ImageMagick

Interesting. I'm not sure why it's in the news then. Maybe it's because people have old versions installed still?

Anyway, I'll be banning that format as input.

I'm looking for the IM response to CVE-2018–16323. Memory leak in XBM images. I've tried the POC images, but nothing is apparently displayed. Wondering how to to best mitigate.. and check for proper mitigation. ref: https://medium.com/@ilja.bv/yet-another-memory-leak-in-imagemagick-or-how-to-exploit...

The added +repage after the rotate seems to have fixed it.

I've also tried this on IM 7.0.8, and it had the same problem. (Still trying to figure out what all else has changed with that update. )

I'm using this command to rotate and zoom in on an image. convert image.jpg -background transparent -gravity center -scale 200% -rotate 45 -crop800x600+0+0 -trim +repage out.jpg It works in IM 6.7.2-7 but with IM 6.7.8-9 it no longer holds to the center of the image and the image is cropped weird. W...

Hi All,

I'm looking to do a 2x2 collage with overlapping / blended edges.

I can't figure out an easy way to do the overlap / blend part. Any suggestions?

-evaluate multiply 0.5

works great, THANKS!

I'm trying make an image with transparency more see though. I'm using convert image.png -alpha on -channel a -evaluate set 50% out.png However, it removes the areas that were completely transparent and makes them 50%.. So, I'm losing the mask.. How can I keep the mask and bump up the rest of the alp...

they have a lot of designs. It's actually pretty cool to look through.

Hi,

Dunno if you have seen these glasses that produce a 3D effect with Christmas tree lights.

Is there a way to reproduce this effect with IM?

I've seen a star like effect, but this is a bit more complicated pattern

I was just watching this video on how broken color blur is
https://www.youtube.com/watch?v=LKnqECcg6Gw

and noticed the same problem with IM -blur and -gaussian-blur



Notice the dark line in the middle.

Is there an easy way to fix this?

having a problem with batch file processing (bash / linux)
Most images are fine, but a few are incomplete, corrupted during transfer.

How can I test and reject the bad images?

Interesting, I'll look forward to that page..

The WSJ article, I forget can only be accessed from google.

https://www.google.com/search?q=wjs+stipple (should be first result)

it's more of a dot pattern.

Wondering if this is possible with IM. Either stipple like WSJ http://www.wsj.com/articles/SB10001424052748704207504575129961786135180 or engraving like this one http://blog.spoongraphics.co.uk/freebies/free-engraved-illustration-effect-action-for-photoshop looks like that just uses a few textures?

I see what you mean.. The 8x8 was just the enlargement of the detail, post processing.... but it's the 2x2 patchwork that is the real problem

I'm guessing that it's rendered at half the size then enlarged without the regard for contour.

50% then 200% resize does help somewhat.

Hi, I'm using another program that is generating images, however, they have a lot of pixelated noise. Here is an example: https://cloud.githubusercontent.com/assets/13002561/19278731/feb9c1ac-9010-11e6-887b-d601c89e7c1e.png Any advice on removing this pattern, or smoothing the image. The only smooth...
