I’m working with the Kantan Mapper to precisely reposition and keystone some video projections onto a gallery wall. Because this is actual video content, it is important that it isn’t warped and that the original aspect ratio is maintained; however, there doesn’t seem to be a way to lock the aspect ratio when using the Select Shape tool.
Is there some way to lock the aspect ratio when moving the handles (along the lines of holding shift when cropping an image in Photoshop), or is there some way to adjust the scale values so that both x and y values are affected together and proportionally.
