iwd-tool, a command-line tool for generating iwd files. The main purpose of this tool is to filter out duplicated images between Call of Duty: Modern Warfare 2 and Call of Duty: Online.

|- iw4_images
|- codo_images
|- iwd_tool.exe
|- dump.cfg
dumpraw images/white.iwi
dumpraw images/black.iwi
First you need to create a .cfg file with all the images you want to include in your IWD. IW4x can generate this file automatically by starting the game with -dump. Execute the following command to find all the required images: ./iwd-tool.exe <cfg file>. For example: ./iwd-tool.exe dump.cfg
