Hello list I have a dataset visualised as a series of 180 or so individual images, currently rendered as PDFs
To be legible/ useful/ accessible, I need to display these simultaneously as a one big (gigapixel) mosaic of non-square images, tiled so as to form a seamless user-traversable (mouse-driven pan + zoom) image. For ease of navigation the tiles should also be mapped toroidally, I think. Ideally I'd just keep everything as a vector (they're graphs), but I can't find any tools thus far that will handle PDFs in this way, meaning stitching/shifting large bitmaps around. If we're forced to use bitmaps we might as well do some realtime post-processing for fisheye/ hyperbolic views, hence that's not so bad I assume pinging around big tilesets in realtime must be a mundane requirement for astronomers, GIS people etc or anyone needing to explore large images/ datasets visually, eg some of whom must use OSX, therefore I'd expect to find some work done here already So: I'm playing with Quartz Composer to do this at present, which can only handle images less than 2000px square, I believe (FSR it rasterises my PDFs before displaying them at a lower res than the original - as a newbie, I don't understand why you'd want this Similarly, I've failed even to scan + load + place a directory full of images into an X * Y grid and manipulate it as a single sprite, but I imagine that's what's needed for a start, Can you help? All tips very welcome. _______________________________________________ Do not post admin requests to the list. They will be ignored.
