int seDrawRect(int DevID, long x1, long y1, long x2, long y2,
DWORD Color, BOOL SolidFill)
Description:
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.
Parameters:
DevID
- registered device ID
x1, y1
- top left corner of the rectangle (in pixels)
x2, y2
- bottom right corner of the rectangle (in pixels)
Color
- The color to draw the rectangle outline and fill with
- Color is an index into the Look-Up Table.
SolidFill
- 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
Return Value: ERR_OK - operation completed with no problems.
9.2.7 LUT Manipulation
These functions deal with altering the color values in the Look-Up Table.
int seSetLut(int DevID, BYTE *pLut, int Count)
Description: 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.
Parameters: DevID
-
registered
device
ID
pLut
- pointer to an array of BYTE lut[16][3]
lut[x][0] == RED component
lut[x][1] == GREEN component
lut[x][2] == BLUE component
Count
- the number of LUT entries to write.
Return Value: ERR_OK - operation completed with no problems
