12-21-2007, 5:47 anandhavelu Joined on 08-21-2007 Posts 7 Compression performance varies from leadtools 14 to leadtools 15 Hi We were using leadtools 14 raster imaging api  for compressing images to jpeg. We now have upgraded to leadtools 15. But the output file sizes have increased. A sample: Input jpeg file size 16 kb Lead14 output jpeg file size 12.2 kb Lead 15 output jpeg file size 15 kb Following function call is used in both versions for the conversion .The values of the variables are also same. bpp=24 jpegquality=52 L_FileConvert(inputFile, outputFile, FILE_JFIF, fileInfo.Width, fileInfo.Height,                         bpp, jpegQuality,NULL,NULL,NULL) How do i fix this without compromising on quality? Thanks, Anand    Report

Also, can you put the 3 JPEG files (source and 2 results) in a ZIP or RAR file and attach them to your post? Thanks, Maen Badwan LEADTOOLS Technical Support    Report

It's highly recommended to recheck the same issue using the latest LEADTOOLS 14 and 15 patches. Please send your LEADTOOLS v14 and v15 serial numbers to support@leadtools.com and ask about the latest patches. Thanks, Maen Badwan LEADTOOLS Technical Support    Report
