Probably text is not supported by wasm-IM but just in case I wanted to track this limitation here and make sure so we can update README with this information. Thanks

Researching I see that for text support ImageMagick must be linked with libfreetype which is currently not. We should document which features are not supported (like this one).

Besides that I tried to add the library and I'm not sure if it was inked but each time I try to print text it seems that ImageMagick try to call the program gs (ghostscript I think) - so even if the library is linked OK I doubt it will work. But I'm not an expert with emscripten so I'm not 100% sure of this...

[cancerberoSgx]

It's now explicitly documented in readme that this is not supported, so I'm closing this

[cancerberoSgx]

Since I think this is an important ImageMagick feature and since emscripten supports freetype library as a port (-s USE_FREETYPE=1) and I will try to make it work and since I will try to make it work I'm reopening this issue to track the work here.
