9.4.6 Drawing

The Drawing routines cover HAL functions that deal with displaying pixels, lines and shapes.

int seSetPixel(long x, long y, DWORD Color)

Description: Draws a pixel at coordinates (x,y) in the requested color. This routine can be used for any color depth.

Parameters: x	- horizontal coordinate of the pixel (starting from 0)
y	- vertical coordinate of the pixel (starting from 0)
Color	- at 1, 2, 4, and 8 bpp Color is an index into the LUT.
	At 15 and 16 bpp Color defines the color directly
	(i.e. rrrrrggggggbbbbb for 16 bpp)
Return Value: ERR_OK	- operation completed with no problems.

int seGetPixel(long x, long y, DWORD *pColor)

Description: Reads the pixel color at coordinates (x,y). This routine can be used for any color depth.

Parameters: x	- horizontal coordinate of the pixel (starting from 0)
y	- vertical coordinate of the pixel (starting from 0)
pColor	- 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
	(i.e. rrrrrggggggbbbbb for 16 bpp)
Return Value: ERR_OK	- operation completed with no problems.

int seDrawLine(int x1, int y1, int x2, int y2, DWORD Color)

Description: This routine draws a line on the display from the endpoints defined by x1,y1 to the endpoint x2,y2 in the requested 'Color'.

Currently seDrawLine() only draws horizontal and vertical lines.

Parameters: (x1, y1)	- first endpoint of the line in pixels
(x2, y2)	- second endpoint of the line in pixels (see note below)
Color	- color to draw with. 'Color' is an index into the LUT.

Return Value: ERR_OK - operation completed with no problems

Note

Functionality differs from the 135x HAL.
