Convert and Pango Issues

[Jeremy]

I'm attempting to run a convert command from the command line. The font I'm using has ligatures so I need to use pango. However pango doesn't seem to want to work or recognize the font where label or caption does. My command is:

convert -font test-Regular.ttf -pointsize 124 PANGO:"ac" pango.png - doesn't work

convert -font test-Regular.ttf -pointsize 124 label:"ac" label.png - works

When I run convert -version I get:

Any ideas?

Thanks!

Where can we get test-Regular.ttf to test? If that is a custom font, the please post a link to a copy of it.

Try specifying the font inside the PANGO markup language. See https://imagemagick.org/Usage/text/#pango

Check your pms

Sorry, I am not having any success either with your font and Pango.

I tried:

Code: Select all

convert -font jeremy-Regular.ttf -pointsize 124 PANGO:"ac" pango.png

and

convert PANGO:'<span font="jeremy-Regular.ttf" size="126976">ac</span>' pango.png

and

convert -font jeremy-Regular.ttf -pointsize 124 PANGO:"@test.txt" pango.png

where test.txt was a UTF-8 compatible text file contains and showing your actual characters.

Using IM 6.9.10.24 Q16 Mac OSX.

However, this works:

Code: Select all

convert -font /Library/fonts/jeremy-Regular.ttf -pointsize 124 CAPTION:"@test.txt" pango.png

Yeah maybe I made the font wrong. I'm going to take a closer look at it. I'll report back once I find out anything out. Thanks for your help!

As far as I know, pango needs the font to be installed at the system level, rather than simply using a font file.

[fmw42]

Your font is fine. See my additional comment above and here. Put the text showing your characters in a UTF-compatible text editor file and then specify the file in the CAPTION with the @ symbol as below. The following works for me.

Code: Select all

convert -font /Library/fonts/jeremy-Regular.ttf -pointsize 124 CAPTION:"@test.txt" pango.png

See https://imagemagick.org/Usage/text/#unicode

[Jeremy]

Alright, I'm narrowing it down, I think Pango isn't installed right as it doesn't seem to work with any fonts at all for me.

[fmw42]

Did you follow my command using CAPTION? Did that work? You should not need PANGO as CAPTION does work if you specify a UTF-8 compatible text file with your text in your actual font.

Note snigbo's last comment about installing fonts into the System.

[Jeremy]

Caption didn't really work for me and PANGO doesn't seem to work with Imagick. I need to spend sometime digging into convert and exec.

[fmw42]

To use CAPTION properly, you need to put your text into UTF-8 compatible text file that shows your characters properly. Then use @textfile.txt to load that text into CAPTION. See the link I provided.

[Jeremy]

Thanks!

Anyway this works:
convert PANGO:"<span font_family="jeremy" size="126976">ac</span>" pango.png.

It doesn't however seem to work from a PHP exec. I'm sure I'm just missing something small.

[fmw42]

PHP uses different environment variables than your OS. So you might try putting the full path to convert in your exec() command
