- ** $VER: RenderAsHAM.fred 1.2.0 (24.10.93)
- **
- ** This program can be run from an InvokeADPro list to convert images
- ** into HAM. Including this program automatically causes a pre program
- ** to be executed as well (to select the screen modes).
- **
- ** Clips Imported:
- ** FREDScreenType - Screen type to be used
- ** FREDLockPalette - ~0 if locked palette wanted
- ** 0 if floating palette wanted
- ** defined in a SaveAs pre script
- ** FREDDither - Which dither to use
- ** FREDDitherAmt - Dither amount to be used
- ** FREDHAMType - Render as HAM(6) or HAM8
- **
- ** NOTE: Clip names are case sensitive.
- **
- ** This script requires FRED v1.4.0 (or higher) to run. Also required is
- ** ADPro v2.5.0 (or higher).
