Automatic Cropping does not work

[Guest]

To reproduce, do this:

With any image in Viewer, go to Image -> Canvas size (Shift+C).
Increase canvas by a few pixels and take note of the background color.

Then go to Image -> Automatic crop (Alt+Y).
Use the same background color as above.

Image is unaltered.

This bug is new. IIRC, in v1.95.2 automatic cropping worked correctly, since I cropped a large number of files (might have been v1.94.2).

Works fine for me in XnView 1.95.1 and XnView 1.95.4.

Is the image you crop true colour (RGB) or does it have a colour palette?

This happens when the background color is not black or white.

It happened to me with the colors (R,G,B): (76,192,248) & (112,160,232).

I then tested with a few other custom colors and it also didn't work.

Then I tested with Black (0,0,0) and White (255,255,255) and it worked.

BTW, all the images used were 24-bit JPEG. They were images I wanted to use as wallpaper with aspect ratios that didn't fit my screen. Instead of cropping and resizing, I added a border.

Please post a sample file?

Hi,

I'm having the same issue; a sample image can be found below (24-bit RGB PNG, background color (58,110,165)):

Remarkably, in batch processing the Auto crop transformation does work as desired.
It'd be great if this bug could be fixed.

Thanks,

Erik

Confirmed. With your above sample image, automatic cropping just does not work, not even when specifying a high tolerance.

Please try XnView 1.97.7
