Flip pixels after `gl.readTexture`:
|
|
|
|
```js
|
|
var flip = require('flip-pixels')
|
|
|
|
var w = gl.drawingBufferWidth;
|
|
var h = gl.drawingBufferHeight
|
|
var pixels = new Uint8Array(w * h * 4);
|
|
gl.readPixels(0, 0, w, h, gl.RGBA, gl.UNSIGNED_BYTE, pixels);
|
|
|
|
flip(pixels, w, h)
|
|
```
