This command:
Results in this image for me:

Note the image size of 102x102, and a 2px green border on the bottom and right egde.

When I run the same command with "-resize" instead of "-distort resize", I get a 100x100 image without border:


I would have expected both commands to produce a 100x100 image without border.
Why is -distort resize behaving differently, and how can I prevent it?
(I prefer to use -distort resize because of the better result quality, especially when upscaling.)

ImageMagick version: 6.9.2-6 Q16 x86_64 2015-12-06, on Linux.

Remove the virtual canvas:

• convert netscape: -distort resize 100x100! +repage -flatten x.png

That seems to work in my case, thanks!

I'm still a little worried about the "-distort resize" behavior though, since I don't understand why it happens.

The extra pixels come from the -flatten option, not -distort. The -flatten option respects any virtual canvas.

But "-distort" is responsible for extending the virtual canvas in this strange way, isn't it?
Is it supposed to do that?

The -distort resize option is a special case for distort, it does not extend the virtual canvas.

I believe there is a problem with -distort resize. The resulting image virtual canvas is indeed 102x102+0+0 rather than 100x100+0+0.

We can reproduce the problem you posted and have a patch in ImageMagick 6.9.2-10 Beta, available by sometime tomorrow. Thanks.

Good to know, thanks!
