Hi all, I am using openlayers to navigate large tiled microscopy images in "progressive jpeg" format. I'm using the TMS layer and my own getURL function to retrieve tiles.
Progressive jpegs are the kind that first load a blocky/blurry low resolution version of the image and then get progressively more detailed. When I have a tiled image with smooth backgrounds and/or very little image detail within the tiles (i.e. the jpegs are highly compressed, the file sizes are pretty small), they load just fine. But when I try a tiled image with lots of small details (i.e. less compression, bigger jpeg filesizes), they seem to be "stuck" either partially loaded (strips of white empty space) or they are only loaded at low resolution (blocky/blurry first pass of the progressive jpeg). My question is, is there a way to force that the tile should be loaded completely to its highest resolution (i.e. don't bother showing intermediate resolutions, just wait until you have the full res jpeg). Is this a timeout issue with tile loading? Is there some way I can instruct OpenLayers to spend more time loading each tile so that it arrives complete? Thanks, -sg _______________________________________________ Users mailing list [email protected] http://openlayers.org/mailman/listinfo/users
