So, as the title says, my task is to convert a given phrase to an image on server side (php GD) with a selected .otf font. The phrase can include not only latin characters but also greek and cyrillic.
PHP's imagettftext (http://php.net/manual/en/function.imagettftext.php) won't work with non-latin characters on .otf fonts (works ok with .ttf as it seems).
Any clues?
EDIT: Font needs to be .otf
Posting rough answer that seems to work for future people bumping on this post:
Solution seemed to be: 1) open OTF with LATEX server side 2) produce PDF 3) convert to image with ImageMagick library.
