, the pixel format for the new image will not be exactly the same as the requested source, but it will be optimized for fast alpha blitting to the destination.

    As with `convert()` the returned surface has the same class as the converted surface.

  `copy`()
    create a new copy of a Surface
    copy() -> Surface

    Makes a duplicate copy of a Surface. The new surface will have the same pixel formats, color palettes, transparency settings, and class as the original. If a Surface subclass also needs to copy any instance specific attributes then it should override `copy()`.

  `fill`()
    fill Surface with a solid color
    fill(color, rect=None, special_flags=0) -> Rect

    Fill the Surface with a solid color. If no rect argument is given the entire Surface will be filled. The rect argument will limit the fill to a specific area. The fill will also be contained by the Surface clip area.

    The color argument can be either a `RGB` sequence, a `RGBA` sequence or a mapped color index. If using `RGBA`, the Alpha (A part of `RGBA`) is ignored unless the surface uses per pixel alpha (Surface has the `SRCALPHA` flag).

    New in version 1.8: Optional `special_flags`: `BLEND_ADD`, `BLEND_SUB`, `BLEND_MULT`, `BLEND_MIN`, `BLEND_MAX`.

    New in version 1.8.1: Optional `special_flags`: `BLEND_RGBA_ADD`, `BLEND_RGBA_SUB`, `BLEND_RGBA_MULT`, `BLEND_RGBA_MIN`, `BLEND_RGBA_MAX` `BLEND_RGB_ADD`, `BLEND_RGB_SUB`, `BLEND_RGB_MULT`, `BLEND_RGB_MIN`, `BLEND_RGB_MAX`.

    This will return the affected Surface area.

  `scroll`()
    Shift the surface image in place
    scroll(dx=0, dy=0) -> None

    Move the image by dx pixels right and dy pixels down. dx and dy may be negative for left and up scrolls respectively. Areas of the surface that are not overwritten retain their original pixel values. Scrolling is contained by the Surface clip area. It is safe to have dx and dy values that exceed the surface size.

    New in version 1.9.

  `set_colorkey`()
    Set the transparent colorkey
    set_colorkey(Color, flags=0) -> None
    set_colorkey(None) -> None

    Set the current color key for the Surface. When blitting this Surface onto a destination, any pixels that have the same color as the colorkey will be transparent. The color can be an `RGB` color or a mapped color integer. If `None` is passed, the colorkey will be unset.

    The colorkey will be ignored if the Surface is formatted to use per pixel alpha values. The colorkey can be mixed with the full Surface alpha value.

    The optional flags argument can be set to `pygame.RLEACCEL` to provide better performance on non accelerated displays. An `RLEACCEL` Surface will be slower to modify, but quicker to blit as a source.

  `get_colorkey`()
    Get the current transparent colorkey
    get_colorkey() -> RGB or None

    Return the current colorkey value for the Surface. If the colorkey is not set then `None` is returned.

  `set_alpha`()
    set the alpha value for the full Surface image
    set_alpha(value, flags=0) -> None
    set_alpha(None) -> None

    Set the current alpha value for the Surface. When blitting this Surface onto a destination, the pixels will be drawn slightly transparent. The alpha value is an integer from 0 to 255, 0 is fully transparent and 255 is fully opaque. If `None` is passed for the alpha value, then alpha blending will be disabled, including per-pixel alpha.

    This value is different than the per pixel Surface alpha. For a surface with per pixel alpha, blanket alpha is ignored and `None` is returned.

    Changed in version 2.0: per-surface alpha can be combined with per-pixel alpha.

    The optional flags argument can be set to `pygame.RLEACCEL` to provide better performance on non accelerated displays. An `RLEACCEL` Surface will be slower to modify, but quicker to blit as a source.

  `get_alpha`()
    get the current Surface transparency value
    get_alpha() -> int_value

    Return the current alpha value for the Surface.

  `lock`()
    lock the Surface memory for pixel access
    lock() -> None

    Lock the pixel data of a Surface for access. On accelerated Surfaces, the pixel data may be stored in volatile video memory or nonlinear compressed forms. When a Surface is locked the pixel memory becomes available to access by regular software. Code that reads or writes pixel values will need the Surface to be locked.

    Surfaces should not remain locked for more than necessary. A locked Surface can often not be displayed or managed by pygame.

    Not all Surfaces require locking. The `mustlock()` method can determine if it is actually required. There is no performance penalty for locking and unlocking a Surface that does not need it.

