PSD saver only compresses first layer

Post by ggarra13 »

When saving a multilayered PSD file, only the first layer is RLE compressed.

Also, it is not possible to turn on ZIP compression in the PSD saver. Setting ZipCompression ends up saving with None Compression.

We currently only support writing layers that don't have compression. The first layer is the 'merged image' that is a combination of all layers. It looks like we do support writing that with RLE but not the rest of the layers. I have no idea what that choice was made but we could change that behavior.

We don't support writing layers with ZIP compression at this moment we could add support for this in the future.

I have created an issue on Github about this: https://github.com/ImageMagick/ImageMagick/issues/84
