pyramidtiff

Overview

pyramidtiff is a command line tool which takes an image file (jpg, tif, png or bmp) and creates a multi resolution tif file with tiles. Such tif files can be used by high resolution image viewers like iipimage to quickly zoom into huge images.

The new tif contains the original image, the image scaled to half the width and height, the image scaled to quarter width and height and so forth. Each image is saved in tiles and compressed with the Deflate (zlib) algorithm. These are basic TIFF features, so any tiff viewer can show the image.
