Description Dmitry Kazakov 2010-09-04 10:23:05 UTC 
Version:           svn trunk
OS:                Linux

This hotkey centers image to the last point clicked by the Zoom tool, but not to the center of the current screen.

Reproducible: Always

I don't know in 2.3.1 but in current git master (2.4alpha), the zoom-in and zoom-out shortcuts are not centered anymore.

Every other zoom method works as expected (centered on cursor position), like mouse wheel, intuos3 touchstrips, using the zoom tool.

Only the zoom-in/out shortcuts are affected.

Very annoying bug, please fix it.

we're also getting the same problem when cropping, image scaling etc. Quite frustrating when doing real work, as I noticed during my holidays. This really is a critical bug: we cannot release without a fix.

Comment 6 Halla Rempt 2011-10-30 18:41:51 UTC 
However, the actual canvas update is broken. After scaling, we see a small part of the original image, not the scaled image.
Comment 7 Halla Rempt 2011-11-04 19:48:21 UTC 
The original bug got fixed, so we have correct centering, but right now crop, resize, scale etc. are broken because the canvas takes the top-left of the image and shows that no matter what.

Comment 9 Halla Rempt 2011-11-04 20:16:44 UTC 
On undo of crop, the positioning of the image on the canvas is still wrong.

just a picture scenario of what happen with cropping tool :

-> workaround to refresh at the end : make the layer blink ( hide/unhide with the little eye icon )
