XnView Software

XnView: MP 0.85 b2 - 64 bit
OS: Windows 10 - 64bit

When zooming into a a large image XnView crashes.

Effect: Program crash

To reproduce:
1. Open an image in XnView's viewer
2. Resize the image to 20.000 x 20.000 pixels using Image » Resize.
3. Zoom into the image (large zoom factor)
Actual behaviour (bug): When zoom factor is at about 1000% XnView crashes

Expected behaviour: Image should be zoomed. No crash

Note: XnView MP 0.84 crashes when creating that large images and it says "File can't be open" when opening large files; therefore I cannot say whether the problem occurs in version 0.84.

XnView: MP 0.85 b2 - 64 bit
OS: Windows 10 - 64bit

Confirmed.

EDIT: I could resize the image to 20000x15000 in 0.84, in the browser, jpg > bmp. No error, no crash when zooming to 1000+% using Num+ (in viewer or fullscreen).

The same image (20000x15000 bmp) always crash in 0.85 b2, when using Num+ to zoom, or just holding it (in viewer or fullscreen).

This problem is supposed to be fixed in XnView MP 0.87. Please check and confirm the bug fix here.

Tested with 0.87 beta 3, fixed.

Resized a 21 mp image (5616x3744) to 20000x13333.
Tested with version 0.86, XnViewMP crashed during zooming in.
Tested with 0.87 beta3, no crash when zomming in to max (1600%) and out an back in on another point.
