Hi Justin,
Thank you for your reply.
Yes, I quite okay with generic index file because I often to use for loading PDF and other types to CMOD.
The generic index file that I have ever used as below format. (Offset=0, Length=0)
...
GROUP_OFFSET:0
GROUP_LENGTH:0
GROUP_FILENAME:File1.pdf
...
GROUP_OFFSET:0
GROUP_LENGTH:0
GROUP_FILENAME:File2
...
But I mentioned about PDF merge files that got from arsdoc_get, they're not append file2, file3, ... to page 2, page 3, ...
But it append/build something like a layers or binary combined.
Indexer has reference to same file but changed on offset and length
...
GROUP_OFFSET:0
GROUP_LENGTH:102187
GROUP_FILENAME:PDF-TIV2.pdf.0.PDF-TIV2.PDF-TIV2.out
...
GROUP_OFFSET:102187
GROUP_LENGTH:681891
GROUP_FILENAME:PDF-TIV2.pdf.0.PDF-TIV2.PDF-TIV2.out
...
Do you know or can share document that explain about this PDF's specification or utllity to split it back to original?
