blit_with_alpha() [1/2]

template<bool overlay = false>

static void blit_with_alpha ( video::IImage * src, video::IImage * dst, v2s32 dst_pos, v2u32 size )

static

Draw an image on top of another one with gamma-incorrect alpha compositing.

This exists because IImage::copyToWithAlpha() doesn't seem to always work.

Template Parameters

overlay

If enabled, only modify pixels in dst which are fully opaque. Defaults to false.

Parameters

src	Top image. This image must have the ECF_A8R8G8B8 color format.
dst	Bottom image. The top image is drawn onto this base image in-place.
dst_pos	An offset vector to move src before drawing it onto dst
size	Size limit of the copied area
