The commands in IM examples were written under a UNIX (Linux/mac) environment. However they can generally be used with some changes in a Widnows Batch Script environment. See http://imagemagick.org/Usage/api/#windows for a guide and other window specific notes that have been sent to me. (I am not a windows user) Now. It seems to me that the IM command "stream" should be either converted into a new command called "tile_extract" or something like that, as well as a reversed method, that will use pipelined image processing techniques to convert images to and from a set of tiles that "convert" can then handle better. "stream" can extract a single 'crop' region from a larger image in this pipelined way. But only one area at a time, when it should be able to generate all the tiles (with or without overlaps) from a ultra-large image, in one run. It could limit its output to files, and would only need to have one row of tile images open at any one time. I have also not heard of the reverse of the "stream" crop. That is re-forming a ultra-large image, using either tiles, or overlaying a smaller crop region on an existing ultra-large image. Can othe IM users report to me how thay are doing this type of operations, forward or the reverse, so that I can include it in IM examples. Non-Im methods also accepted in this case, though usally only with a link to some other site documenting that method.
