Support inSampleSize and decoding region like Android's BitmapFactory and BitmapRegionDecoder

[panpf]

I am developing image loading framework and image scaling components for kotlin multiplatform. I need a cross-platform image decoding library that supports decoding region and downsampling, similar to the functions of BitmapFactory and BitmapRegionDecoder in Android. Skiko's Image currently only supports full decoding of images.

Are there any plans to provide decoding region and downsampling support?

Do you know if there is such a feature in skia?

Since skiko is a kotlin wrapper for skia, it provides a subset of APIs available in skia.

I would like to see that feature, too.

What I found so far is this:
https://github.com/google/skia/blob/main/src/codec/SkSampledCodec.h

I don't know if this works in general or only for Android.
