I'm brand new to Jitter and I have a couple of questions.
First, some background. Having had past experience with applications like Adobe Photoshop and After Effects, I'm used to creating composite images from layers. I know that if I place one layer over another, then provided the upper layer has a transparency layer, I'll be able to see parts of the lower layer beneath it.
I'm now trying to apply this concept to Jitter. My progress is in this patch:
I have two matrices of 10 by 1 pixels.
The matrix on the left is filled with white pixels, all of which have their alpha channel to 255 (full opacity). In Photoshop terms, this could be seen as my image background.
The matrix on the right has pixels alternating between completely transparent (alpha of 0) and fully opaque red. In Photoshop terms, this is like my first layer that I will place over the background.
Now I want to lay the right matrix over the left matrix, and thus the resulting image would be pixels alternating between white (the background) and red (the first layer).
The closest to this I have achieved is using [jit.op @op -], although as you can see from my patch this isn't quite right. (The cyan colour is unexpected, and it requires two bangs into each source matrix to get it.)
So my first question is: can/should Jitter be used in this way? Or do I need to get my head out of Photoshop world and into another way of thinking?
Secondly, if I am already on the right track, then is it jit.op that I should be using for this? And if so, which operator is the correct one to use?
Many thanks in advance to any experienced Jitter heads who can help me on my path into Jitter :)
