GetForeColor

Use the GetForeColor procedure to obtain the color of the foreground color for the current graphics port.

PROCEDURE GetForeColor (VAR color: RGBColor);

color

An RGBColor record.

DESCRIPTION

In the color parameter, the GetForeColor procedure returns the RGBColor record for the foreground color of the current graphics port. This procedure operates for graphics ports defined by both the GrafPort and CGrafPort records. If the current graphics port is defined by a CGrafPort record, the returned value is taken directly from the rgbFgColor field.

If the current graphics port is defined by a GrafPort record, then only eight possible RGB values can be returned. These eight values are determined by the values in a global variable named QDColors, which is a handle to a color table containing the current QuickDraw colors. These colors are listed in Table 4-4 on page 4-62. This default set of colors has been adjusted to match the colors produced on the ImageWriter II printer.

SPECIAL CONSIDERATIONS

This procedure is available for basic QuickDraw only in System 7.

SEE ALSO

You can use the RGBForeColor procedure, described on page 4-61, to change the foreground color.
