| tiff_memory_mapping.diff | implement support for file memory mapping for tiff reading libtiff will by default attempt to establish a memory map for reading a tiff file. Implement the callbacks to establish this in Qt's tiff handler, since this will save data copying, particularly in the case where the input file is already in memory as a resource or QBuffer. . Also, this makes sure that QTiffHandler utilizes libtiff's default, and hence best tested, code path for tiff decoding. Specifically, it avoids a hitting a bug that breaks reading of certain tiffs in the newly released libtiff version 4.5.0. |
