Return Value: ERR_OK
int seDrawRect(int DevID, long x1, long y1, long x2, long y2, DWORD Color, BOOL
SolidFill)
Description:
Parameters:
Return Value: ERR_OK
int seDrawEllipse(int DevID, long xc, long yc, long xr, long yr, DWORD Color, BOOL
SolidFill)
DevID
x
y
pColor
This routine draws a line on the display from the endpoints defined by (x1,y1) to
(x2,y2) in the requested Color.
seDrawLine() supports horizontal, vertical, and diagonal lines.
DevID
(x1, y1)
(x2, y2)
Color
ERR_INVALID_REG_DEVICE - device argument is not valid.
This routine draws and optionally fills a rectangular area of display buffer. The
upper right corner of the rectangle is defined by (x1,y1) and the lower right corner
is defined by (x2,y2). The color, defined by Color, applies to the border and to the
optional fill.
DevID
(x1, y1)
(x2, y2)
Color
SolidFill
- 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.
- registered device ID.
- top left corner of line
- bottom right corner of line (see note below)
- color of line
- For 1, 2, 4, and 8 bpp, 'Color' refers to the pixel value which points to
the respective LUT/DAC entry.
- For 15 and 16 bpp, 'Color' refers to the pixel value which stores the
red, green, and blue intensities within a WORD.
- operation completed with no problems
- 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 solid fill
- At 1, 2, 4, and 8 bpp Color is an index into the Look-Up Table.
- At 15/16 bpp Color defines the color directly
(i.e. rrrrrggggggbbbbb for 16 bpp)
- 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
- operation completed with no problems.
(i.e. rrrrrggggggbbbbb for 16 bpp)
