@Chaudakh: I've tried the last version, the sub-folders are created correctly and it works, but I've found a little bug in file naming: if a card is present multiple times in the super-set, it gets a number appended to the filename as if all files were in the same directory.
Maybe an example is clearer:
MPS super set has sub-sets based on scryfall codes PMPS0*, inside the sub-folders, lands are named island6 instead of island as if they were all in the super-folder MPS
When the option to create the sub-folders is checked, they shouldn't be numbered this way imho (and forge thinks the same)
@ezellohar81: I understand. You obtain what you described because I did not implement anything specific to the naming of the scan file. The file has the same name as if it was stored direcly, in the "super folder" MPS.
However, I agree with you: the alternate mark could be removed... but only if there are not multiple card copies with same name in the same subset. The case of multiples copies of "Island" in the same subset must be handled sowehow. If for example Island5 and Island6 of MPS have to be renamed Island1 and Island2 in subfolder PSPS0*, it will be a mess because the alternate marks stored are 5 and 6 (according to the GEx table), not 1 and 2. As a consequence The alternate markers 1 and 2 which have been locally redefined have to be stored somehow in the table for GEx to be able to find the correct file when displaying the scan.
I am not really keen on overloading the data management/data table for this, but I will do it.
Version 7.0 is released. Note you will need to update to Microsoft .NET Framework 4.7.2. (if not already done).
The scan extraction routines have been fully recoded due to a server migration at scryfall. It is now more robust.
In addition, it is now possible to extract the quality of scans from Scryfall. The saved scans will now have exif data related to their quality in the "comment" exif zone. This would help to better manage scans between the ones with low quality and the ones with high quality, as it appears in the pictures in attachment. You need to activate the option 'show scan status' to get advantage of those new functionalities!
Moreover, a new panel has been created to get magnified views of scans or to rotate them. Just click on the magnifying lens in the toolbar, or double click on the scan. You will get the full path in the window title, and some image characteristics in the dedicated group (size, dimensions, resolution...)
Transparency of the Scryfall's pngs are now correctly managed.
Many minor bugs have been fixed as well.
Enjoy and feel free to report any bugs you may find. Stay safe.
