|
Notes:
|
||||||
|
- input width and height need to be a multiple of block size
|
||||||
|
- LDR input is 32 bit/pixel (sRGB), HDR is 64 bit/pixel (half float)
|
||||||
|
- for BC4 input is 8bit/pixel (R8), for BC5 input is 16bit/pixel (RG8)
|
||||||
|
- dst buffer must be allocated with enough space for the compressed texture:
|
||||||
|
- 8 bytes/block for BC1/BC4/ETC1,
|
||||||
|
- 16 bytes/block for BC3/BC5/BC6H/BC7/ASTC
|
||||||
|
- the blocks are stored in raster scan order (natural CPU texture layout)
|
||||||
|
- use the GetProfile_* functions to select various speed/quality tradeoffs
|
||||||
|
- the RGB profiles are slightly faster as they ignore the alpha channel
