Ultra high res image support
Very high resolution images are resulting in new requirements for managing and analyzing image data. Fields including bioinformatics (e.g. electron microscopy; linkage disequilibrium), art, and remote sensing are turning to HDF5 because it has the basic ability to handle large images. This work would expand HDF5 image support to dealing more efficiently with very high res raster images, such as images with 100K or more scan lines. Capabilities could be added such as multi-resolution support, progressive image transmission, new compression methods, and alternate linearization patterns like space-filling curves. HDFView would be enhanced to better support image panning and zooming, and could add filters to improve visualization of high-resolution data on limited-resolution devices. This may also be a good place to add new image features such as region annotations. (See also "Medical image data management.")
