So I am trying to display an Arabic word using ImageMagick.
This is my code:
convert -size 1144x800 -background transparent -font "arabic_reg.ttf" -encoding Unicode label:#arabic.utf8 "oops.png"
#arabic.utf8 is saved in utf-8 and arabic_reg.ttf is an arabic font.
This is the result
letters are detached and inverted
adding -direction right-to-left doesn't seem to help also.
I am running ImageMagick 6.9.6-2 on mac.

Any idea how to fix this?

Ran into the same problem, you gotta use pango and install the fonts in your system :)

My command was convert imagename.jpeg -quality 100 -modulate 100,200 imagename-ImageMagick.jpeg and if you look at the Imgur gallery here:
https://imgur.com/a/V8zr4Lu
you can see that it has tons of JPG artefacts, to the point where the text is almost illegible. All I wanted to do was increase colour saturation.

Because when you increase saturation that much you make the existing JPEG artifacts more visible (in fact you make all the image problems more visible...). Adding saturation is increasing the tone differences, while the JPEG compression is based on the idea that the tone differences it creates are still below your perception, so increased saturation makes the existing and barely noticeable artifacts suddenly very visible.
-modulate 100,200 is a very aggressive setting, try something lighter
-quality 100 is pointless, you are just saving existing artifacts with a high accuracy.
maybe try a very light blur before increasing saturation.
Using Imagemagick 6.9.12.77, it looks fine to me
convert galaxy.jpg -modulate 100,200,100 -quality 100 x.jpg
Perhaps you need to upgrade either or both Imagemagick or libjpg

I'm using a recent version of ImageMagick on Windows 10 to resize and compress .tif files with mogrify *.tif -resize 20% -compress lzw. The input files are all the same dimensions and weigh a few hundred to a thousand KB, but the output files are all the same size, around 138 MB. This suggests to me that the mogrified files are being stored uncompressed. Using mogrify *.tif -compress zip leaves the files at their inflated size.
Why is the compression step failing?
Output of magick -version:

The sequence of commands is important: success was obtained with mogrify -resize 20% -compress lzw *.tif.
According to the ImageMagick documentation, I would expect this:
convert fountain-pen1.jpg fountain-pen2.jpg handwriting.jpg -resize 400x400\> -set filename:f '%t_smol.%e' '%[filename:f]'
to result in fountain-pen1_smol.jpg fountain-pen2_smol.jpg handwriting_smol.jpg.
Instead, it only creates fountain-pen1_smol.jpg.
What am I doing wrong here?
I've also tried with just *.jpg which results in the same output.

Mmm... sometimes you need to give ImageMagick a hint to create more output files than it is expecting to, using +adjoin:
convert fountain-pen1.jpg fountain-pen2.jpg handwriting.jpg -resize 400x400\> -set filename:f '%t_smol.%e' +adjoin '%[filename:f]'
It guesses this if you put a %02d or somesuch in the filename, but doesn't know that for your use case.
With ImageMagick you'll generally need to set that "filename:" variable right after reading in the images. Try this...
convert img1.jpg img2.jpg img3.jpg \
-set filename:f "%[t]_smol.%[e]" -resize 400x400\> "%[filename:f]"
That reads in the images, sets those output filenames right away, then performs the resizing operation, then writes the output files with the given names. Be aware that changing the order of the list or the number of images within the command can create unexpected results.
I've used this command successfully with IM 6.8.9 in bash. It works with 6.9 and 7.0 versions in Windows by changing the continued-line backslashes "\" to carets "^", and deleting the backslash and putting the resize "400x400>" inside double quotes.
I'm trying to montage some semi-transparent icons into one image using imagemagicks montage tool.
Unfortunately, after every operation with alpha a bit of black is showing everywhere on anti-aliased edges.
For example, these two icons:
and
After issuing
montage 1.png 2.png -background none montage.png
Result in:
I've tried numerous combinations of alpha, background and changing option order and haven't found a way to prevent this. Any idea?
My system is windows 8.1+cygwin, montage version is:
$ montage -version

This looks like a version-specific bug, as the given command works fine on ImageMagick 6.9.1-10 and also using:
convert 1.png 2.png +append 3.png
When I run this:
/usr/local/bin/convert ~/desktop/myImage.psd ~/desktop/myImage.jpg
I get this error:
convert: no images defined `/Users/User/desktop/myImage.jpg' # error/convert.c/ConvertImageCommand/3230.

I am one on the developers of ImageMagick and this version contains a bug in the PSD reader. We are aware of this bug and it will be fixed in 6.9.1-8.
Upgrade to 6.9.1-8 to address the issue.
