gscan2pdf covers the majority of my scan→file workflow, but I still
generally need to postprocess the generated PDF files, be it the
addition of watermarks, my preference for using the shell to put the
file into the target directory, the need to assign tags to the file,
or just attaching the scanned document to an email.
Right now, I save the file to a temporary path, which means I need
to face the save-as dialog, ensure I am in a temporary directory,
and hit save, and then invoke the postprocessing tool, or find the
file on disk. Which is quite a lot of extra work that I don't really
want to do.
gscan2pdf already allows me to invoke my email programme from the
File menu. In the Preferences dialog, I can also specify
user-defined tools to be invoked, either on the PNG files
(accessible by menu), or on the PDF with the save-hook.
Would it be possible to generalise the "Email a PDF" functionality,
such that I could provide a different command to be run, or ideally
provide an additional menu item for each additional command I need
to be able to access?