    All pygame functions will automatically lock and unlock the Surface data as needed. If a section of code is going to make calls that will repeatedly lock and unlock the Surface many times, it can be helpful to wrap the block inside a lock and unlock pair.

    It is safe to nest locking and unlocking calls. The surface will only be unlocked after the final lock is released.

  `unlock`()
    unlock the Surface memory from pixel access
    unlock() -> None

    Unlock the Surface pixel data after it has been locked. The unlocked Surface can once again be drawn and managed by pygame. See the `lock()` documentation for more details.

    All pygame functions will automatically lock and unlock the Surface data as needed. If a section of code is going to make calls that will repeatedly lock and unlock the Surface many times, it can be helpful to wrap the block inside a lock and unlock pair.

    It is safe to nest locking and unlocking calls. The surface will only be unlocked after the final lock is released.

  `mustlock`()
    test if the Surface requires locking
    mustlock() -> bool

    Returns `True` if the Surface is required to be locked to access pixel data. Usually pure software Surfaces do not require locking. This method is rarely needed, since it is safe and quickest to just lock all Surfaces as needed.

    All pygame functions will automatically lock and unlock the Surface data as needed. If a section of code is going to make calls that will repeatedly lock and unlock the Surface many times, it can be helpful to wrap the block inside a lock and unlock pair.

  `get_locked`()
    test if the Surface is current locked
    get_locked() -> bool

    Returns `True` when the Surface is locked. It doesn't matter how many times the Surface is locked.

  `get_locks`()
    Gets the locks for the Surface
    get_locks() -> tuple

    Returns the currently existing locks for the Surface.

  `get_at`()
    get the color value at a single pixel
    get_at((x, y)) -> Color

    Return a copy of the `RGBA` Color value at the given pixel. If the Surface has no per pixel alpha, then the alpha value will always be 255 (opaque). If the pixel position is outside the area of the Surface an `IndexError` exception will be raised.

    Getting and setting pixels one at a time is generally too slow to be used in a game or realtime situation. It is better to use methods which operate on many pixels at a time like with the blit, fill and draw methods - or by using `pygame.surfarray` pygame module for accessing surface pixel data using array interfaces/`pygame.PixelArray` pygame object for direct pixel access of surfaces.

    This function will temporarily lock and unlock the Surface as needed.

    New in version 1.9: Returning a Color instead of tuple. Use `tuple(surf.get_at((x,y)))` if you want a tuple, and not a Color. This should only matter if you want to use the color as a key in a dict.

  `set_at`()
    set the color value for a single pixel
    set_at((x, y), Color) -> None

    Set the `RGBA` or mapped integer color value for a single pixel. If the Surface does not have per pixel alphas, the alpha value is ignored. Setting pixels outside the Surface area or outside the Surface clipping will have no effect.

    Getting and setting pixels one at a time is generally too slow to be used in a game or realtime situation.

    This function will temporarily lock and unlock the Surface as needed.

  `get_at_mapped`()
    get the mapped color value at a single pixel
    get_at_mapped((x, y)) -> Color

    Return the integer value of the given pixel. If the pixel position is outside the area of the Surface an `IndexError` exception will be raised.

    This method is intended for pygame unit testing. It unlikely has any use in an application.

    This function will temporarily lock and unlock the Surface as needed.

    New in version 1.9.2.

  `get_palette`()
    get the color index palette for an 8-bit Surface
    get_palette() -> [RGB, RGB, RGB, ...]

    Return a list of up to 256 color elements that represent the indexed colors used in an 8-bit Surface. The returned list is a copy of the palette, and changes will have no effect on the Surface.

    Returning a list of `Color(with length 3)` instances instead of tuples.

    New in version 1.9.

  `get_palette_at`()
    get the color for a single entry in a palette
    get_palette_at(index) -> RGB

    Returns the red, green, and blue color values for a single index in a Surface palette. The index should be a value from 0 to 255.

    New in version 1.9: Returning `Color(with length 3)` instance instead of a tuple.

  `set_palette`()
    set the color palette for an 8-bit Surface
    set_palette([RGB, RGB, RGB, ...]) -> None

    Set the full palette for an 8-bit Surface. This will replace the colors in the existing palette. A partial palette can be passed and only the first colors in the original palette will be changed.

    This function has no effect on a Surface with more than 8-bits per pixel.

  `set_palette_at`()
    set the color for a single index in an 8-bit Surface palette
    set_palette_at(index, RGB) -> None

    Set the palette value for a single entry in a Surface palette. The index should be a value from 0 to 255.

    This function has no effect on a Surface with more than 8-bits per pixel.

