[SOLVED]: Resizing/Cropping based on info from another image

Re: [SOLVED]: Composition clipping/clamping

Oops, a new side-issue surfaced from this, I only just realised... When using an image that is a different proportion, the output is the larger image. Strangely this is different from using "subtract", "add" or "darken", it only happens with "minus". I tried using "+swap" as suggested, but the same ...

Re: Composition clipping/clamping

"Version: ImageMagick 6.9.0-1 Q16 x86 2014-12-22" I need to use this version because it's the latest that my XP single-core machine will run, as far as I can remember. "convert img.png ref.png -compose subtract -composite -negate out.png" I still suspect I need "-set option:compose:clamp=on" (or is ...

[SOLVED]: Composition clipping/clamping

I'm having trouble using "compose", particularly "subtract" with 2 images. It seems that when black is subtracted from black, it cycles those pixels through to white again. In Paint Shop Pro, I get the same result in the "arithmetic" (subtract) method by unchecking the "clip color values" option. Ot...

Re: Help consolidate everything to then 'glob' batch-process (Windows)

Thanks so much fmw42! That all works except for the noise command you mentioned at the bottom, which indeed fails. The whole reason for doing it that way is to make the noise monochrome, or a least less colourful, as mentioned in this thread:- http://www.imagemagick.org/discourse-server/viewtopic.ph...

Help consolidate everything to then 'glob' batch-process (Windows)

I feel terrible to beg for help, but I've been bashing my head against a wall long enough now... (Version: ImageMagick 6.9.0-1 Q16 x86 2014-12-22) I'm trying to turn this BAT file into something that can be 1 line and so be able to *.* batch-process a large amount of files. The reason for splitting ...

Re: Scrolling a tiling image that repeats

Thanks, "roll" was exactly what I was looking for! Now I have a new issue with it, I wanted to do it by a percentage, like 1/8 or 1/16, so 0.125%% or 0.0625%%, but it seems like the command-line doesn't like it for this operation, or doesn't like these kind of percentages. The issue is, I don't know...

Scrolling a tiling image that repeats

"Version: ImageMagick 7.0.7-28 Q16 x64 2018-03-25" Hi, I'm trying to figure out how to scroll a tiling image, so when I shift/translate it x/y, whatever exceeds the bounds of the image will repeat on the opposite side. Something like this:- https://www.parallelcube.com/wp_install/wp-content/uploads/...

Re: Convert to 16bit-channel before blur & resize/dither

Hey-yey!!! I did it. So I actually had to change "-colors 256" to "-colors 255", because 256 seemed to break it. (*should be documented) I also reorganised a couple of things, like you mentioned about the dithering, but now wonderfully it works:- magick image24.png -define png:format=png48 -resize 4...

Thanks for the replies! :) So I uninstalled/reinstalled everything and now it's "Version: ImageMagick 7.0.7-28 Q16 x64 2018-03-25" And so now my BAT file looks like this:- magick image24.png -define png:format=png48 -resize 3072x6144 image48.png magick image48.png -blur 0x3 -depth 16 image48b.png ma...

Re: Convert to 16bit-channel before blur & resize/dither

So I really messed up on the command-line AND I was using the wrong version of ImageMagick! :P Now I have success in getting to 48bit and applying operations, even though I can't see it on these systems, but I'm now having trouble getting back to an 8bit grayscale with nice dithering. To clarify, I'...

[solved] Convert to 16bit-channel before blur & resize/dither

After a couple of hours of sifting through documentation, I'm still no closer to solving this... I would like to take a greyscale image (256 colours), convert it to 16bit-per-channel (65536 colour greyscale), apply some blur, and then convert it back to a 256-colour image with dithering techniques. ...
