Hi, I'm interested in the zif file format in order to create and visualize very large (800Kx5K pixels) zoomable images. The format seems to be based on a tiled big tiff spec, with tiles composed of jpeg or png images. I'm wondering, how much work do you think would be involved to implement encoders and decoders for the format based on the current state of support of tiff, jpg and png and the format spec listed on the linked page?
