Hi Roman,
Okay, I had contemplated this and though that it must be possible to do this easier. But No! This seems somehow like a hack, but I suppose pix_ things are there for image manipulation, not image creation...
I am using OSX so there is currently some problem with GEM and fonts and PD and...hmm... so it remains undoable anyway :->
But thanks: I will simply build a few simple graphical objects to transfer the information, then use pix_snap to get images for recording. Thank you muchly!

Hello List,
is there a way to get text into a pix chain?
my little "thing to do" is: a camera, some extra information into the camera stream (the text that I need), and record it using pix_record.
Or is there a better solution?
don't know, if there are various solutions, but you can convert the framebuffer into a pix again using [pix_snap]. either you can grab
both together, the video and the text, so that you display the text already upon the video, or you could grab the text separately (in a free
area of the gemwin) and use [pix_mix] to merge the text-pix and the video afterwards. the former is possibly simpler to implement, but since you are applying a pix as texture in order to display it in opengl and
then converting it back to a pix again, this might introduce interpolation artefacts. however, if you have alltogether in one pix, you can simply record it using [pix_record].roman
Cheers,
