PAUL - yet another image viewer
For some special purposes I wrote a kind of an image viewer named
paul = Program zur Auswertung und
Umwandlung von Laserbildern
(for non German speakers: Program to evaluate and convert laser images).
The background is that I take some pictures of crystals using a
high-speed film-camera which works with laser light.
The intention is to get a "digital" film. Using a slide-scanner
(Nikon LS-20) I scan the images by a program derived from SANE's
xscanimage (I changed xscanimage to get PNG-images with special
chunks I want to use in paul).
Some special features I needed for my hobby of photography were
added which make paul interesting for common usage. Especially
HTML editors will find a useful tool when trying to build
click-able maps of images.
So what is Paul:
- Yet another image viewer.
- Special designed for sequences of images.
Works best with gray-scaled images, but can handle any 24-Bit
images, off course
(Remark: Gray scaled images are displayed green! It has
technical reasons to use the other colors internally. Don't
be afraid that your output will be green. It's normal monochrome
- GTK user-interface (almost all features are available from command
line and there are some which are not implemented into the
GUI yet, but it is work in progress)
- several transformations can be done quiet in background
(may be any console), as `convert` from ImageMagick does
- Because of using Imlib it is fast and can handle any image
May be it's possible to do all the image processing stuff of
paul with GIMP. But the special features are easier available
and designed for only this special purpose (may be I write
some parts of paul as plug-in for gimp).
The function to cut parts of an image is better, i.e. more minute than
this one of the gimp, because it is possible to position the
cutting box via entering pixel coordinates ... yet another
philosophy of cutting an image (which I had not seen in any
other image processing software).
- The feature to insert thumbnails into an image and output
a HTML file which uses the image as click-able map and installs
a link to a user supplied URL under the thumbnail is very
easy to use and I have not seen such a beast anywhere else.
Hopefully it will be a useful tool for HTML editors. This tool
is hidden in the menu "This Image/Insert" and requires to
select an operating widget. For a detailed explanation please
read the file clickable-map.howto
- May be you can view your images using XV, but paul is free.
Paul is released under GPL. I don't want to
compete with any other image viewer like xv or display, but
I don't use them since several month.
- Yet another user-interface:
Paul works with the following menu structure:
- (what would you expect under this item :))
- This Image:
- Operation to single image
- Marked Images:
- Operation on all marked images
- All Images:
- Operation on all loaded images
- Set global parameters for the tree operation types
There is only a `not yet finished` documentation in German
I'm sure that there will be no English documentation, because this
program was designed for German native speakers at my working
group and parts of this documentation will go into my theses.
If there will be a greater resonance I could think about English
documentation but not before October next year.
Why did I put paul into Debian?
- May be there is need for such a thing?
- I want to do more than only package other peoples software.
- May be someone can use some ideas of paul?
- May be that more people can detect more bugs and I can make paul
Paul was successfully compiled under
Linux (Debian GNU/Linux) and
Unix (I've heard rumors about some other things simulating
operating systems starting with the letter `W'. The libraries
mentioned seem to compile under those things in the development
versions. So future versions of paul could run there, but I
will not support it. If there is interest I would include
user-supplied patches of course.)
- Gtk+ version 1.2
- GdkImlib greater
or equal version 1.9.2 and the necessary graphics libraries for
GdkImlib which are libpng, libtif, libgif or libungif, libjpeg
For those who don't want to install this (very good!) library
there are #defines which disable the FFT stuff if configure
cant find the library.
- Gtk Databox
from Roland Bock. The source as well as Debian Packages
are available here.
- Gtk Imreg -- small library to
deal with image regions written by me. It was split from paul
to give GTK programmers a chance to use the image cut feature
and image inserting feature from paul.
