The markers of selection misbehave after image zoom in

[dma_k]

The problem can be shortly described as follows: when I make a selection on the image (e.g. using a mouse) and then zoom the image in, the eight selection rectangular markers (corner or side) do not function correctly: when the mouse is over them, the cursor pointer does not change the shape indicating the resize of selection, and the is no way to resize the selection. I think, the information about the position of selection markers is not updated correctly after zooming.

The workarounds:

• scroll the image (up/down/left/right) a bit
• switch to another application and back (Alt+Tab, Alt+Tab)

and now the selection is again resizable using the markers.
Steps to reproduce:

1. Open the image (that when zoomed in, will not fit the window and cause scroll bars to appear)
2. Make any selection (I used Ctrl+A) (It does not matter, if selection will fit the window after zooming in or not: the bug is reproducible in both cases, maybe smaller selection is more evident)
3. Zoom image in (I used Alt+MouseScroll). Now the selection cannot be resized using markers.

Environment:

• XnVew v1.97.2
• WinXP Pro EN SP3

Hello !

• I cannot confirm, here I can always resize the selection after the image was zoomed in, using any of the eight grab points…

Claude, thank you very much for testing. I have made corrections on test steps: when you zoom the image in, the image should be larger then your view size, so scrollbars appear – then the drag points do not work. This bug exists for already quite a long time I have re-tested it for v1.97.3 – the same story. I have also found a nice effect: when you zoom in and zoom out (Alt+MouseScroll Up/Down sequentially), the drag points work every 2nd round Very funny.

v1.98.2 – the bug is almost fixed!

I supply the screenshots of xnview before the zoom:


and after the the zoom (I used Ctrl + mouse scroll in, the image was zoomed to 100%):


Notice the mouse pointer does not change the shape. But the resize works at expected position.
