A (draft) specification of the JPEG SmartScale extension is +available as a contributed document at ITU and ISO. Revision 2 or later +of the document is required (latest document version is Revision 3). +The SmartScale extension will enable more features beside lossless resize +in future implementations, as described in the document (new compression +options). + +Add sanity check in BMP reader module to avoid cjpeg crash for empty input +image (thank to Isaev Ildar of ISP RAS, Moscow, RU for reporting this error). + +Add data source and destination managers for read from and write to +memory buffers. New API functions jpeg_mem_src and jpeg_mem_dest. +Thank to Roberto Boni from Italy for the suggestion. + + Version 7 27-Jun-2009 ---------------------- |
