<FONT COLOR="#000000">hi,</FONT>
<FONT COLOR="#000000">i'm trying to port a former jitter patch to pd/gem</FONT>
<FONT COLOR="#000000">(<A HREF="http://lists.puredata.info/pipermail/pd-list/2006-11/043853.html">http://lists.puredata.info/pipermail/pd-list/2006-11/043853.html</A>).</FONT>
<FONT COLOR="#000000">i have problems getting overlayed images to display</FONT>
<FONT COLOR="#000000">properly. i have four rectangles fed by pix_movie,</FONT>
<FONT COLOR="#000000">then i need to fade in and out a rendered text image.</FONT>
<FONT COLOR="#000000">i tried using pix_image -> pix_texture and [alpha 1].</FONT>
<FONT COLOR="#000000">the images are .png with transparent portions. i once</FONT>
<FONT COLOR="#000000">got it to display correctly, but now if i open the</FONT>
<FONT COLOR="#000000">patch, the videos all show up with wrong colours:</FONT>

<FONT COLOR="#000000">(see attached patch gemTest2.pd)</FONT>
<FONT COLOR="#000000">once i remove the pix_image and pix_texture, save the</FONT>
<FONT COLOR="#000000">patch and re-open it, the videos show up correctly</FONT>
<FONT COLOR="#000000">again:</FONT>

<FONT COLOR="#000000">(see attached patch gemTest2B.pd)</FONT>
<FONT COLOR="#000000">... also, i don't know how to fade in the text (the</FONT>
<FONT COLOR="#000000">"action" string). is there an alpha-channel multiplier</FONT>
<FONT COLOR="#000000">for pix_image? thanks for hints!</FONT>
<FONT COLOR="#000000">is it possible to stretch the video so that the</FONT>
<FONT COLOR="#000000">rectangle stays the same, but only the top part of the</FONT>
<FONT COLOR="#000000">video is shown (vertically zoomed without</FONT>
<FONT COLOR="#000000">interpolation, so that you can see the pixels)?</FONT>
<FONT COLOR="#000000">ciao, -sciss-</FONT>
