Compression
In order to view or edit page-level content like streams of graphics operators, it is nec-
essary first to remove the compression used for the data stream. This can be achieved
with the
pdftk
uncompress
modifier:
pdftk compressed.pdf output uncompressed.pdf uncompress
The process can be reversed (following manual editing, for example) by using
compress
instead:
pdftk uncompressed.pdf output compressed.pdf compress
