PDF OF IMAGE NOT LEGIBLE

[Fred22142441qk69]

I have been using this Sheet Music PDF for over a year and now all of a sudden 2 pages are not legible!!

What is wrong?? This has happened in 3 separate files. 

Will this happen to all my sheet music PDFs?

What software do you use to display this PDF? On what device? I assume you did not modify the PDF knowingly. Is it always the same pages in different PDFs that are rendered this way? Does it make a difference if you zoom in?

I did not modify.. no effect if zoomed in. Not always same pages in all the broken PDF. 

I use an iPad Pro 12 running ForScore - an app to display music sheets and turns the page by facial gesture or foot pedal.

This problem just started. Not all PDFs are affected - only a few. Some have only 1 or 2 pages out of many that are affected. 
The majority of PDFs I have created with Photoshop or Acrobat 9 Pro. 
Here is Silent Night PDF. It is totally affected. Wait! I can't attach a PDF1

HOW CAN I DO THAT?'

What happens when you display the PDF file in Adobe Acrobat or Adobe Reader on your computer? Does it show the same effect? If not, then the problem is with ForScore, and you will have to work with their suppor to figure out what's going on.

Did you create the original PDFs? If so, how? If not, where did they come from? can you attach an original PDF?

You can attach PDFs by clicking here: (see attached screen shot)

Have you contacted ForeScore help yet? I expect other users may have run into the same issue.

If your original files are scans of sheet music, you might see an improvement by optimizing your PDF (File> Save-as-other> Optimized PDF) before importing it into ForeScore, but which settings to choose would be a guess. Here's my guess: (see 2nd screen shot).

Also, check for iPad and ForeScore updates.
