Classes
struct	fastuidraw_compute_image_atlas_coord_type
	Structure to give information about what tile and where within a tile an image texel is located. Only available if FASTUIDRAW_IMAGE_ATLAS_DISABLED is not defined. More...

struct	fastuidraw_image_extended_info_type
	Structure that fully describes a fastuidraw::Image or a sub-image of one. Only available if FASTUIDRAW_IMAGE_ATLAS_DISABLED is not defined. More...

struct	fastuidraw_image_info_type
	Structure that describes the relationship between the master index tile and the color tiles of an image. Only available if FASTUIDRAW_IMAGE_ATLAS_DISABLED is not defined. More...

struct	fastuidraw_image_texture_gather_output_type
	Structure that holds the 2x2 texel block. Only available if FASTUIDRAW_IMAGE_ATLAS_DISABLED is not defined. More...
