Hey there!
I'm new here. I've been playing around with vips to generate images and I'm having super fun to be honest. I've ported all I had from imagemagick and it's loading way faster, so I'm pretty happy with that.
However, I'm getting this error when trying this annotate example if I change the text left corner by left & corner, in the 7th line.:
/Users/tavo/.asdf/installs/ruby/3.1.2/lib/ruby/gems/3.1.0/gems/ruby-vips-2.1.4/lib/vips/operation.rb:228:in `build': text: invalid markup in text (Vips::Error)
from /Users/tavo/.asdf/installs/ruby/3.1.2/lib/ruby/gems/3.1.0/gems/ruby-vips-2.1.4/lib/vips/operation.rb:483:in `call'
from /Users/tavo/.asdf/installs/ruby/3.1.2/lib/ruby/gems/3.1.0/gems/ruby-vips-2.1.4/lib/vips/image.rb:234:in `method_missing'
from test.rb:7:in `<main>'
As you can see in those logs, I'm running ruby 3.1.2 and ruby-vips 2.1.4 (vips-8.12.2)
Do I need to scape or encode or something that parameter?
Thanks in advance!

Hi @luctus,
The text operator supports pango markup, so yes, you need eg. &. You'll need to escape < and > as well.

Thanks a lot, @jcupitt !
So, just to confirm... instead of this:
left_text = Vips::Image.text "left & corner", dpi: 300
I should be using this:
left_text = Vips::Image.text CGI.escapeHTML("left & corner"), dpi: 300
I just tested it and it worked ;)
