# G2_SetBlendBrightness

## C Specification

      #include <nitro/gx/g2.h>

      void G2_SetBlendBrightness(
          int plane /* GXBlendPlaneMask */,
          int brightness
      );

## Arguments

plane | Selects the plane where the brightness will be changed (result of a logical OR with the `GXBlendPlaneMask` type values)
brightness | Specifies the coefficient for brightness change (-16 ≤ `brightness` ≤ 16)

## Return Values

None.

## Description

This function changes the brightness of the screen specified by `plane`. If `brightness` is positive, the brightness increases; if it is negative, the brightness decreases. See `G2_SetBlendAlpha` for details on the `GXBlendPlaneMask` type.
