Long Description
-----------------------------------------------------------------------------
This is a description of all currently supported colormodels:
PIXFMT_LUT8
This color model is the normal one. One Byte, one pixel. The value is used as
an index to a color lookup table.
PIXFMT_RGB15
In this mode all pixels consist of one word. But now this value is no index to
a clut anymore, it is the direct color value. Each value (red,green or blue)
is defined by 5 bits. This makes a sum of 15 bits, one bit in the word is
unused. 32768 color values are possible with this color scheme. This color
model is used by the Cybervision board for example.
XRRRRRGG GGGBBBBB (Each letter represents one bit in a 16bit word)
PIXFMT_BGR15
This coding scheme is the same as PIXFMT_RGB15 but the red and blue values
are exchanged.
XBBBBBGG GGGRRRRR
PIXFMT_RGB15PC
Same as PIXFMT_RGB15 but low and high byte are swapped in the word.
GGGBBBBB XRRRRRGG
PIXFMT_BGR15PC
Same as PIXFMT_BGR15 but low and high byte are swapped just like in
PIXFMT_RGB15PC
GGGRRRRR XBBBBBGG
PIXFMT_RGB16
This format is similar to PIXFMT_RGB15 but now 6 bits are used for the green
value. This makes a total of 65535 colors. The coding scheme is as follows:
RRRRRGGG GGGBBBBB
PIXFMT_BGR16
Same as PIXFMT_RGB16 but the red and blue values are exchanged.
BBBBBGGG GGGRRRRR
PIXFMT_RGB16PC
This is the same like PIXFMT_RGB16 but the low and high byte are swapped.
GGGBBBBB RRRRRGGG
PIXFMT_RGB24
This color model uses 3 bytes per pixel or 8 bits per color usually called
true color mode. With this model you have 16777216 colors available. format.
Each color component may have one of 256 levels:
RRRRRRRR GGGGGGGG BBBBBBBB
PIXFMT_BGR24
Same as PIXFMT_RGB24 but with red and blue values swapped.
BBBBBBBB GGGGGGGG RRRRRRRR
PIXFMT_ARGB32
This color model represents true color mode with alpha channel. The
Cybervision board introduces this model. 4 bytes per pixel (or one long word)
is used. This allows very fast access to the graphics data but needs very
much memory.
AAAAAAAA RRRRRRRR GGGGGGGG BBBBBBBB
PIXFMT_BGRA32
Same as PIXFMT_ARGB32 but the bytes in a word are swapped AND the words in the
longword are swapped, too.
BBBBBBBB GGGGGGGG RRRRRRRR AAAAAAAA
