I use a workflow like this: for every multi-song multi-page fakebook I prepare a CSV file.
Each of my CSV files contains an entry ~NameOfTheBook (complete) with SourceTypes=Fakebook to import the complete book for paging through the book or searching a song via PDF bookmarks and an entry ~NameOfTheBook - TOC with SourceTypes=TOC that shows the table of content. And the usual line for each song.
I import via CSV import just the songs I really want to use plus the whole book and the TOC.
The tilde ~ at the beginning of these special song title entries sorts these entries to the beginning of the list on the songs tab, the SourceTypes simplify applying filters.
Take a look into one of the CSV files that I shared in the forum to see an example.

Hi again Mike,
just a follow-up on the image correction.

I've just done some visual comparisons between the before and after PDF files and I found:

1. The corrected file is some 12% smaller (it lost around 9Mb)
   
2. The pages are "clearer" - there is less, umm, "smudging".  I.E the small spots here and there that often appear in less than perfect scans.  This probably explains the smaller PDF.
   
3. The bits that are supposed to be there seem unchanged.  I was expecting a darkening as I get with "Image correction" "Sharpen Image" in the page overlay but this seems not to be the case.
   

Is this consistent with how you've designed the software?

Thanks mate.

Hi itsme,
strangely enough I've used a couple of your CSV files (had to alter them to match page numbers in my particular PDFs) so I've seen the entries you mentioned and how they work.

Nevertheless, I failed to think of using similar entries when I made the CSV for this PDF.  Thanks for the reminder.  Wonder how many times It'll take for me to remember to do it on a regular basis  

Might be time to make a template CSV file...

Thanks mate.

The image correction software is utilizing third party software that does the heavy lifting for correcting images. Among other things, it applies a color filter (so a grayscale page is produced instead of color), and grayscale images use less data than a colored image, which is why your file is smaller after using the image correction. As far as "darkening" the image, if you are hoping to enhance the clarity of the page by darkening text/lines/notes, etc, there isn't an option in the third party software to do that. That's going to require some custom image processing. I have researched this a little as another user asked for this, but it will involve having to use the OpenCV library to apply various algorithms to the image. It's not a trivial effort unfortunately, but it's on my list of things to do once time allows.

Hey Mike,
good to know.

As for the planned update to allow darkening, that sounds good.

Be well mate.

Long press a song to select it on the library screen, then tap "Edit Song" in the action bar. Go to the Files tab, tap the three dots next to the file in the list and tap "Image Correction". MobileSheets is going to need to first render an image for every page in the entire PDF. It then will process every one of those rendered pages to apply the image correction to it. Just be aware that if you do this with a 274 page PDF, for example, it's going to take an extremely long time to process every page.

Hey, Mike!

Does that only work with the regular Android app? I just discovered this function - and it blows away the image correction I've been doing with ABBYY FineReader! However, in my e-ink app, I can't find a way to do a range of pages. I was just sent a dozen songs for a workshop (anywhere from 8-18pp) and I needed to lower the Brightness of ALL of them by 15. Now, one feature request would be a way to type that number, instead of tapping the <minus> sign 15 times. But, even better for me: a way to do all 18 pages of a song without having to adjust each individual page!

It works on Android and iOS (and that includes the e-ink Android version). The default image correction settings will be applied to every page of the PDF being processed, but beyond that, you'd have to process each page individually, as there isn't an option to apply changes to multiple pages at once.

Nuts. <smile>

Is there a way to address the default settings?

[Zubersoft]

For some of the selections, MobileSheets will use the last selection that was made (such as the color filter). For other selections like brightness/contrast, these always default to 0. Which settings in particular are you wanting different defaults for?
