@Igor Thanks for the aclaration, I am quite new to pharo and I just wanted to help with what I've seen
No problem. I need to finish that thing.. the dilemma there is that supporting old fashing text rendering is not going to show good results. Writing a new text support + layout is another piece of work, we're just started.. but it if far from finishing. But do not confuse: you can render strings with any truetype font using Athens, but what you cannot do is to use it for rendering TextMorph(s) contents. Because TextMorph is heavily hardcoded for using balloon canvas.. with lots of optimizations and complexity.

Thanks Igor. That was exactly what I was looking for.

I need to improve the performance of a lot of text that drawn on screen while the screen is being dragged around and would like to experiment with rendering the text to a bitmap buffer then painting that onto a canvas. How might that be achieved? And from Workspace can I test this? I have been searching for a couple of hours already so thought I'd just ask.
easy.
form := Form extent: 100@100 depth: 32.
canvas := form getCanvas. canvas drawString... whatever.
and then:
displayCanvas drawImage: form.
cheers -ben
