I was to write a little tool for viewing SHP(TS/RA2) and SHP(TD/RA) files.
This tool can preview your sprite in the way it will look in-game, with applying TS/RA2 shadows, turrets with offsets and custom color remaps.

The tool was made for Sandbox and OpenRA projects, and now it goes to public.
It is open source under GPLv3. C# Sources can be downloaded at my GIT: http://github.com/katzsmile/OpenRA
The tool is based on SHP(TS) format parser by Banshee, Olaf van der Spek & Stucuk, remap code and SHP(TD/RA) format parser by OpenRA team.
GIF engine by gOODiDEA.NET
Also big thanks to DerDmitry(aka Morpheuz) for his help.
