First of all , thank you for your great work.
I've been trying to follow wobbling cat example but first I started by redrawing an image. I use nodejs and getPixels() method instead of getting a canvas. It all works fine with cat.jpg and other 1000 x 1000 images but when I use large (3634x5451) image this is what happened.
CODE
const kernel = function(image) {
let x = this.thread.x,
y = this.thread.y;
const n = 4 * ( x + this.constants.w * (this.constants.h - y) );
this.color(image[n] / 256, image[n+1] / 256, image[n+2] / 256, image[n+3] / 256)
}
const drawImage = gpu.createKernel(kernel)
.setConstants({ w: width, h: height})
.setOutput([width, height])
.setGraphical(true)
drawImage(buffer)
const pixels = drawImage.getPixels()
gpu.destroy()
// write image file with returned pixels
Running on
- NodeJS : 14.17.3
- gpu.js : 2.11.3
- jpeg-js : 0.4.3
- AMD Radeon Pro 5300M

It should just redraw the same image.
