You are having the following issues with a specific file or group of files:
- An error message appears reading: “Object reference not set to an instance of an object.”
- Certain markups/tools don’t work in a specific PDF.
One of your files, or group of files, may be corrupted. Common causes of file corruption include:
- PDF conversion. Certain PDF converters produce low-quality PDFs.
- Uploading or saving a PDF. File corruption can occur when another system process interrupts the saving or uploading of a PDF.
Recreating a PDF serves as a general solution for fixing file-specific corruption issues. It generates a new PDF around the original content while clearing the file of most instances of corruption. You will then be able to re-import your markups onto a new PDF.
To recreate a PDF:
- Make a copy of the affected PDF(s).
- Open the copy in Revu.
- Delete any markups on the PDF (if present). To delete your markups:
- Open the Markups List (Alt+L).
- Select a markup from the Markups List , then press Ctrl+A to select all markups.
- Press Delete on your keyboard to clear all markups from the PDF.
- Save the copy by pressing Ctrl+S, then close the file.
- Go to File > Create > From File. The File Explorer window appears.
- Select the same copy and click Open. The Save As dialog box appears.
- Click Save. The file is recreated.
- If you had markups on the original PDF, you will need to re-import them:
- Go to Markups List > Markups > Import. The File Explorer window appears.
- Select the original PDF file and click Open.
The newly generated file will now have all of your markups.
We recommend using the Bluebeam PDF Printer or the Bluebeam plugin whenever generating PDFs from the source files. This will ensure high-quality PDF creation and prevent many file-specific issues from occurring.
