Enumeration Type Documentation

enum OSL_IMAGE_FLAGS

Constants for the flags member of OSL_IMAGE.

Enumerator:

OSL_IMAGE_SWIZZLED	Image is swizzled.
OSL_IMAGE_COPY	Image is a copy.
OSL_IMAGE_AUTOSTRIP	Image can be automatically stripped (let it one).

enum OSL_LOCATION_FLAGS

Places where to place an image. Values for the argument "location" of some loading routines.

Enumerator:

OSL_IN_NONE	Doesn't exist.
OSL_IN_VRAM	In VRAM.
OSL_IN_RAM	In RAM.
OSL_LOCATION_MASK	There will probably never be more than 8 locations...
OSL_SWIZZLED	Directly swizzle image (only works for oslLoadImage[...] functions!).
OSL_UNSWIZZLED	Force no swizzling (oslLoadImage[...]).

enum OSL_PIXELFORMATS

Pixelformats (color types / modes).

Enumerator:

OSL_PF_5650	16 bits, 5 bits per component, except green which has 6, no alpha
OSL_PF_5551	15 bits, 5 bits per component, 1 alpha bit
OSL_PF_4444	12 bits, 4 bits per component, 4 alpha bits
OSL_PF_8888	32 bits, 8 bits per component, 8 alpha bits
OSL_PF_4BIT	Paletted format, 4 bits (16 colors), cannot be set as drawbuffer.
OSL_PF_8BIT	Paletted format, 8 bits (256 colors), cannot be set as drawbuffer.
