When ImageMagick, ffmpeg, and Pandoc broke for good, we had a bit of a problem.

Hey #ImageMagick users, how do you stack two images of different sizes together, so that they are both centered in the frame?

@villares
This. I work in film-making and animation and I'm always hacking away in#VSCode.
In the Adobe #AfterEffects user community a good deal of the discussion is about #JavaScript, because that's the language it uses for automation. Similarly for #Blender, a working knowledge of #python is really helpful, #DaVinciResolve uses #Lua and of course there are command line tools like #ffmpeg and #ImageMagick that means having shell scripting skills becomes a superpower.

I love running simulations but exploring the parameter space is murder.

Here I'm experimenting with loop animations, showing how three summaries change as a single variable changes, across 18 methods.

If I stare at this long enough I will either hypnotise myself or achieve enlightenment.

Animation with three panels. One of 18 scatterplots in a lattice, one a line plot with 18 lines, and the third a single scatterplot, all redrawn as a parameter changes.

@resing Yes, that’s it. Look at some of the examples, you’ll see that it either pretends there is no image or it shows an empty box where a thumbnail should be.

Most links provide some og:image (og is #OpenGraph) for third parties to use. If the image behind the og:image header is a #WebP or #AVIF format then the #Mastodon server fails to process it. Most likely due to a #ImageMagick issue.

@MeanestBossEver #commandline or #gui?
I often use #imagemagick and #pdftk

i wonder how difficult and CPU intensive it would be to add a component like #Glaze to and image upload processor...

Like, take you federation post, when you attach media, could glaze or #imageMagick or even #ffmpeg process the upload? Users could opt-in or out to having protections applied to an upload. I get that it's an AI arms race now, but i guess this is the next actionable option?

Could someone with experience with ImageMagick, Mastodon development, JPEG, WebP or AVIF please have a look at this Mastodon issue regarding link previews?

Does the diagnosis make sense?
Do the proposed solutions make sense? Is it easy to implement those fixes?

The #camera trap was set up wrong and took a picture every 5 seconds, with or without movement detected. 🤦

I want to #analyze the images to see if there's accidentally anything interesting in there. I'm not going to look at them, I have computers here, and they're supposed to be good at this kind of thing.

Currently reading about #imagemagick #compare. :masto_reading:

The files have a natural chronological order, so I'm thinking of comparing each file to the next one. If the difference is above a threshold (which one?!), I might look at the second image myself.

Any other suggestions?

upgrade to #mastodon 4.1.3 caused a bunch of issues with images, which were rooted in an older version of #imagemagick not playing nice. unfortunately, that was the last version available in our distro (it was still on LTS fwiw). ended up having to do a distupgrade, which broke a bunch of things.

node wasn't there after a reboot, so mastodon-streaming wouldn't start. simple: install node.

mastodon-web couldn't start because it couldnt find libffi.so.6 even though libffi.so.7 _was_ present. shamefully, I symlinked 7 to the path for 6, and then it worked again.

I have some more things to do, including a database upgrade, but all that can wait. this has been one hell of a morning.

I've never run in to this before.

#python + #matplotlib makes it relatively easy to make graphs but nightmarish to make #animation visualizations. In simple cases, I like to just save images and use #imagemagick to animate

I've got a case here where is simply refuses to finish all the images. They are there and displayable. #ffmpeg has no problem making an mp4

Reducing the image size fixes it. Is there a max anim size for imagemagick?

using `convert` rather than `animate` stops at 10MB...?

FYI The hoop jumping i had to go through to convert from svg->png.

1. needed to call rsvg-convert directly
2. needed to add zoom because that makes it look better (regardless of amount)
3. needed to crop because for some reason there were always extra pixels of transparent border on the right and bottom
4. needed to delete bogus files #imagemagick _sometimes_ created with cropped off bits and ...? and rename the one i wanted.

(screenshot is written in fish shell)

#imagemagick geeks: why am i getting multiple output files here

convert foo.png -gravity NorthEast -crop 1097x339 +repage foo-cropped.png

this generates foo-cropped-0.png foo-cropped-1.png foo-cropped-2.png foo-cropped-3.png

I only want the file in foo-cropped-0.png and i want it to be called foo-cropped.png

what am i doing wrong? It's like giving me all the bits it chopped off too, instead of just the resulting cropped file.

masukomi

TIL that even when #imagemagick is configured to use rsvg-convert to convert SVG to PNG it ... doesn't? Or does so in a way that makes the results unusably bad.

BUT if you use invoke rsvg-convert directly it works fine.

Also BONUS pro tip. The results were very meh UNTIL i added zoom, and then suddenly everything was crisp and sharp. Didn't really matter how much zoom i added, just that the zoom functionality got invoked.

Of course #ImageMagick 's Image ping method doesn't actually do what it says:
| Ping image header into Image() object, but without any pixel data.
| This is useful for inspecting image meta-data without decoding the
| whole image.

Used that and metadata was missing most of the metadata that is included in a normal open.

(Yes, #ImageMagick perhaps can do this entire construction in one step. It certainly can do "-flatten". Indeed, I used "display -flatten" to check my work as I wrote the code. But I wanted to use Netpbm, for reasons.)

@jaredwhite @cappiello @vanilla @bridgetown Oh, I know. I'd prefer to stick with back-end development (.NET, C#, ASP.NET, SQL Server) because I'm familiar with it and I only got into coding because it pays better than cleaning toilets, but I keep landing in projects that want full-stack so I must perforce adapt.

On my personal website, though, my stack is #make, #bash, #sed, #awk., #pandoc, #htmlXmlUtils, and #ImageMagick. Deployment is #rsync over #ssh. :)

This morning, #DockPress gained Ghostscript support, meaning uploading PDF files into the #WP Media Library will be guaranteed to result in a nice thumbnail of your PDF.

This solves the problem of Debian and Ubuntu builds of #ImageMagick — which handles image processing in WordPress — blocking out PDF support by default because of an old security issue.

As what runs within a DockPress container is "trusted", the potential security issue is less of a concern.

Was looking for a way to determine the #compression quality of some #JPEGs. Turns out #ImageMagick can do this:

identify -format '%Q\n' ecur-001.jpg

Result:

Command below processes all files in a directory, with result to CSV file:

identify -format '%f,%Q\n' ./images-BKT/* > BKT-quality.csv

I'm passing image information to #ImageMagick by outputting a MIFF header
https://imagemagick.org/script/miff.php
before the binary data. Problem is:
1. I haven't found a way to pass the “quantum scale” or “quantum range” information through the header (i.e. the fact that the maximum value is 1023 and not 65535)
2. I haven't found a way to tell it that the upcoming binary data would be band sequential, which would allow me to not interleave it in BIP form.
Maybe I can #askFedi if this can be done, and how?
