The BMP/PCX viewer is made for DOOM/HERETIC/HEXEN/STRIFE BMP/PCX files and other color images. It also displays raw LMP picture data if the data contains a valid DOOM graphic.
Use -devparm on the command line for DOOM and DOOMII and STRIFE to enable screen shots.
Use -ravpic on the command line for HERETIC and HEXEN to enable screen shots.
Press F1 to take a screen shot when the game starts.
All BMP/ PCX files are translated to match the current palette. If the palette does not match the current game, the colors may not display accurately. This is a byproduct of color matching.
Note : Please see Palette Color Matching for controlling the palette matching process.
