Syntax
sod_img sod_blend_image(sod_img fore, sod_img back, float alpha);Description
Perform linear blending (i.e. image addition) on an input image.
Parameters
sod_img fore
The foreground image. The image can be loaded from disk using sod_img_load_from_file(), from memory (i.e. network socket) via sod_img_load_from_mem() or dynamically created via sod_make_image().
sod_img back

float alpha
Constant weight value.
