hi,
i'm trying to port a former jitter patch to pd/gem (http://lists.puredata.info/pipermail/pd-list/2006-11/043853.html). i have problems getting overlayed images to display properly. i have four rectangles fed by pix_movie, then i need to fade in and out a rendered text image. i tried using pix_image -> pix_texture and [alpha 1]. the images are .png with transparent portions. i once got it to display correctly, but now if i open the patch, the videos all show up with wrong colours:
http://sciss.de/test/Bild%201.png (see attached patch gemTest2.pd)
once i remove the pix_image and pix_texture, save the patch and re-open it, the videos show up correctly again:
http://sciss.de/test/Bild%205.png (see attached patch gemTest2B.pd)
... also, i don't know how to fade in the text (the "action" string). is there an alpha-channel multiplier for pix_image? thanks for hints!
is it possible to stretch the video so that the rectangle stays the same, but only the top part of the video is shown (vertically zoomed without interpolation, so that you can see the pixels)?

What OS and GEM version?
On OSX the pix_film/movie object defaults to YUV. Send a 'colorspace RGBA' message to the object before loading the clip if you need the alpha from the clip. pix_image uses RGBA by default. If you have problems with PNG the try uncompressed or TIFF.
Also, put the alpha object after the pix_objects.

hi,
i'm on osx 10.4 intel with pd-0.39.2-extended-test7, gem says "GEM: ver: 0.91-cvs", "GEM: compiled: Jan 5 2007".
the wrong colours appear equally when using TIFF images. to which object should i send the colorspace message? if i put it into [pix_movie], i get:
"error: pix_movieDarwin: no method for 'colorspace'".
interestingly, if i remove all the [pix_texture] objects and use [pix_draw] instead, the colours are displayed correctly (only i'm worried since the help says pix_draw is very slow compared to pix_texture, and i need to draw lots of CPU for audio later on).
also, if i use [pix_draw] instead of [pix_texture], i am able to use [pix_mix] (doesn't work with pix_texture?), so i can crossfade to a totally transparent picture, which does almost the fade-in/out i want. however, the pixel mixing is strange: the image becomes white before it's faded out. that is, pix_mix seems to to be assuming something like "alpha premultiplied", like stolidly multiplying each channel separately and not using alpha information for R/G/B multiplication:
http://sciss.de/test/Bild%203.png (you see the background of the text in the second screen from the left has gotten white instead of staying black ; this is the patch "gemTest2G.pd", using this transparent image : http://sciss.de/test/transp.png)
last not least, the images appear 180 degrees rotated when using pix_draw instead of pix_texture (see also Bild 3.png)

For what it's worth, I think that the color effects on 'Bild 201.png' look pretty sweet.

thanks, cyrille for your patch. yes mine looks chaotic but that's because i'm justing testing until i know everything works, before pasting that into the real patch.
unfortunately i have the same problem with your patch (psychedelic colours). the [colorRGB] is pretty cool, it does exactly what i want, but this only works here with [pix_texture] but have no effect when using [pix_draw] instead...

hi,
i'm trying to port a former jitter patch to pd/gem
(http://lists.puredata.info/pipermail/pd-list/2006-11/043853.html).
i have problems getting overlayed images to
display
properly. i have four rectangles fed by pix_movie, then i need to fade in and out a rendered text
image.
i tried using pix_image -> pix_texture and [alpha
1].
the images are .png with transparent portions. i
once
got it to display correctly, but now if i open the patch, the videos all show up with wrong colours:
http://sciss.de/test/Bild%201.png (see attached patch gemTest2.pd)
once i remove the pix_image and pix_texture, save
the
patch and re-open it, the videos show up correctly again:
http://sciss.de/test/Bild%205.png (see attached patch gemTest2B.pd)
... also, i don't know how to fade in the text
(the
"action" string). is there an alpha-channel
multiplier
for pix_image? thanks for hints!
is it possible to stretch the video so that the rectangle stays the same, but only the top part of
the
video is shown (vertically zoomed without interpolation, so that you can see the pixels)?

ok, it works now. i have to add all the paths containing [pix_texture] objects _after_ the GEM window has been created. that is, exclude them initially with a closed [gate], create the window, then open the gate. strangely, then everything's painted correctly. ...so i can use texture + colorRGB, nice.
thanks for your help + patience. ciao, -sciss-

i dont really understand but here is small advice : use spigot instead of gate (pd internal), don't use spigot , but send a 0 to gemhead.

