Trying to split the two issues.

Default font issue

Does montage work without error, if you add -font Arial or some other font? If not, then perhaps your freetype is flawed or outdated.

If I specify a font that is available in
convert -list font
then it works without warning. (Arial is ...

Using montage triggers a warning or error:

$ montage a.jpg b.jpg test.jpg
montage: unable to read font `(null)' @ error/annotate.c/RenderFreetype/1316.

The image output seems fine but the command line output still seems strange.

$ montage --version

Hello, I'm getting what looks like OpenCL errors:

$ convert -size 99x99 caption:"t" -border 1x1 t.png
convert: clBuildProgram failed. (-11) @ warning/opencl.c/CompileOpenCLKernels/1097.
convert: clCreateCommandQueue failed. (0) @ warning/opencl.c/InitOpenCLEnvInternal/1424.

I only noticed the ...

Thanks, fmw42. As you suggested, I did the following:

find /usr/share/fonts/ -type f \( -name "*.ttf" -or -name "*.otf" \) > fonts

IFS=$'\r\n' content=($(cat fonts))

rm -r fonttestout
mkdir fonttestout

for ((idx = 0; idx < ${#content[@]}; idx+=1)); do
font="${content[idx]}"
name=`basename ...

Thanks!

Looks like my Linux installation uses Type1 by default (/usr/share/fonts/Type1/n019003l.pfb)

This command returns many lines. Not sure if this is significant. Makes the ...

The character exists, I checked with
convert -background black -fill white -size 100x100 -gravity center label:"Åker" check.png

The \n method (inserting newline at beginning of each string) sounds good but might make space use very much less optimal. In my case ...

Hello,

I'm trying to fill a certain area with variable text that will generate line breaks / word wrap. So I need captions. The variable text can contain all kinds of international names and titles.

Unfortunately, for example in "Å", the circle gets cut off.

convert -background black -fill white ...

Hello,

Running the following command should create an image with evenly red semi-transparent background color, right?

convert -background '#ff0000aa' -fill white -pointsize 72 -bordercolor '#ff0000aa' -border 40x20 label:"TEST" test.png

However, according to GIMP , the inner red has an alpha ...

Suggestion, see if it happens if you use some other compression method. Also is there a smaller limited number of input files that work?
Thank you for suggesting this!

To clarify, the command can be used to get a string like for example 'sRGB' or 'Gray' with no newline ending.

As far as I followed this thread, 6.8.5-7 still had issues.

In IM6 r12270 on Arch Linux 64bit, the spacing seems to work for me. See below for an explanation why the font family is different.

It seems to be impossible for me to convince you that I understand this?
