GPR_$SET_TEXT_VALUE GPR Calls GPR_$SET_TEXT_VALUE
NAME
gpr_$set_text_value - specifies the color to use for writing text.
FORMAT
gpr_$set_text_value (color, status)
DESCRIPTION
This routine specifies the color to use for writing text.
The default text value is 1 for borrowed displays, memory bitmaps, and
Display Manager frames on monochromatic displays; 0 for Display Manager
frames on color displays.
For monochromatic displays, only the low-order bit of the text value is
considered because monochromatic displays have only one plane.
For color displays in 4-bit pixel format, only the four lowest-order bits
of the text value are considered because these displays have four planes.
Input Parameters
color
The color to be used for writing text, in gpr_$pixel_value_t format.
This is a 4-byte integer. The valid values are listed below:
⊕ 0 - 1 For monochromatic displays.
⊕ 0 - 15 An index into a 4-plane color table.
⊕ 0 - 255 An index into an 8-plane color table.
⊕ 0 - 4096 An index into a 12-plane true-color map
⊕ 0 - 16,777,215 A color value for a 24-plane true-color pro-
gram.
Output Parameters
status
Completion status, in status_$t format.
