Normal/Height Map Tool

This little command line tool is used to perform these tasks:

• Pack two distinct normal map and height map files into a single one, store the height in the alpha channel.

• Perform Color based invert on R and/or G channel of a normal map to reoriente the normal vector.

You can find a single .exe file in the Redist folder, if you build the project beware that the ImageProcessor.dll must be merged or bring along with the exe.

Command line usage:

 To pack a normal map file and a height map file in one single file (height map will be stored in alpha channel and the value will be taken in the Red component of the source heightmap if -heightmapchannel is not specified):
 -pack -normalmap:<filepathname> -heightmap:<filepathname> [-heightmapchannel:R|G|B|A] -save:<targetfilepathname>

 To invert the R &| G component of a normal map:
 -invert:<normalmapfilepathname> [-R] [-G] -save:<targetfilepathname>

Acknowledgement
