Converts from 32bit premultiplied 8:8:8:8 to 32bit 8:8:8:8 format, using an inversion table instead of division.

Inversion table should be a table of 256 XFcFixed's, defined as division between 255 and n (ranging from 0 to 255).

Typedef Documentation

typedef void(* xfcPixelBufferConversionFunction)(void *, void *, INT32)
 

typedef UINT32(* xfcPixelConversionFunction)(UINT32)
 

Utility for pixel format conversions.

Due to the obvious overhead this is mostly for convenience class, and not meant for heavy realtime use.

Note:
Pixel format conversions tend to cause loss of information, especially for the alpha values.
Pixel format explanation: 
        565 - 16bit r:g:b format
       55X5 - 16bit r:g:x:b format
       X888 - 32bit x:r:g:b format (alpha ignored)
     X6X5X5 - 32bit 565565 bit format that's handy for fast 16bit image manipulation (XGXRXB)
 

       8888 - 32bit a:r:g:b format
       1555 - 16bit a:r:g:b format
       5515 - 16bit r:g:a:b format
    1X5X5X5 - 32bit 1556555 bit format, same as above, but with alpha on topmost bit (AXGXRXB)
 Premul8888 - 32bit a:r:g:b format, color values are premultiplied with alpha
See the XFCGFXFORMAT enumeration for graphics format constants.
