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?
Cheers,
tim

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].

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!

afaik, the work on solving these problems is in progress (if not already solved yet). try the newest auto builds

your welcome!

why does it seem like a hack to you? if you want to create an avi of your car, you have to use a video-camera. if you want to create an avi of (vector) graphics, you have to render them into pixel space.
i don't think that either of these is a hack; it is just how things are done.
hack or not, i think there is no other way, unless there are plans for something like a [pix_text].
definitely not. if you don't want to do graphics but video instead, you are problably better off with pdp.... (this is not meant as an insult on you or pdp; it is just that pdp (apart from 3dp) is video/pixel oriented instead of graphic-oriented; yves has done a [pdp_text])
however, "exporting" to different formats should be made simpler in Gem...

This may be an option for OS X users soon, after sufficient pdp/pidip testing is done with Pd-extended!

that is what i actually expected ;-)

i could live well with that. the problem i have is, that i can use [pix_snap] and i can also use [pix_record], but when i try to record the grabbed framebuffer (use both at the same time), my pd/gem crashes :-(
