Trouble report 22

Images "jump" during manual alignment

Versions affected

V1.0, V1.1, V1.2.

Description

After shifting a few tens of pixels, at some point (several tens of pixels yet to go) the images jump uncontrollably. This happens at a certain pixel location (i.e. one more pixel shift and it 'jumps').

This happens for only 24-bit images, not 45-bit. It happens when the lefthand edge of the righthand image crosses the lefthand edge of the window.

Workaround

Scroll the window so that the lefthand edge of the overlap doesn't cross the lefthand edge of the window.

Status

Fixed in V1.3.
