VDL Options dialog

Figure 1: VDL-Options dialog.

To understand the options in the top part of the dialog, consult Understanding the Display Generator.

Note that several of the options are useful only if SlipStream supplies a video source to be superimposed on the existing image. This is not possible in this release of the hardware.

The CLUT bypass option

While converting the source art, you need to set the CLUT bypass option for the image to force a standard VDL for any pixel for which the high bit is set.
The program that displays the cel needs to set the high bit in the cel using the SetCEControl() function.

The frame buffer will now use the standard (system-supplied) VDL instead of the custom VDL for each pixel that has the high bit set-that is, for each pixel that is part of the specially prepared cel.

Note: You can have transparent and opaque cel pixels on top of an image that uses a custom VDL. Translucent cels will not work correctly even if you have turned on the CLUT bypass option because the cel engine assumes a linear ascending CLUT.
