Hello Robert, I pulled a request. I haven't added command line functionality for the algorithms yet. For now, the only way to test them is:
1. Extract this archive(the same from previous message) to some location. http://www.mediafire.com/?nefag5h5w7e1o74 2. Change the variable "path" on line 1497 in oiiotool.cpp, to the location you extracted. 3. Replace your oiiotool.cpp with the one from the archive. 4. In the archive you will find folder "ip", and in it folders for each group of algorithms such as corners, edges, etc. In each there is tests folder. In there you will find code for each algorithm, that you need to copy to oiiotool.cpp in order to test the algorithm. Basically you just replace the code in main in oiiotool.cpp. Stefan On 3/25/12, Robert Matusewicz <[email protected]> wrote: > Hi, > > Could You prepare a pull request from Your changes?
