single-tiled images * Only works for single-tiled images --> will error out cleanly, as currently in other cases * Save re-reading the codestream for the tile, and re-use code-blocks of the previous decoding pass. * Future improvements might involve improving opj_decompress, and the image writing logic, to use this strategy.

2017-09-01Various changes to allow tile buffers of more than 4giga pixelsEven Rouault
Untested though, since that means a tile buffer of at least 16 GB. So there might be places where uint32 overflow on multiplication still occur...
2017-09-01TCD: allow tile buffer to be greater than 4GB on 64 bit hosts (but number of ↵Even Rouault
pixels must remain under 4 billion)
