I'm looking for a way to created an animated "typewriter" effect using imagemagick, similar to what can be done with this online tool. http://wigflip.com/screedbot/ Here's one that I made https://i.imgur.com/kbdLkKh.gif Ideally I would like to be able to read text from a .txt file (including line ...

To do it accurately, you could examine the GMIC script and find equivalent operations in IM. I had a look at GMIC and it seems like the polygonize effect is a whole effect in itself (fx_polygonize_preview) so, unless I learnt C++ I don't think I could convert it to ImageMagick To polygonalize, you ...

I'm trying to use Imagemagick to "polygonize" an image. To illustrate what I mean here's an example made with G'MIC. Original photo: https://www.catster.com/wp-content/uploads/2018/07/Savannah-cat-long-body-shot.jpg End result: https://i.imgur.com/rW8qw2t.jpg An explanation of how the G'MIC script ...

So, I worked out what was the "problem". Since either a later version of Imagemagick 6 and/or Imagemagick 7 the code is more strict. in `'u[floor(15.9999*u)+1]'` the 15.9999 refers to the number of input images to use for the repeating tiles, which in dpat_symbols.gif is 16. If the number of input ...

I've tried a few things and it seems that, at least on Linux, the issue with that one specific command is the "+1". If I run the following command it seems to work (or at least not crash).
Still no idea why this exists on Ubuntu/Linux and not other OS's.

Still the same error. I'm guessing this error is specific to Linux/Ubuntu Linux but I can't figure out what could be causing it.

Just tried this on a fresh install of Ubuntu 18.10 and still the problem occurs. I really can't tell where the problem lies.

Post has been edited to link to input images.

I'm attempting to use the fx command on an image. In particular I'm attempting to run the example from here: http://www.imagemagick.org/Usage/quantize/#diy_symbols Input images: [*] eyes.gif http://www.imagemagick.org/Usage/quantize/eyes.gif [*] dpat_symbols.gif http://www.imagemagick.org/Usage ...

Thanks for that, although I don't necessarily want to render the whole drawing, just a specific area different from the area already set within the SVG file.

Post your SVG file so others can test with it. Can you not just edit the SVG file to change the bounding box? I'm away from my main computer at the moment but can't attach it but here are another set of SVGs where I have the same problem. https://www.dropbox.com/s/mjj7yq2xcnfkkhi/svgs.zip?dl=0 I ...

I have a folder of SVG files containing artwork generated automatically via a script. Objects within that file sit outside of the canvas size. An example is below. It's a screenshot from Inkscape and so the black line just shows the size of the canvas. https://i.imgur.com/HaeQMqB.png I want to use ...

I do not believe Imagemagick supports APNG only MNG That's interesting! I converted all of the files to apng by running for file in *.gif ; do convert $file ${file%.*}.apng ; done I ran identify on one of the files and it returned this: email.apng[0] GIF 55x60 55x60+0+0 8-bit sRGB 256c 24.6KB 0 ...

I'm using ImageMagick 6.9.7.4 on Ubuntu 17:10. I'm trying to convert a folder full of .gifs to .apng files. I'm doing this by running mogrify -format apng *.gif . However, when I run this I get the following error: mogrify-im6.q16: unable to open image `apng:': No such file or directory @ error/blob ...

Thank you! That's exactly what I needed.
