How to Create a .PCX file using Gimp 2.8 1. Find an Image you like on Wikipedia 1.1 Open it up in GIMP 2.8 1.2 Click 'R' (Rectangle Select) if you want to select just part of the picture. And then Edit/Copy and Edit/Paste As/New Image to see the newly selected image... 1.3 Scale your image Image/Scale Image. Set Width and Height to whatever you need. Tip: Unclip the paperclip to turn off "proportional scaling" 1.4 Make your colormap / palette 1.41 Image/Mode/Indexed 1.42 Set the Color map to "Generate optimum palette" 1.43 Set maximum number of colors=254 1.44 Leave all other settings alone 1.45 Click Convert 1.5 Export a .pcx file 1.51 File/Export 1.52 Name the file: Something.pcx 1.53 Select the folder you want to save the file in 1.54 Click the + sign where it says "Select File Type" 1.55 Scroll to the bottom and choose ZSoft PCX image 1.56 Click Export 1.6 Fix the Palette (make it work with Civ 3) 1.61 Close everything that is open and open up the .pcx file you just created 1.62 Open the color map/palette: Windows/Dockable Dialogs/Colormap 1.63 Make the colormap window bigger so you can see all the colors 1.64 Set the last palette color (color index=255) Set the color to any color that is not in the current palette. Try Magenta (ff00ff) 1.65 Set the second to last palette color (color index=254) Set the color to any color that is not in the current palette. Try neon green (00ff00) 1.66 Fix any white colors Scan the palette. Find any palette color that looks white. If it is ffffff (pure white) then change it to fffff3 (off white) note: I'm not sure if this step is necessary. Pure white seems to work ok. 1.67 File/Overwrite your .pcx file That's it. You now have a .pcx file that can be used in the game.
