Parameters:
Return Value: ERR_OK - operation completed with no problems
int seDrawRect(int DevID, long x1, long y1, long x2, long y2,
DWORD Color, BOOL SolidFill)
int seSetLut(int DevID, BYTE *pLut, int Count)
This routine draws and optionally fills a rectangular area of display buffer. The
upper right corner is defined by x1,y1 and the lower right corner is defined by x2,y2.
The color, defined by Color, applies both to the border and to the optional fill.
DevID
x1, y1
x2, y2
Color
SolidFill
This routine writes one or more LUT entries. The writes always start with Look-Up
Table index 0 and continue for 'Count' entries.
A Look-Up Table entry consists of three bytes, one each for Red, Green, and Blue.
The color information is stored in the four least significant bits of each byte.
DevID
pLut
Count
- registered device ID
- top left corner of the rectangle (in pixels)
- bottom right corner of the rectangle (in pixels)
- The color to draw the rectangle outline and fill with
- Color is an index into the Look-Up Table.
- Flag whether to fill the rectangle or simply draw the border.
- Set to 0 for no fill, set to non-0 to fill the inside of the rectangle
- registered device ID
- pointer to an array of BYTE lut[16][3]
- the number of LUT entries to write.
lut[x][0] == RED component
lut[x][1] == GREEN component
lut[x][2] == BLUE component
