Hello Focal Point, we have problems with JPEG Files from a DB in a PDF Report. The Files in the DB are compressed in a BLOB Field. They are shown correctly in the PDF Report but the size of the PDF File shows the size of the uncompressed JPEG File. We would actually expect from WebFOCUS that it includes the original, compressed JPEG format into the PDF but as mentioned, it seems to uncompress it before including. How can we achieve a still compressed JPEG image included into a PDF file by WebFOCUS Example: File compressed: about 1 MB Resulting PDF: about 6 MB (the raw bitmap size: 1700 * 1200 px * 24Bits -> 6 MB) Thank you and best Regards, Klaus Molt WebFOCUS 7.7.03 | ||

Have you tried the FILECOMPRESS command?
Meanwhile, I don't know anything about blobs, but I'm pretty sure that a blob has to be decompressed for any program to open it. I'm certain that even Adobe PhotoShop cannot open a compressed blob file. Francis  Give me code, or give me retirement.

Thank you for your Answer. Unfortunately the FILECOMPRESS does not affect the JPEG files in a PDF as WF sais: "Note also that using SET FILECOMPRESS=ON will not reduce the size of images in a PDF file, since images are already saved in compressed form." also the PDF doesn't even show any content. But as already mentioned, for us it looks like the files get enlarged to raw bitmap size instead of being compressed. I don't think the JPEG file has to be uncompressed, if i directly download the JPEG file from the BLOB field in the DB even the windows photo viewer can show it. Thanks and Regards WebFOCUS 7.7.03 | |||

What is the size of the image file? Is the image shown more than once in the PDF? Could that be a factor in the size of the PDF file? Francis Give me code, or give me retirement.

I have some new Informations: There are different Filter Attributes for Pictures in PDF Files: - Filter Attribute /DCTDecode for JPEG Files - Filter Attribute /FlateDecode for PNG Files In WebFocus the FlateDecode seems to be used as standard. "<< /Type /XObject /Subtype /Image /Name /Im1 /Width 1600 /Height 1132 /BitsPerComponent 8 /ColorSpace /DeviceRGB /Filter Ý/ASCII85Decode /FlateDecode¨ /Length 2306227 >> stream" A JPEG File included into PDF has usualy a string like: "<>stream" I hope this may help. Thank you in advance. Best Regards. WebFOCUS 7.7.03 | |||
