tiled image with image pyramid
BinuJanardhanan last edited by BinuJanardhanan
I am implementing an image viewer to render the tiled image. The image is of very large size (cannot fit into the memory fully) and have multiple resolutions (image pyramid).
I have to show large images. We figure that the image needs to be broken into tiles,
and only the needed tiles are loaded into memory. As you pan around
the image, tiles are load off disk, kind of like google maps, It not for map viewing the application.
Is there any opensource framework available?. Is there any solution in Qt?
The Graphics View Framework might be of interest as a starting point.

@BinuJanardhanan You may want to check out OpenImageIO. It'll generate MIP maps for you, and work with very large tiled EXR's using a texture cache system to access a subset of the data that fits in memory.
