Hi-- thanks for your support of my ancient bug. Now that there are two
of us who want this, maybe we can petition for it as a wishlist item, at
least.

I completely understand why they closed it -- what you and I are doing
with imagemagick is to use a "worse" or "lossier" compression scheme to
compress the file to be smaller than xsane can possibly make using any
of its options. The person closing the bug saw that it produced
artifacts in the resulting image, which is to be expected.

Since I almost exclusively scan black and white documents, I have been
satisfied with my technique for scanning the document as black and white
300dpi multi-page .ps files, then using ps2pdf to convert the single
multi-page file to pdf. This produces an acceptably small pdf with
extremely acceptable quality for my particular circumstance.

IF, however, you are scanning color documents, you probably want much
more control over the settings. As the person who closed the bug
implied, compression artifacts might be unacceptable for some
circumstances. Also if your documents use solid color, such as blue or
red ink on black and white forms, scanning to a format with a limited
palette BEFORE compressing would create a small file and eliminate the
compression artifacts. SO it's not necessarily a simple issue.

I was hoping for some more options, maybe a way for xsane to call the
imagemagick convert command during the save process so it would be
possible to add some additional tweaking, while still preserving the
ease of use xsane offers.

It would be REALLY nice to configure and save more options for scanning,
such as compression algorithm and level, pdf display name, and maybe the
PDF page size size and resolution, if it needs separate control.

NOTE: xsane can save multi-page .ps files, and in Gnome, and you can add
ps2pdf as a right-click command in Nautilus (the GNOME file viewer) by
right click --> Open With --> Custom command... . SO I have not missed
this requested feature, EXCEPT when I am dealing with a file that
doesn't work with the defaults in ps2pdf. (For example, a legal or
Tabloid size document would get truncated by ps2pdf unless I pass some
more arguments. For those situations I usually just scan each image to a
file, open and place the images in an OpenOffice document, and save the
pdf from there.)
