NAME
paul - yet another image viewer
SYNOPSIS
paul [options] [image files]
DESCRIPTION
paul = _P_rogram zur _A_uswertung und _U_mwandlung von _L_aserbildern
(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.
PAUL IS ALPHA SOFTWARE! You should expect errors.
Short description
Yet another image viewer.
Longer description
Special designed for sequences of monochrome 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 be afraid that your output will
GTK user interface
The user interface work in progress, some features of paul are only
available via command line (See section OPTIONS).
All loaded image files are presented in an file list window.
Pressing the left mouse button on a file name selects this file and
displays it in a showing window.
Toggle marking flag by pressing the right mouse button.
To mark all loaded files press the middle mouse button.
There is a new concept called "operating image". An image can be
selected as operating image, by holding the <Ctrl>-key while pressing
the middle or right button on a filename. The filename is displayed
in the "operating image" region of the file-list and the image is
displayed in a separate window. Pressing the left mouse button on the
operating image brings it back to the file list. This enables
resorting of files and is subject of further development.
If there are more than one images selected, the Animate button is
enabled. If these images are different in size, you have to adjust
the Animation time parameter in the parameter menu to a value greater
than 0.4s.

Things which may be of special interest
Moving images
If there are more than one image loaded they can be moved to
match each other. The display method can be adjusted in the
parameter menu.
Keys in the display window while Arrow-Keys, accelerated by
<Shift>, <Ctrl> and <Caps-Lock>
0 goes back to the unmoved images
To end the moving press the Accept all moved images in the file
selection window. The images will be cut to have the same size.
Cutting images
This can be found in the This image section of the menu. Try the
behavior of all mouse buttons and the controls. May be you like
precise cutting.
Deleting borders
Try this in any operating section of the menu.
OPTIONS
-a<[*c][+b]>
enh_A_nce contrast (*c) and brightness (+b)
-b[file]
write _B_rightnesses of all images into text-file.
-c<wxh+x+y>
_C_ut image of width w and height h at pixel (x,y) or
-c<a,b_c,d>
_C_ut area in-between (a,b) and (c,d)
-d[e]
_D_ifference image (suppress "noise" up to e).
If e>0 then all equal pixels are marked white which is useful for
printing.
-e[ai]<a*b>
search for _E_xtrema of brightness of size a*b
-ea = only m_A_xima; -ei = only m_I_nima
-f[hvmM][i]
median _F_ilter of order i (default: horizontal order 3)
-g<a>[e]
make color images _G_ray
-h store _H_istogram in text-file

-i[a]
print _I_nformation about images (if a is given print Gamma curve
too)
-j[H]<a+b_file>[:URL]
insert file at (a,b). If H is given create a HTML file or append
to HTML file if it exists to display a map with click-able icons.
The link to insert will point to the optional argument URL or a
default link obtained from the name of file
This might be an interesting feature for HTML editors and has
nothing to do with the general functionality of paul. I just
needed this feature and hope that some others will use it
successfully.
Note that there is an easy to use possibility in the GTK+ menu
system under "File/Insert" which inserts the operating image
(previously selected via <Ctrl>-<middle or right Mouse-button>)
in the active image!
-m[cdf]
_M_ove images according to the first in image list.
There are three types: _Color, _D_ifference and _F_lash. paul
tries to find good matching images automatically at first.
-n _N_egativ of image
-o[PNG/TIFF]
_O_utput of processed images in PNG or TIFF format (default PNG)
-p[hv]
mirror _h_orizontal or _v_ertikal
-q _Q_uiet: no graphic display (useful for batch jobs)
-r[n][+s][-e]
Delete (black) bo_R_der / selection of real image information; n
means delete only left and right but not top and bottom border
default: threshold for "black" [s] = 20
allowed error for one pixel [e] = 50
-s delete (white) _S_canner border
-t<d>
ro_T_ate d degrees clockwise (d = 90, 180, 270)
-w[s]
animate images with s seconds delay (default s=0).
-z[i]

shrink i levels (1 level means = half the width and half the
height)
-F calculate fast Fourier transform of image
-H print _H_elp screen
CAVEATS
To say it once more: paul is alpha software. Do not expect any
marvels. Be happy if it is useful.
BUGS
Please report any bugs, comments or enhancements to
<tille@physik.uni-halle.de>.
RESTRICTIONS
Can not handle transparent images correctly and will possibly never do
because it isn not intended to do that kind of stuff.

HISTORY
Paul was developed at first to work at the command line. That is the
reason why some options are not available in the menus. If this work
is done the versioning scheme changes to 0.x.
