snibgo, thank you. It was a jpeg artifact. When I created this pic there were no pixels except pure white.

If you intend to trim them off, use a larger fuzz.

Why?
2% * 256 = 5
It means that trim should cut off pixels in the range 250-255. That is left column 5 pixels wide. Check the image 0 in this topic above, you won't find pixels darker than 250 in the left white column (5 pixels).

These images ...

It seems to work fine, but I don't know what you intend.

It's clearly visible here. Take a look at upper red image. It is not in the center, it moved a few pixels to the right from the center. Left white column is is a few pixels wider than right white column. I'd like to get both left and right ...

Red image is slightly moved to the right.

Oops. I can't delete my messages.

To shave 2 pixels from all sides, use "-shave 2x2".


Unfortunately the top image is still not in the center.

@echo off
setlocal enabledelayedexpansion

for /f "tokens=1,2 delims=:" %%x in ('magick 0.jpg -shave 2x2 -fuzz 2%% -trim +repage -format %%w:%%h +write info: NULL:') do set /a "w1 ...

That page also gives the correct syntax for "-crop".

"-crop +2+2+2+2" is not valid IM syntax, although IM does accept it. It doesn't do the same as "-crop 2x2+2+2". What do you want it to do? I suggest you use valid syntax.


Thank you, snibgo. But I don't know the valid syntax. I have read the manual but didn't find how to cut off 2 pixels from ...

This imagemagic code crops 2 pixels then crops same color borders and then scales and places images to the center:
@echo off
setlocal enabledelayedexpansion

for /f "tokens=1,2 delims=:" %%x in ('magick 0.jpg -crop +2+2+2+2 -fuzz 2%% -trim +repage -format %%w:%%h +write info: NULL:') do set /a "w1 ...

I found better way:

snibgo, Thank you.

Is it possible to do with ImageMagic?

Thank you very much. I forgot minus.
