Is there a way to apply the pixellate filter on a vignette filter using the GPUImage library?

I am trying to achieve an effect that includes a GPUImage vignette filter + a pixelate filter as well, but it looks like the vignette is not pixellated.

Probably the reason is why it doesn't pixellate the vignette, because the vignette filter is not a blend filter.

Apart from the short answer - "no, it's no possible", do you know any workaround how to achieve this effect?

Thanks a lot in advance

Solution

  • No, it is possible :)

    Option 1: try filter groups with both filters. You can find the docs for the Filter Groups on Github page of GPUImage lib.

    Option 2: if you are processing image, apply vignette filter to the image, get the result image, apply pixellate filter to the result image.

    Hope this helps.
