NAME

       SDL_SetTextureAlphaModFloat - Set an additional alpha value multiplied into render copy operations.

SYNOPSIS

       #include <SDL3/SDL_render.h>

       bool SDL_SetTextureAlphaModFloat(SDL_Texture *texture, float alpha);

DESCRIPTION

       When  this  texture  is  rendered,  during the copy operation the source alpha value is modulated by this
       alpha value according to the following formula:

       srcA = srcA * alpha

       Alpha modulation is not always supported by the renderer; it will return false if alpha modulation is not
       supported.