  `map_rgb`()
    convert a color into a mapped color value
    map_rgb(Color) -> mapped_int

    Convert an `RGBA` color into the mapped integer value for this Surface. The returned integer will contain no more bits than the bit depth of the Surface. Mapped color values are not often used inside pygame, but can be passed to most functions that require a Surface and a color.

    See the Surface object documentation for more information about colors and pixel formats.

  `unmap_rgb`()
    convert a mapped integer color value into a Color
    unmap_rgb(mapped_int) -> Color

    Convert an mapped integer color into the `RGB` color components for this Surface. Mapped color values are not often used inside pygame, but can be passed to most functions that require a Surface and a color.

    See the Surface object documentation for more information about colors and pixel formats.

  `set_clip`()
    set the current clipping area of the Surface
    set_clip(rect) -> None
    set_clip(None) -> None

    Each Surface has an active clipping area. This is a rectangle that represents the only pixels on the Surface that can be modified. If `None` is passed for the rectangle the full Surface will be available for changes.

    The clipping area is always restricted to the area of the Surface itself. If the clip rectangle is too large it will be shrunk to fit inside the Surface.

  `get_clip`()
    get the current clipping area of the Surface
    get_clip() -> Rect

    Return a rectangle of the current clipping area. The Surface will always return a valid rectangle that will never be outside the bounds of the image. If the Surface has had `None` set for the clipping area, the Surface will return a rectangle with the full area of the Surface.

  `subsurface`()
    create a new surface that references its parent
    subsurface(Rect) -> Surface

    Returns a new Surface that shares its pixels with its new parent. The new Surface is considered a child of the original. Modifications to either Surface pixels will effect each other. Surface information like clipping area and color keys are unique to each Surface.

    The new Surface will inherit the palette, color key, and alpha settings from its parent.

    It is possible to have any number of subsurfaces and subsubsurfaces on the parent. It is also possible to subsurface the display Surface if the display mode is not hardware accelerated.

    See `get_offset()` and `get_parent()` to learn more about the state of a subsurface.

    A subsurface will have the same class as the parent surface.

  `get_parent`()
    find the parent of a subsurface
    get_parent() -> Surface

    Returns the parent Surface of a subsurface. If this is not a subsurface then `None` will be returned.

  `get_abs_parent`()
    find the top level parent of a subsurface
    get_abs_parent() -> Surface

    Returns the parent Surface of a subsurface. If this is not a subsurface then this surface will be returned.

  `get_offset`()
    find the position of a child subsurface inside a parent
    get_offset() -> (x, y)

    Get the offset position of a child subsurface inside of a parent. If the Surface is not a subsurface this will return (0, 0).

  `get_abs_offset`()
    find the absolute position of a child subsurface inside its top level parent
    get_abs_offset() -> (x, y)

    Get the offset position of a child subsurface inside of its top level parent Surface. If the Surface is not a subsurface this will return (0, 0).

  `get_size`()
    get the dimensions of the Surface
    get_size() -> (width, height)

    Return the width and height of the Surface in pixels.

  `get_width`()
    get the width of the Surface
    get_width() -> width

    Return the width of the Surface in pixels.

  `get_height`()
    get the height of the Surface
    get_height() -> height

    Return the height of the Surface in pixels.

  `get_rect`()
    get the rectangular area of the Surface
    get_rect(**kwargs) -> Rect

    Returns a new rectangle covering the entire surface. This rectangle will always start at (0, 0) with a width and height the same size as the image.

    You can pass keyword argument values to this function. These named values will be applied to the attributes of the Rect before it is returned. An example would be `mysurf.get_rect(center=(100, 100))` to create a rectangle for the Surface centered at a given position.

  `get_bitsize`()
    get the bit depth of the Surface pixel format
    get_bitsize() -> int

    Returns the number of bits used to represent each pixel. This value may not exactly fill the number of bytes used per pixel. For example a 15 bit Surface still requires a full 2 bytes.

  `get_bytesize`()
    get the bytes used per Surface pixel
    get_bytesize() -> int

    Return the number of bytes used per pixel.

  `get_flags`()
    get the additional flags used for the Surface
    get_flags() -> int

    Returns a set of current Surface features. Each feature is a bit in the flags bitmask. Typical flags are `HWSURFACE`, `RLEACCEL`, `SRCALPHA`, and `SRCCOLORKEY`.

