ADVANCED FEATURES
5.1 Overview
The Raptor cards have several advanced features available through
the X Server. They are discussed in the subsections below.
5.2 The 8+8 Mode
This mode is available on Raptor 2100T, Raptor 2500T-DL and Raptor
1100T cards and offers two PseudoColor visuals on the same screen.
Each of these 8-bit visuals offers their own set of planes and
colormap and can be accessed using the standard X Window
function calls such as XGetVisualInfo and XMatchVisual. This
mode can be used for applications that require overlay/underlay
configuration or when two 8-bit applications are required to have their
own installed colormaps. Unlike MOX, which offers several n-bit
layers (where n=1 through 9)), this mode allows only two 8-bit layers
independently.
5.3 MOX (Multiple Overlay eXtension)
MOX (Multiple Overlay Extension) is available with all Raptor cards
(except GFX-8PD) and facilitates multiple graphics layer support.
Each layer can have up to 9 planes. The priority for each of these
layers can be dynamically configured. This type of layering is
particularly useful in Air Traffic Control and Command and Control
applications where each aspect of the drawing is rendered in its own
independent layer.
