------- Additional comments from [EMAIL PROTECTED] Tue Jul 11 06:54:55 -0700 2006 ------- Currently the PNGs produced by OOo only contain one IDAT chunk. This chunk can easlily get absurdly large e.g. for high resolution scans. Reading and checksumming this huge chunk is very costly from all perspectives: IO, CPU, cachability and memory consumption. This is especially bad when considering that this high cost is nowadays often wasted, because only a small part of the chunk data is needed (see issue 55174). I suggest to limit the chunk length to a cache friendly size, e.g. 256k. --------------------------------------------------------------------- Please do not reply to this automatically generated notification from Issue Tracker.
