X23A-G-003-07 Issue Date: 01/02/05
lut[x][1] == GREEN component
l ut[x][2] == BLUE component
Count - the number of LUT entries to write.
Return Value: ERR_OK - operation completed with no problems
int seGetLut(int DevID, BYTE *pLUT, int Count)
Description: This routine reads one or more LUT entries and puts the result in the byte array
pointed to by pLUT.
A Look-Up Table entry consists of three bytes, one each for Red, Green, and Blue.
The color information is stored in the four most significant bits of each byte.
Parameters: DevID - registered device ID
pLUT - pointer to an array of BYTE lut[16][3]
pLUT must point to enough memory to hold
Count
x 3 bytes of data.
Count - the number of LUT elements to read.
Return Value: ERR_OK - operation completed with no problems
int seSetLutEntry(int DevID, int Index, BYTE *pEntry)
Description: This routine writes one LUT entry. Unlike seSetLut, the LUT entry indicated by
Index
can be any value from 0 to 255.
A Look-Up Table entry consists of three bytes, one each for Red, Green, and Blue.
The color information is stored in the four most significant bits of each byte.
Parameters: DevID - registered device ID
Index - index to LUT entry (0 to 255)
pEntry - pointer to an array of three bytes.
Return Value: ERR_OK - operation completed with no problems
int seGetLutEntry(int DevID, int index, BYTE *pEntry)
Description: This routine reads one LUT entry from any index.
Parameters: DevID - registered device ID
Index - index to LUT entry (0 to 255)
pEntry - pointer to an array of three bytes
Return Value: ERR_OK - operation completed with no problems
int seSetBitsPerPixel(int DevID, UINT BitsPerPixel)
Description: This routine sets the system color depth. Valid arguments for
BitsPerPixel
is are: 1,
2, 4, 8, 15, and 16.
After performing validity checks for the requested color depth the appropriate