    Here is a more complete list of flags. A full list can be found in `SDL_video.h`

        SWSURFACE      0x00000000    # Surface is in system memory

        PREALLOC       0x01000000    # Surface uses preallocated memory

  `get_pitch`()
    get the number of bytes used per Surface row
    get_pitch() -> int

    Return the number of bytes separating each row in the Surface. Surfaces in video memory are not always linearly packed. Subsurfaces will also have a larger pitch than their real width.

    This value is not needed for normal pygame usage.

  `get_masks`()
    the bitmasks needed to convert between a color and a mapped integer
    get_masks() -> (R, G, B, A)

    Returns the bitmasks used to isolate each color in a mapped integer.

    This value is not needed for normal pygame usage.

  `set_masks`()
    set the bitmasks needed to convert between a color and a mapped integer
    set_masks((r,g,b,a)) -> None

    This is not needed for normal pygame usage.

    New in version 1.8.1.

  `get_shifts`()
    the bit shifts needed to convert between a color and a mapped integer
    get_shifts() -> (R, G, B, A)

    Returns the pixel shifts need to convert between each color and a mapped integer.

    This value is not needed for normal pygame usage.

  `set_shifts`()
    sets the bit shifts needed to convert between a color and a mapped integer
    set_shifts((r,g,b,a)) -> None

    This is not needed for normal pygame usage.

    New in version 1.8.1.

  `get_losses`()
    the significant bits used to convert between a color and a mapped integer
    get_losses() -> (R, G, B, A)

    Return the least significant number of bits stripped from each color in a mapped integer.

    This value is not needed for normal pygame usage.

  `get_bounding_rect`()
    find the smallest rect containing data
    get_bounding_rect(min_alpha = 1) -> Rect

    Returns the smallest rectangular region that contains all the pixels in the surface that have an alpha value greater than or equal to the minimum alpha value.

    This function will temporarily lock and unlock the Surface as needed.

    New in version 1.8.

  `get_view`()
    return a buffer view of the Surface's pixels.
    get_view(<kind>='2') -> BufferProxy

    Return an object which exports a surface's internal pixel buffer as a C level array struct, Python level array interface or a C level buffer interface. The pixel buffer is writeable. The new buffer protocol is supported for Python 2.6 and up in CPython. The old buffer protocol is also supported for Python 2.x. The old buffer data is in one segment for kind '0', multi-segment for other buffer view kinds.

    The kind argument is the length 1 string '0', '1', '2', '3', 'r', 'g', 'b', or 'a'. The letters are case insensitive; 'A' will work as well. The argument can be either a Unicode or byte (char) string. The default is '2'.

    '0' returns a contiguous unstructured bytes view. No surface shape information is given. A `ValueError` is raised if the surface's pixels are discontinuous.

    '1' returns a (surface-width * surface-height) array of continuous pixels. A `ValueError` is raised if the surface pixels are discontinuous.

    '2' returns a (surface-width, surface-height) array of raw pixels. The pixels are surface-bytesize-d unsigned integers. The pixel format is surface specific. The 3 byte unsigned integers of 24 bit surfaces are unlikely accepted by anything other than other pygame functions.

    '3' returns a (surface-width, surface-height, 3) array of `RGB` color components. Each of the red, green, and blue components are unsigned bytes. Only 24-bit and 32-bit surfaces are supported. The color components must be in either `RGB` or `BGR` order within the pixel.

    'r' for red, 'g' for green, 'b' for blue, and 'a' for alpha return a (surface-width, surface-height) view of a single color component within a surface: a color plane. Color components are unsigned bytes. Both 24-bit and 32-bit surfaces support 'r', 'g', and 'b'. Only 32-bit surfaces with `SRCALPHA` support 'a'.

    The surface is locked only when an exposed interface is accessed. For new buffer interface accesses, the surface is unlocked once the last buffer view is released. For array interface and old buffer interface accesses, the surface remains locked until the BufferProxy object is released.

    New in version 1.9.2.

  `get_buffer`()
    acquires a buffer object for the pixels of the Surface.
    get_buffer() -> BufferProxy

    Return a buffer object for the pixels of the Surface. The buffer can be used for direct pixel access and manipulation. Surface pixel data is represented as an unstructured block of memory, with a start address and length in bytes. The data need not be contiguous. Any gaps are included in the length, but otherwise ignored.

    This method implicitly locks the Surface. The lock will be released when the returned `pygame.BufferProxy` pygame object to export a surface buffer through an array protocol object is garbage collected.

    New in version 1.8.

  `_pixels_address`
    pixel buffer address
    _pixels_address -> int

    The starting address of the surface's raw pixel bytes.

    New in version 1.9.2.
