I want to create a control that will let me edit a 

matrix of size 256x256. I need to be able to zoom in 

and do fine detailed editing. Being from the MSP world,

I am not familiar with all the jitter work that has been done.

Does anyone have a patch/control that allows me to zoom in a 

edit a matrix? If not how would I go about doing this?

maybe something like this... basically just the jit.cellblock helpfile hacked for my purpose.

Thanks Tyler, I already tried jit.cellblock and matrix control.

They work pretty well for small matrices but if you are 

working on something that is 256x256, things get really hard to

see. The matrix values are basically pixels that I am setting 

to form a picture. I really need something that lets me zoom in 

I was thinking I could use photoshop to create jpegs and then

load them into Max. But it would be nice to be in the same

ji.submarix is your friend to zoom in / view parts of your 256x256matrix. you can easily edit the content of this submatrix using jit.operators ( jit.op ) depending on what you have in mind.

for starters ( reload to activate [loadbang] ) :

Wow, this gets me most of the way there.

Thanks karrrlo!


hey nice k. This would be sweet for a gui interface for referencing a portion of a high res image.

Nice example. Here is a slightly modified version which use 

jit.pwindow mouse tracking to position the rectangle.

you are welcome,some enhancements need of course to be brought, it is one among other solutions, all you need is to reinject the copied/procesed matrix into the right place.

which is a little more tidious, maybe somebody else could chime in :)

may i ask what you are planning to do ? the purpose is probably musical (?). with more info we could be of beter help :)

Wetterberg shared a few patches a while ago, more based on slit scanning, using matrices for score editing.

Yes, it is a music application. I have been experimenting 

with csound's scanned synthesis. As input, it takes a matrix

that represents a network of mass springs. I wanted

to create a matrix editor that would allow me to easily 

The next step would be to edit individual pixels. Does

jit.matrix and submatrix support setting individual pixels?

Couldn't resist joining the fun:) Here's an addition that changes

zoomed part of the original matrix:

Those are great! I couldn't resist putting in my two cents as well. This one uses the function generator to extend the patterns, has an image loader, and lets you use coloration with a ramp time. (The "apply" button for scale/bias doesn't work with the function, though, since it's always updating.) Try fiddling with the various function controls, there are some really nice patterns and forms you can create using the dropdown and the scale/offset etc. (noise.voronoi is my favorite, see pic.) Maybe these will be useful for the eventual music elements too.

Still don't have a way to easily edit individual cells, but it shouldn't be too tough, and it's already well past my bedtime. Ah, the forum---causing sleeplessness yet again....!

Hey you guys, thanks for all the help. Here is my 

version with pixel editing functionality added...

Ooops made a mistake, this should work better...
