int seGetBitsPerPixel(int DevID, UINT * pBitsPerPixel)
Description:
Determines the color depth of current display mode.
Parameters:
Return Value: ERR_OK
The Drawing section covers HAL functions that deal with displaying pixels, lines and shapes.
int seSetPixel(int DevID, long x, long y, DWORD Color)
Description:
Parameters:
Return Value: ERR_OK
int seGetPixel(int DevID, long x, long y, DWORD *pColor)
Description:
Parameters:
Return Value: ERR_OK
This function reads the SED1355 registers to determine the current color depth and
returns the result in pBitsPerPixel.
DevID
pBitsPerPixel - return value is the current color depth (1/2/4/8/15/16 bpp)
Draws a pixel at coordinates (x,y) in the requested color. This routine can be used
for any color depth.
DevID
x
y
Color
Reads the pixel color at coordinates (x,y). This routine can be used for any color
depth.
DevID
x
y
pColor
- registered device ID
- operation completed with no problems
- Registered device ID
- horizontal coordinate of the pixel (starting from 0)
- vertical coordinate of the pixel (starting from 0)
- at 1, 2, 4, and 8 bpp Color is an index into the LUT.
At 15 and 16 bpp Color defines the color directly
- operation completed with no problems.
- Registered device ID
- horizontal coordinate of the pixel (starting from 0)
- vertical coordinate of the pixel (starting from 0)
- at 1, 2, 4, and 8 bpp pColor points to an index into the LUT.
At 15 and 16 bpp pColor points to the color directly
- operation completed with no problems.
(i.e. rrrrrggggggbbbbb for 16 bpp)
