> I needed larger icons of icns files, than currently extracted with the Apache Commons Imaging ICNS Image Parser/ICNS Decoder.
> So I edited the Source Code:
> In case an icns element is a PNG (depends on 0-4th byte [header]), 
> the bytes can be put in a ByteArrayInputStream and then read by ImageIO.read, that returns the BufferedImage needed.
> Then it can be added to the list of List<BufferedImage> in IcnsDecoder#decodeAllImages().
> InputStream in = new ByteArrayInputStream(imageData);       
> BufferedImage image =  ImageIO.read(in);
> To the enum IcnsType I added:
> ICNS_256x256_32BIT_ARGB_IMAGE("ic08", 256, 256, 32, false),
> ICNS_512x512_32BIT_ARGB_IMAGE("ic09", 512, 512, 32, false),
> ICNS_1024x1024_32BIT_ARGB_IMAGE("ic10", 1024, 1024, 32, false);
> https://en.wikipedia.org/wiki/Apple_Icon_Image_format
> No need for Rle24Compression.decompress() or decode32BPPImage().
> I can upload the code somewhere, please tell me how to do.
