- PICTcompare
- ____________________________________________________________
-
- Using this program, you can compare PICT files, and find out if they
- are identical, or at least very similar. The program works on all PICT
- files, including Quicktime compressed pictures.
- PICTcompare also identifies two pictures when
- - one of them is grayscale
- - they don't have the same size / aspect ratio
- - they have a different intensity
- - they have a different pixel-depth
- - and when one of them is blurred
- PICTcompare works best on digitized images, like scanned photos.
-
-
- Using PICTcompare
- ____________________________________________________________
-
- The simplest operation is to use the 'Search Folder' command on any folder
- containing PICT files. Then PICTcompare loads all needed information and
- compares all pictures with each other. If the pictures are compressed,
- this may take a while. The name of the current picture processed is
- displayed at the bottom of the main dialog. When PICTcompare has finished
- it's task, it displays a list of similar pictures, sorted by the "compare value",
- which means the most similar pictures are at the top of the list. This
- compare value is also displayed within the main dialog.
- See the reference section for more information about the other commands
- and the vect resources.
-
- Limitations:
- - Only 1000 pictures may be compared with each other.
- - Only 200 found pictures will be display.

- File Menu
- - Load Master
- Load a master image for the following compare operations.
- - Compare with Folder
- Compares all images within this folder (and all subfolders) with the
- master image set using the 'Load Master' menu command.
- - Search Folder
- Compares all images within this folder with each other. (Doesn't
- use the master image)
- - Preferences
- Limit value :
- This sets the limit for a compare operation. The lower the
- value, the more the same they have to be. Absolut identical pictures
- have values between 0 and 10, picture that are most likely the same
- have values between 11 and 20. Sometimes there are similar pictures
- with values over 20, therefore a good limit value is between 25 and 30.
- Add vector resource :
- When checked, the compare information (202 bytes!) of each picture is added
- within the picture as a 'vect' resource (id 128). The next time PICTcompare
- needs to compare this picture, it just loads this resource and does not
- have to load the whole image. If the pictures are compressed, this
- makes it a LOT faster.
- - Remove Vect Resources
- Removes the vect resources from all pictures found within this folder.
- (and subfolder)

-
- I made PICTcompare, because my archive of pictures got much to big!
- I couldn't tell which picture I already had, and which not. Therefore I thought,
- let the computer do the work, and compare all pictures for me.
- I did various of tests and PICTcompare always found the pictures that
- were more or less the same.
