jit.expr to jit.gen
Hello Friends,
I am trying to figure out how I could replace the following expression:
[jit.expr @inputs 3 @expr "in[0].p[0]*in[1]" "in[0].p[1]*in[2]" "in[0].p[2]*in[2]" "in[0].p[3]*in[2]"]
I use it to apply different transformations on Aplha channel (p[0]) and RGB channels (p[1], p[2], p[3]). I use this for a Soft Edge patch.
Thank you very much for your help.
Happy New Year, Happy Maxing!

You can use swiz to access the plane of a matrix cell just like .p[0] in jit.expr. Here’s an example. Don’t forget that in jit.pix, the color format is RGBA just like in jit.gl.pix, which is different than the usual jitter matrix format of ARGB.
Hi Wesley!
Thank you very much for the patch!
I did not know the [concat] object.
I was on the track with C74 Expo Gen Patches, but I did not read anything about [concat].
Is there a extensive list of [gen] objects somewhere?
Again, thanx very much

If you search for Gen in the documentation, you’ll pull up a bunch of reference material on Gen, GenExpr and the various operators. concat was recently added and slipped through being documented. As far as I know, it’s the only undocumented operator.
