Hi, we are having a problem converting PDF documents to TIFF using JPEG compression using the "asp_PDFToImageConverter2" method. The resulting TIFF files are very large, and are not compressed. I am attaching the sample batch with input PDF documents and the output TIFF files. I am also attaching the current set of VeryPDF dlls that we have. Following are our parameters to the using the "asp_PDFToImageConverter2" method:
X Resolution: 200
Y Resolution: 200
Bitcount: 24
Grayscale: False
Compression: 7
Quality: 100
This issue is critical to us as it may turn into a show stopper for one of our existing customers. Please let me know if you need more information.
===================================
Thanks for your message, just for checking, please use COMPRESSION_PACKBITS to instead of COMPRESSION_JPEG (7) to try again, will you get smaller TIFF file with COMPRESSION_PACKBITS compression option?

===================================
Our customer requires JPEG compression. How can we get the JPEG compression working? Thank you.
====================
Thanks for your message, please delete p2isdk.dll file from “Current VeryPDF Dlls” folder, then you can convert your PDF file to JPEG compressed TIFF file properly.

What is the purpose of p2isdk.dll? What does this DLL do? We can completely remove it without affecting other parts of the conversion process? Thank you.
====================
I tried removing the DLL and re-running the conversion. The resulting TIFF images cannot be opened in Windows Image/Picture Viewer or MSPAINT. These programs say that the compression of these images is not supported. I can only open the images in FSViewer. Is there any else that I need to do in order to get these programs to open the resulting TIFFS?

====================
Yes, this is normal, because MSPAINT can't view the JPEG compressed TIFF files, if you wish view the color TIFF files in MSPAINT, you need compress the TIFF files with Packbit compression technology. JPEG compressed TIFF format is not supported by most image viewer applications.
p2isdk.dll is another method to render the PDF files, yes, you can remove it without affecting other parts of the conversion process.
