Description Sergio 2022-06-02 21:19:26 UTC
SUMMARY

Skanlite offers the possibility to name files automatically, including an index as in scan_####.png where #### is a number.
With the first save, it is possible to select the initial value.

This is good, but IMHO it could be improved.

Scenario: you have a non-duplex scanner and you want to scan multipage documents printed on both sides of the paper.

Suppose you have 4 pages printed on both sides. You would like to set the initial index to something (say 0101) for the first scan, with a +2 increment, to scan all the odd pages, then you would like to turn the pages, re-feed then in the ADF, set the initial index to the correct value (0108) and the increment to -2, so that you can now scan the even pages and have the resulting files nicely ordered.

The venerable `xsane` lets you do this, so skanlite should be no less ;-) What do you think?

Would like to advocate again for this enhancement.  Yes, it is true that skanpage lets you reorder the pages before saving. Still manually reordering the pages when they can be 20 or more is cumbersome.

There is also another usage scenario:

You have pages that tend to stick together, so every now and then the scanner ADF pulls in two pages at once and you miss a page. If you realize that after you have saved the pages, you need scan the missing pages and then to manually rename all the files to have them in order. But had you picked 10 as the index increment, you would be able to rename just the missing pages to have the files in the correct order. Again, yes, skanpage lets you reorder the pages, but working with the indexes is faster if you have a lot of pages.

ADDITIONAL INFORMATION

As an alternative to being able to configure the indexes on save, even better would be to be able to configure the page numbers while scanning. In this way the thumbnails would immediately get in order. Eg., on the side of the scan button I can enter the first page and the page increment. I need to scan duplex and I have a simplex scanner. I set the start page to 1 and the increment to 2 and then I press scan the odd sides. Then I set the start page to the last even page and the increment to -2 and I scan the even pages, in the thumbnails the pages end up in the correct order.
