PNG image compression options


The docs list all the available parameters for image resizing, compression, quality, density, etc. (http://docs.grabaperch.com/docs/templates/attributes/type/image/)

Which of these can also be applied to PNG images that make use of transparent backgrounds?

My install uses: Image manipulation: GD Imagick

I don't believe the quality attribute is used for PNGs, as it's controlling the lossiness of the compression, and PNG is lossless.

That's what I suspected. Just wondered if it perhaps ran it through some kind of PNG optimization.