ok, it works now. i have to add all the paths containing [pix_texture] objects _after_ the GEM window has been created. that is, exclude them initially with a closed [gate], create the window, then open the gate. strangely, then everything's painted correctly. ...so i can use texture + colorRGB, nice.
thanks for your help + patience. ciao, -sciss-

thanks, cyrille for your patch. yes mine looks chaotic but that's because i'm justing testing until i know everything works, before pasting that into the real patch.
unfortunately i have the same problem with your patch (psychedelic colours). the [colorRGB] is pretty cool, it does exactly what i want, but this only works here with [pix_texture] but have no effect when using [pix_draw] instead...

hi,
i'm trying to port a former jitter patch to
pd/gem
(http://lists.puredata.info/pipermail/pd-list/2006-11/043853.html).
i have problems getting overlayed images to
display
properly. i have four rectangles fed by
pix_movie,
then i need to fade in and out a rendered text
image.
i tried using pix_image -> pix_texture and
[alpha
1].
the images are .png with transparent portions. i
once
got it to display correctly, but now if i open
the
patch, the videos all show up with wrong
colours:
http://sciss.de/test/Bild%201.png (see attached patch gemTest2.pd)
once i remove the pix_image and pix_texture,
save
the
patch and re-open it, the videos show up
correctly
again:
http://sciss.de/test/Bild%205.png (see attached patch gemTest2B.pd)
... also, i don't know how to fade in the text
(the
"action" string). is there an alpha-channel
multiplier
for pix_image? thanks for hints!
is it possible to stretch the video so that the rectangle stays the same, but only the top part
of
the
video is shown (vertically zoomed without interpolation, so that you can see the pixels)?

i hope i can clarify this a bit in my own (maybe not too correct) words. there are actually two different domains in Gem: opengl and 'pix'es. all opengl-based stuff is renderend on the gpu (graphic card's cpu), whereas all pixel-based objects are calculated on the cpu. playing and processing videos and pictures happens in the pix-domain (afaik, all pix_*-objects work in that domain). pix_texture is used to convert an image (from a picture or a video) to a texture, that can be applied to a vertex . that means the picture is then in the opengl-domain and cannot be processed with pix_*-objects anymore. so there are actually two (or more?) ways of alpha-blending a picture:
- do everything in the pix-domain and use [pix_alpha] (i'm not quite
sure anymore about that) 2) give it to the opengl-domain using [pix_texture] and use the fourth (alpha-channel-)inlet of [colorRGB]. the latter approach has the advantage, that everything is rendered on gpu, which saves you a lot of cpu-power. whenever you can, i would do stuff in the opengl-domain (unless you don't have any 3d-acceleration enabled).
i hope i didn't tell you something completely wrong (please someone correct me, if i did)

ok, thanks for clarification.
but what about pix_movie, it seems to be in another domain than pix_image because i cannot apply the processes to it that i can apply to pix_image. also pix_image "needs" either pix_draw or pix_texture -> pix_rectangle, while pix_movie goes directly into pix_rectangle without an intermitting pix_texture, and it cannot be plugged into pix_draw ...?

but what about pix_movie, it seems to be in another domain than pix_image because i cannot apply the processes to it that i can apply to pix_image.
this is because [pix_movie] has [pix_texture] already 'built-in'. the equivalent to [pix_image] would be [pix_film], which requires an extra [pix_texture] to be textured onto a 3d-object.
also pix_image "needs" either pix_draw or pix_texture -> pix_rectangle,
yes (though i think you mean [rectangle] here instead of [pix_rectangle], which does something different).
while pix_movie goes directly into pix_rectangle without an intermitting pix_texture, and
yes (also here i assume you mean [rectangle])
it cannot be plugged into pix_draw ...?
exactly, because [pix_draw] wants a pix, not a texture.

i hope i can clarify this a bit in my own (maybe not too correct) words. there are actually two different domains in Gem: opengl and 'pix'es. all opengl-based stuff is renderend on the gpu (graphic card's cpu), whereas all pixel-based objects are calculated on the cpu. playing and processing videos and pictures happens in the pix-domain (afaik, all pix_*-objects work in that domain). pix_texture is used to convert an image (from a picture or a video) to a texture, that can be applied to a vertex . that means the picture is then in the opengl-domain and cannot be processed with pix_*-objects anymore. so there are actually two (or more?) ways of alpha-blending a picture:
- do everything in the pix-domain and use
[pix_alpha] (i'm not quite sure anymore about that) 2) give it to the opengl-domain using [pix_texture] and use the fourth (alpha-channel-)inlet of [colorRGB]. the latter approach has the advantage, that everything is rendered on gpu, which saves you a lot of cpu-power. whenever you can, i would do stuff in the opengl-domain (unless you don't have any 3d-acceleration enabled).
i hope i didn't tell you something completely wrong (please someone correct me, if i did)

pix_movie directly textures the image. On OSX it uses some tricks to improve performance when dealing with HD resolution clips. I will have a look into the 'colorspace' issue although I will say that RGB isn't the most efficient path to use.
