The version 1.4 has been released (the official release).

Added the concept "User-defined list of unlike images in the gallery". If the program marks some pair (or group) of images as similar ones and displays them in the list of duplicates (as they satisfy to the given criterion of similarity), but yours personal visual perception of this pair/group says to you that this is not the case and the images have nothing in common with each other, you can forcedly mark them as UNLIKE images. It also can be made if you do not want to delete any from the duplicates (for whatever reasons). The program will not display the marked images in the list of the duplicates at the following procedures of search. If a certain third image similar to one of presented in the list of unlike images would be found, the program will display only one image from the group of unlike ones in the pane of duplicates, having marked it by a green arrow (clicking on this arrow allows to thumb through the group). The operations with such "pseudo-groups" are limited!
Addition of new pairs in the list of unlike images is accomplished directly from the window for comparison of two images (the button with sign of unequality between names of the images). It is possible to look through and to edit the list of "not duplicates" as well as the list of duplicates. The used operations for the list of unlike images are limited to comparison, viewing, and removal from the list. The appropriate menu items ("View" of the main menu) and tool buttons (three buttons with glasses) have been added for switching between various modes of viewing:
1. Files of the gallery,
2. List of found duplicates,
3. User-defined list of unlike images.

Added the options to store the result of last search of the duplicates and the user list of "not duplicates" in gallery files. The gallery file format has been slightly changed correspondingly, and the old versions of ImageDupeless (up to 1.3 inclusive) cannot read gallery files created by the new ones (1.4BETA and higher). The given options are called "Store list of duplicates in gallery files" and "Store user list of unlike images in gallery files".

Added the very useful option to compare images from two already generated galleries (see the menu item "Tools/Compare with new images", then select "another gallery file (*.glr)"). At that there is no repeated reading of the images. The given option works only in the registered version.

Added the possibility to change size of the window for comparison of two images and to maximize it.

Added the buttons for renaming/moving image files in the window for comparison of two images (the buttons with the inscription "Abc" located near the buttons for removal of images). It is possible to select a new file name and path in the special dialog for renaming/moving image files. At that, there is a possibility to set quickly names and directories of the current files in the window for comparison and the given settings will be stored for the following sessions. There is a possibility to add easily an index to the file name (if a file with such name is already exists and you do not want to replace it). Thumbnails for source (renamed) and target (if exists) files are optionally displayed in the dialog. Besides, if these files are binary equal, sign of equality will be displayed between the thumbnails.

Added the buttons to mark the images displayed in the window for comparison of two images for following deletion (small rectangles under the deletion buttons). The marks will be updated in the left pane of the main window (red ticks in the top left corner of thumbnails) after the window for comparison has been closed. Please, select the menu item "Delete selected images" to delete the marked images.

Changed appearance and location of the element displaying quality of compared images in the window for comparison of two images. There are three parameters of quality:
1. Area of the image,
2. Size of its file,
3. Relation of the file size to the image area.
The vertical blue bar is located between the buttons for removal of images. If compared parameters are equal, the sign '=' will be drawn on the bar on the place appropriate to the parameter. If some image has better value of a parameter, the sign '+' will be drawn near the bar on the side appropriate to the image. At that, distance between the sign and the bar ... If the image files are binary equal, the big red sign '=' is displayed instead of this element. The numerical value of a level of difference for compared images is located now under the given element.

Appearance of the bottom part of the window for comparison of two images:

Added some hot keys to raise efficiency of work in the window for comparison of two images:
"R/V" - passes to the previous/next pair of images;
"F" - adds the current pair of images into the user-defined list of unlike ones;
"D/G" - deletes left/right image;
"C/B" - marks left/right image for following deletion.

Added the progress bar of removal and the cancel button to interrupt the process (but not to restore already deleted files, so do not forget to set the option "Put deleted files in Recycle Bin") in the dialog for removal of marked images.

In the dialog with the list of the files marked for removal double clicking the left mouse button on a file name now starts a program for detailed viewing the appropriate image (as well as in all the other lists).

Added displaying the warning that it is desirable to turn off the option "Store thumbnails in gallery files" for saving of time and memory when size of the gallery is more than 30000 images (generally, we do not recommend to create galleries of the huge sizes, it is much better and more efficient to divide the huge gallery into themes by their root directories and to operate with the separate galleries).

Added "*.JPE" to the list of supported file extensions.

Changed approach to shareware limitations and warnings. The program is provided now by a trial period. The other limitations has also been changed, in particular:
Working with the first pair of thumbnails in EACH row is possible now in the duplicate pane;
Some limitations in the window for comparison of two images have been relaxed;
Shareware warnings have been added;
It is not possible to store the lists of found duplicates and unlike images in gallery files;
30-day trial period has been added.

Corrected the old dialog for moving images (now it is possible to change only file names).

Fixed bug where the confirmation for removal of files was asked always in the window for comparison of two images, not depending on program settings.

Fixed the other petty defects and bugs.

10 Jun 2002:

The version 1.3 has been released (the official release).

Added the mode of displaying thumbnails of all the gallery images in the left pane of the main window. The tool button and the corresponding menu item allow to switch between the modes of displaying duplicates and the whole gallery.

