Issue with converted TIFF files

Aspose.PDF Product Family
1

Hi,

I am using apose-pdf-9.7.1 jar to convert pdf files to TIFF format.

I have attached a sample file which has 5 pages (original and converted TIFF).

If i open the converted file in “IrfanView”, it shows as if there are 6 pages and last page is blank.

The users say 4 byte offset is not 00 00. Instead it has a different number, which makes the number of pages incorrect.

Please see the description below grabbed from https://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf

An Image File Directory (IFD) consists of a 2-byte count of the number of directory
entries (i.e., the number of fields), followed by a sequence of 12-byte field
entries, followed by a 4-byte offset of the next IFD (or 0 if none). (Do not forget to
write the 4 bytes of 0 after the last IFD.)

Please take a look. This is very important
