2000.04.12 09:23 "JPEG tiled TIFF files", by Paul Preuveneers
Anybody have an idea of methods to compress and store JPEG tiles within a TIFF file. I am using the IJG groups libjpeg distribution to compress the data but there are no real resources for methods to create the new TIFF file (that I can find). If there is any out there I would be grateful if you could direct me towards it.. At the moment I get errors telling me that there is an unknown data compression algorithm 7, which the doc says is JPEG. Is it that the program used to read the image is old and doesn't understand what tags are set? Basically what I need to know is: What tags do I need to set/use. Such as JPEGTables/compression and what do I need to set them to? Do I need an abbreviated compression format or will the interchange Jpeg format be ok? Thanks Paul Preuveneers
