TIFF files from pix_buffer (and others?) missing some "standard" tags?
by B. Bogart 06 Aug '10

06 Aug '10

Hey all, I've had trouble loading some TIFs generated in pd/Gem in PIL (python imaging). I asked on the list and it seems PIL expects some particular TIF tags being set in order to recognize the image. I think it can only be an improvement to add these tags so that tifs generated in pd/Gem can be loaded by as many applications as possible. The attachment contains the specific tags. Thanks, B. Bogart

please always reply to the list. Conor Higgins wrote: > sorry i incorrectly phrased the error.... > > well i am using those bridges but to no avail....thats why I am looking > for help... I already knew about the different libraries etc... then you have to re-phrase your problem. you say that you get the "error: pdp_mgrid: no method for 'gem_state'". this means exactly, that you are putting a pdp object into a gemchain directly. something like [pix_video] | [pdp_mgrid] whereas you should use [pix_video] | [pix_2pdp] | [pdp_mgrid] fgmasdr IOhannes

Hi all, I have a quick question...I am trying to get from pix_video to pdp_mgrid to monitor the motion of the live input stream... however i keep getting this result: error: pdp_mgrid: no method for 'gem_state' Has anybody got an idea why I might be getting that? Conor

pix_buffer feature request
by B. Bogart 20 Nov '08

20 Nov '08

Hey all, I'm using a buffer in random access order, so there tend to be empty slots. Rather than just printing to the console "empty slot" it would be nice to handle the state of buffer slots from inside PD. in particular pix_buffer_read could have an additional outlet which would send a "1" when the index corresponds to a occupied slot, and "0" when the index corresponds to an empty slot. Perhaps pix_buffer could have a message for querying the state of the buffer slots "empty 0" to check if slot 1 is empty. What I have done is load black images into all slots before writing in order to avoid the lacking texture square. It would be better for the gemhead just not to render if its slot is empty. See you in Bergen Johannes! Thanks, B.

For example you want to init a pix_buffer with all black images: open black.tif 0 # load the image into first slot from disk. copy 0 1 # copy image from first slot into second (from memory, so its fast.) ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=507082&aid=2235817&group_…

pix_video grabs with wrong resolution
by Max 06 Nov '08

06 Nov '08

hi list, i have this console output: [pix_videoDarwin]: height 320 width 240 [pix_videoDarwin]: SG channnel Device List count 4 index 1 [pix_videoDarwin]: SG channnel Device List DV Video0ﾀ [pix_videoDarwin]: SG channnel Device List IIDC FireWire Video [pix_videoDarwin]: SG channnel Device List QuickCam [pix_videoDarwin]: SG channnel Device List USB Video Class Video error: [pix_videoDarwin]: SGSetChannelDevice returned error -9408 ... you might be able to track this down from the Find menu. [pix_videoDarwin]: vdigName is iSight [pix_videoDarwin]: digitizer rect is top 0 bottom 1200 left 0 right 1600 [pix_videoDarwin]: active src rect is top 0 bottom 1200 left 0 right 1600 [pix_videoDarwin]: set SG NormalQuality [pix_videoDarwin]: using YUV in GEM: ver: 0.92.CVS GEM: compiled: Nov 3 2008 on OS X the problem is, that pix_video shows only a fraction of the image from the camera. just like a zoomed in part of the camera image. the resolution of the camera is height 320 width 240 (one of the old external isights) the lines: digitizer rect is top 0 bottom 1200 left 0 right 1600 and following seem to indicate that the size of the captured image would be huge. how can i get this right? m.
