When you create a presentation space, the current marker set, along with other marker attributes, are set to default. The current marker symbol (the cross described earlier) is specified from the supplied marker set. The supplied set of marker primitives contains only image, or raster, marker primitives.
The marker primitives in the default marker set are drawn by setting the color of the pels in the marker box. Within the marker box, the color of the set pels defines the foreground color. The default foreground color is neutral- black on the display screen and on printers.
The color of the pels that are not set defines the background color. The default background color is the background color on the device-white on the display screen, and the loaded paper color on printers. The default background mix is LEAVE_ALONE, or transparent, which means the background color is irrelevant.
If the default set is changed using GpiSetDefAttrs, its markers are not accessible. The markers from the default set can be recovered by calling GpiSetDefAttrs and specifying the value LCID_DEFAULT, (0).
