Non uniform matrix

Hi,

Would it be possible to animate something with the presence of “ghost pixels”? Not sure what they

would be called.

Basically I have a rectangular led screen, but in the middle of the screen is an area where no pixels would

be present. But I need allpixelmini or bibliopixel to treat the driving of the leds as if they were there, so the

animations dont get messed up.

ive attached a crude picture of what im designing.

Thanks

It’s possible, but you have to specify the coordinate map manually, like this project.json file:

    {
"driver": {
"num": 12,
"typename": "serial"
},
"layout": {
"typename": "matrix",
"width": 4,
"height": 4,
"coord_map": [
[0, 1, 2, 3],
[4, -1, -1, 5],
[6, -1, -1, 7],
[8, 9, 10, 11]
]
},
"run": {
"fps": 30
},
"animation": "BiblioPixelAnimations.matrix.bloom"
}

This would take 12 pixels and turn them into a 4x4 matrix, with a 2x2 hole in the middle. -1 “ghosts” a pixel
Sadly, no quick way to do this without just building the matrix manually.
