Haxe

because that would cause lag since im doing it on a video

We need more info on what you're trying to do

image

if so, you can draw it to a smaller bitmap, once and display that, if not you should use a shader

can you show me how to draw it into a smaller bitmap if you are okay with it

https://api.openfl.org/openfl/display/BitmapData.html#draw

you'd call draw on the new smaller bitmap, with the larger bitmap as the source

and you'd use a matrix to scale the image down
https://api.openfl.org/openfl/geom/Matrix.html#scale

it works when I do it, what does "not  working" mean to you

i should also mention that you need to use the new bitmap in a flxsprite and scale that sprite back up

```lua
        var resMtx = new Matrix();
        resMtx.scale(0.4, 0.4);

        var resBmp = new BitmapData(200, 200);
        resBmp.draw(originalBitmap, resMtx);

        resSpr.pixels = resBmp;
```

also when i was messing around with set/getPixel32 i made this on accident which looks cool

but also, if you're doing this opperation on an update loop you should look into shaders, this kinda thing is pretty simple in shaders, but for a one-time static image a cached graphic is best
