Hi, Subbu,
If the sketch has been rotated, this patch seems to produce incorrect results.
Scott, Thanks for trying out the patch. I should have included a warning in my post. The patch only adds flip commands to the viewer of a SketchMorph. The SketchMorph methods themselves are broken. I use the patch to compose sketches with mirror symmetry and then grab the composite for a single sketch. Kludgy, but a stop gap till etoys get true transformation capabilities.
Flips don't work on rotated sketches because the flip* methods of SketchMorph are broken. They switch the form (which resets the rotationCenter) :-(. Rotations, flips, shear and scale, being views on the base image, should affect only the view transform values and not the base form.
Sounds useful to get in for Update.2 - please open a Trac ticket.
