GPR_$INQ_DRAW_VALUE GPR Calls GPR_$INQ_DRAW_VALUE
NAME
gpr_$inq_draw_value - returns the color used for drawing lines.
FORMAT
gpr_$inq_draw_value (color, status)
DESCRIPTION
This routine returns the color used for drawing lines. To set a new draw
value, use gpr_$set_draw_value.
Output Parameters
color
The color used for drawing lines, in gpr_$pixel_value_t format.
This is a 4-byte integer. Valid values are:
⊕ 0 - 1 For monochromatic displays.
⊕ 0 - 15 An index into a 4-plane color table.
⊕ 0 - 255 An index into an 8-plane color table.
⊕ An index into a 12-plane true-color table.
⊕ 0 - 16,777,215 A color value for a 24-plane true-color pro-
gram.
⊕ -1 For all displays. This specifies that the background is
transparent; that is, the old values of the pixels are not
changed.
⊕ -2 For all displays. This specifies that the draw color is
equal to the bitmap background color. For borrowed displays
and memory bitmaps, the fill background is always zero. For
Display Manager frames and direct mode windows, this is the
pixel value in use for the window background.
status
Completion status, in status_$t format.
