Hi I've noticed a number of problems with Sanselan's API:
1. There is a way to read files with multiple images (Sanselan.getAllBufferedImages()) but there is no way to write files with multiple images. This limits the usability of all multi-image file formats. 2. There needs to be a way to configure writing better (for example, the purpose of the different images in multi-image formats is often to store different color depths in one icon file, so there should be a way to configure what depth each image gets written in). 3. There is heavy confusion between per-image info (eg. width, height, bpp) and per-file info (format, MIME type, number of images in total) in the ImageInfo class. getImageSize() also doesn't fit multi-image formats - which image's size is being queried? Microsoft's Windows Imaging Component solved the problem by having an IWICBitmapDecoder, with methods GetFrameCount() and GetFrame(index) (see http://msdn.microsoft.com/en-us/library/ee690086(v=VS.85).aspx). The bitmap decoder can be queried for properties of the entire image file, while each frame can be queried for properties of that individual image. Sun's javax.imageio has something similar. How much can I refactor Sanselan's classes? Does any backward compatibility need to be maintained (since it's not at version 1.0 yet)?
