To edit values of parameters select the menu item "Tools/Options...".
The section "Creating/Comparison"
The parameter "Maximal level of difference", at which images
are still considered as identical ones, specifies the basic criterion
of comparison (in percentage; 0% means very similar images from the
point of view of the program). The recommended limit of values is [0-15]%.
It is established by practice, that the optimal value is 11% (the default
value). I do not recommend to depart too far from it. The program can
consider all the gallery images as similar ones as a result of setting
too large values (more than 20%). The value of the given parameter can
also be changed via the comparison dialog.
The parameter "Show images during search and comparison" specifies,
whether the images should be displayed in the appropriate dialogs (it
can be set also directly in them) at reading and comparing images.
The parameter "good image quality" controls quality of displaying
these small images. These options improve interactivity, but slow down
substantial work, this slowing-down will be significant when thumbnails are not
stored in the gallery (see the parameter "Store thumbnails in gallery files").
Don't turn them on if your computer is weak. By default the parameter "Show images"
is turned on, the parameter "good image quality" is turned off.
The parameter "Read GIF files" specifies, whether GIF images
should be read out and included into the gallery. It is turned on by
default. It is recommended to turn off it only when the program crashes
at reading GIF (it is possible as a result bugs in used free libraries
for reading images).
The parameter "Read ICO files" specifies, whether ICO images
should be read out and included into the gallery. It is turned on by
default. If the icon is multiframe the frame with the maximal size is
choosen.
The parameter "Try to accelerate and read BAD files" specifies, whether defective images
should be read out and included into the gallery. Besides, the option turns on
new rapid reading algorithm. The additional parameter
"Fast reading of the large JPEG files" accelerates reading of large
JPEG images during working with the gallery. They are turned on by default.
It is recommended to turn off these options if only you have troubles during
creation of the gallery.
If the parameter "detailed log file" is turned on the decoding
errors are additionally written in the log file, besides, if the program
crashes during image file reading, the name of the last readout file will be
shown at the following loading of the application.
The section "Viewing"
The group of parameters "Use for image viewing" specifies, what
viewer should be started at double click on a thumbnail. It is possible
to assign a concrete viewer, to establish starting the program registered
in the system for the given file type (turned on by default), or to set
the internal viewer (the latter displays thumbnails only).
The parameter "do not consider the case of names in the gallery"
turns off case sensitive sorting the names of files in the right pane of the main
window. It is turned on by default.
The group of parameters "Parameters to show the images in the groups of duplicates"
allows to restrict "noise" effect when working with the large groups of duplicates.
In such groups some pairs of images may have the difference level essentially more than
that of set for search. To avoid showing these groups (for example, in the dialog for
series merging) you should turn on the option "Avoid to show the pairs with difference
level more than the given value (%)" and set the required difference level by means
of the slider. When the oprion "is equal to the current value for search of the duplicates"
is turned on the difference level is always equal to the current value of the appropriate
parameter set for search of duplicates. By default the first option is turned on, the
second one is turned off.
The section "Viewing:Main window"
The parameter "Icon size" allows to set size of thumbnails displayed
in the left pane of the main window.
The group of parameters "Show in the thumbnail window:" controls
what particular information will be displayed on thumbnails in the left pane
of the main window. All of them are turned on by default, except for displaying
full file paths.
The section "Working"
The parameter "Ignore the READ-ONLY attribute" specifies,
whether the image files marked as read-only should be deleted straight
away or after the appropriate approval. It is turned off by default
(in order to prevent casual removal).
The parameter "Put deleted files in Recycle Bin" specifies,
whether the image files should be deleted irretrievably or moved into
Windows Recycle Bin. It is turned on by default.
The parameter "Work with descript.ion" specifies, whether the
description files "descript.ion" should be processed (when they are present
in the directories with the images). It is turned on by default.
The parameter "Check accessibility of images during gallery loading or refreshing"
specifies, whether availability of images on the data medium should be checked during
gallery loading or refreshing. It is turned off by default, which allows to speed up
processes of opening and refreshing large on-line galleries stored on HD.
If you prefer to store your image collections on CDs, we would recommend
to turn on this option.
The section "Messages"
The group of parameters "Log file" controls maintenance of the
log file of the program. Logging is turned off by default. At detection
of a bug in ImageDupeless it is recommended to turn on maintenance of
the detailed log file and to send it together with the bug description
to the author.
The parameter "Require approval at removal of a file" specifies,
whether a warning should be displayed at removal of images from the
gallery. It is turned on by default (in order to prevent casual removal).
The parameter "Show tips of the day" specifies, whether tips of
the day should be displayed at start of the program. It is turned on by default.
The tips could be helpful for novice users familiarizing with the program.
The parameter "Display statistics at the end of the session" specifies,
whether statistics should be displayed at the end of the session: working time,
the number of images (read, processed, found duplicates, marked as unlike, deleted,
moved, replaced, marked automatically by the program). The statistics is displayed
on the screen and printed into the log file if the logging option is turned on.
The parameter is turned off by default.
The parameter "Generate the list of problematic images" specifies,
whether the list of images for that disturbances in structure of their files were
detected during their reading should be displayed. The problematic images can be kept
in the gallery, can be excluded from it or can be moved into an individual directory.
The program can work with such images, but to raise stability it is recommended
to move them into an individual directory outside of the gallery and to resave
them by means of any graphic editor. The parameter is turned on by default.
The section "Storing"
The parameters "Store list of duplicates in gallery files"
and "Store user list of unlike images in gallery files"
specify, whether result of the last search of duplicates and the user-defined
list of unlike images correspondingly should be stored in gallery files.
This is possible only in the registered version of the program. They
are turned on by default.
WARNING: the lists of duplicates and unlike images will not be stored
if you select comparison with new images or with another gallery.
The parameter "Store thumbnails in gallery files"
specifies, whether thumbnails for images should be stored in gallery
files. It is turned on by default. If you wish to use a gallery in off-line
mode, you must turn on this parameter before creation of the
gallery, which allows to look through the galleries even if the source
image files are absent on a disk. However when this parameter is turned
off process of gallery creation is performed 2-2.5 times faster, and
size of the gallery file and expences of RAM in process of its creation
(before first saving) are reduced as much as
3 times (approximately 7Kb per image when thumbnails are stored in
the gallery file and 2.5Kb per image otherwise), but you will pay
for this by absence of thumbnails in the left
pane at inaccessibility of image files or by low speed of displaying
thumbnails of the duplicates or the images of the gallery at their presence.
This option has no influence on quality of search of duplicates. If
you prefer to store your image collections on compact discs, you should
turn on this parameter. If you prefer to put the images on a hard disk,
and the number of images is greater than 40000,
we would recommend to turn off the given parameter at work.
The section "Series of images"
The parameter "show series indicator in comparison dialog" specifies,
whether search of the image series should be accomplished and the icon "series indicator"
should be displayed under the images in the comparison dialog when the image series
corresponding to them are found. It is turned off by default. This parameter duplicates
the option of the same name in the dialog for comparison of two images.
The parameter "generate the list of files according to the current state of the directory"
specifies, how the list of files for procedure of finding the image series should be generated.
When the option is turned on the source list of files for finding the series is generated
according to the current state of the directory with the images, otherwise the list
is generated according to the current state of the gallery file. In the latter case
generation of the list is accomplished faster, but may lead to non-adequate results
if the gallery has not been refreshed for a long time (new images may be appear,
a part of images may be removed). The parameter is turned off by default.
