Parameters:
Return Value: ERR_OK
int seDrawInkCircle(int DevID, long x, long y, long Radius, DWORD Color, BOOL
SolidFill)
Description:
Parameters:
Return Value: ERR_OK
The value of 'Color' must be 0 to 3. Values 0 and 1 refer to the two user definable
colors. If 'Color' is 2 then the pixel will be transparent and if the value is 3 the pixel
will be an inversion of the underlying screen color.

Color
SolidFill
This routine draws an ellipse with the center located at xc,yc. The xr and yr param-
eters specify the x and y radii, in pixels, respectively. The ellipse will be drawn in
the color specified by 'Color'.
The value of 'Color' must be 0 to 3. Values 0 and 1 refer to the two user definable
colors. If 'Color' is 2 then the pixel will be transparent and if the value is 3 the pixel
will be an inversion of the underlying screen color.
This solid fill option is not yet available for this function.

Color
SolidFill
This routine draws a circle in the ink layer display buffer. The center of the circle
will be at x,y and the circle will have a radius of 'Radius' pixels.
The value of 'Color' must be 0 to 3. Values 0 and 1 refer to the two user definable
colors. If 'Color' is 2 then the pixel will be transparent and if the value is 3 the pixel
will be an inversion of the underlying screen color.
Currently seDrawCursorCircle() does not support the solid fill option.
