sorry hope im not hijacking but this has been bugging me about photomatch, you can't match a photo that has been corrected to 2 point perspective, and if u can't control the photo through the API can u control the guiding lines? like is the any way to lock the blue axis in a vertical possition to force it into 2 point?

It woudnt hurt to have it available as a SU plugin. From a brief read of the description it would probably be of more use to plugin developers, though. If you fancy releasing it you can just post it here. Just start a thread with the title: [plugin]Linalg library.