Added the option "Store thumbnails in gallery files". If you wish to use a gallery in off-line mode, you must set this option before creation of the gallery! Namely presence of thumbnails in gallery files allows to look through the galleries even if the source image files are absent on a disk. However turning this option off forces process of gallery creation 2-2.5 times faster and makes size of the gallery file 3 times smaller. This option has no influence on quality of further search of duplicates. We greatly recommend to turn this option off when working with huge image archives on HDD (more than 2Gb) and/or under deficiency of RAM. Possibility to add thumbnails into the galleries created under such condition will be appeared in the near future. Small benchmark for this mode can be found at the page "About the program".

Removed the limitation!: in the unregistered version different images (rather than the same ones) are displayed now in the window for comparison of two images.

Added the option "Put deleted files in Recycle Bin" (the "READ-ONLY" attribute is ignored now during deletion). The option "Ignore the READ-ONLY attribute" (if it is set, the files marked as "READ-ONLY" will be deleted without the additional warning) is temporarily grayed.

Added several visual elements allowing to predetermine quickly a ratio of quality for compared images in the window for comparison of two images. A level of difference for shown images is displayed numerically by color text (the used palette consisting of blue color gradations is similar to the palette used in the left pane of the main window) below the window (between the buttons for deletion of the images). If the image files are binary equal, the red symbol '=' is displayed instead of the number. Besides three symbols corresponding to the following parameters of images: a) the area of the image, b) size of its file, c) relation of the file size to the image area, are located abreast under the buttons for deletion of the images. The symbol '+' is located under the image that has larger value of the appropriate parameter, correspondingly, the symbol '-' is located under the image that has smaller value of the parameter, and the symbol '=' is used if the appropriate values coincide.

Added the possibility to start a program for detailed viewing the image in the window for comparison of two images by double clicking the left mouse button (double clicking is also works for thumbnails of neighbors in the registered version).

Slightly accelerated the process of loading of new image pairs in the window for comparison of two images (remark: the time of loading of the images is increased almost three times when the mode of displaying neighbors is turned on; it is recommended to use the given mode if only it is really necessary for you or if your computer is powerful).

Removed blinking and added image caching to accelerate work in the window for comparison of two images; added the tooltips containing the complete file names over thumbnails of neighbors.

Added the option "To use internal viewer for thumbnails" for viewing images by double clicking on thumbnails.

Added displaying the number of the current group of duplicates and the general number of the groups (in brackets) in the title of the window for comparison of two images.

Corrected output formats for date of last modification of a file and for its size in the window for comparison of two images and in the right pane of the main window.

In the left pane of the main window the rows of duplicates are sorted now in descending order of an average level of similarity of the images in the row (works only in the registered version).

Added the possibility to start a program for viewing the current image in the left pane by pressing the key button "SPACE".

Added restoring width of columns of the list in the right pane at the next session.

Icons in message boxes has been brought to conformity with types of the concrete messages (question, information, warning).

Slightly corrected scrolling when the current image has been pointed out.

Accelerated deletion of images from the gallery.

Accelerated displaying the list in the right pane at a plenty of the gallery images.

Fixed bug where the left pane of the main window was not always repainted after the window for comparison of two images has been closed.

Fixed bug where the dirty wasn't set after changing a root directory for the gallery.

Fixed bug where not always neighbor (in alphabetical order) images were shown in the window for comparison of two images.

Fixed bug where a thumbnail was not always shown in the window for comparison of two images during the off-line mode.

Fixed the other petty defects and bugs.

Fixed bug where the left window was not updated automatically, if the process of reading or comparison was interrupted or did not give results.

The options in the dialog for comparison of two images are kept now in the system registry and can be restored at the following session.

Sped up the refresh function for huge galleries. Warning for the evaluation version: all the gallery will be scanned, but no more than 1000 images will be included into it.

Found (but not corrected) bug where fallout of the scroller in the left pane is possible at a plenty of duplicates under Windows 9x/Me (the problem is not shown under Windows 2000).

Added one more limitation to the evaluation version: the dialog for comparison displays the same image.

Added possibility to mark forcedly all the gallery files as off-line at absence of only some of them on the data medium when the gallery are read or refreshed. It accelerates work when the gallery are stored on CD.

04 Mar. 2002:


Unlocked the parameter "Maximal level of difference", but I do not advise to depart especially from the value 11. This parameter is also kept from one session to another.

Added the dialog for comparison of two images. It is made active at double click on rectangle to the left of image groups in the list of duplicates. By default first two images in a row will be compared. To compare other pairs in the row it is necessary to select equally two images by single click (selected images are highlighted by a black background).

Fixed bug at removal of an image through the list of duplicates when a row contains more than two thumbnails.

A number of parameters are kept now separately from a gallery file (in the system registry) and accordingly are restored at the following session.

Added the menu item/toolbar button "Delete the selected images" (works for the selected thumbnails (highlighted by a black background) in the left pane).

Added output of the warning that the image is absent on the disk at double clicking (for off-line mode). For such images all the known information and the corresponding thumbnails are also shown.

Added output of names of the files (after the gallery has been composed) located at the given path but not included into the gallery, because the program has not taken up them as the images.

Added output of the offer to save the gallery at exit. (Tracking changes of gallery contents at various operations is not made).
