Histogram Output Oddness

Hi everyone! I hope you are well during this crazy time. I'm having an oddity with histogram output: convert in.jpg -alpha off -depth 8 -flatten -separate -append -strip -define histogram:unique-colors=false histogram:histo.gif is outputting a fine global histogram, except it has a huge spike in the...

PSD/PSB Maximize Compatibility Extraction not failing when it should

If you: convert filename.psb[0] output.jpg and the file was saved WITHOUT maximizing compatibility, it renders a horribly inaccurate mess of a file, when in fact it should fail totally and report that no data was found. Thanks for your attention to this matter, and for this wonderful software! This ...

Re: PAID: Build self-contained macOS binary

I built JPEG per Magick’s instructions, moved it into the IM directory, then built IM. It saw it fine it just failed to include it because it didn’t pass all tests (see above).

Re: PAID: Build self-contained macOS binary

Thanks, Fred. But will this create a self-contained portable binary I can distribute with my software? That is my aim.

PAID: Build self-contained macOS binary

Hi there! Thanks to all for such wonderful work and collaboration. I'm writing in hopes of finding someone intimate with the build process who can build a macOS binary of ImageMagick 7.x whose sole purpose is to extract embedded previews from Photoshop files: filename.psd[0] I believe this only requ...

Fastest Comparison Method?

I simply want to compare two images and know if they are visually different at all. (They will be the same size.)

I know of the AE compare metric, of IM image signatures... but what is the FASTEST method to do this?

Thanks for your consideration!
