I can never remember the syntax for cropping a single row of pixels using ImageMagick, hence the title of the post where I elude to the fact I want to crop a single row of pixels with ImageMagick.

For a row:

$ magick convert $INPUT -chop 0x1 +repage $OUTPUT

For a column:

$ magick convert $INPUT -chop 1x0 +repage $OUTPUT

I probably keep forgetting because I want -crop, not -chop.

While I’m here, thanks to the ImageMagick team for their amazing toolkit, and kwm@ and adam@ for maintaining the FreeBSD Port and pkgsrc packages!
