Version 1.0 (February 28, 2018)
Initial release of new command-line application that scans for and detects PDF error and warning conditions for Windows and Linux 64 systems:
- Cannot open file. The PDF document is not a valid PDF, or is too damaged to open or process.
- The PDF requires password for opening, and a password was not provided.
- The PDF contains an owner password.
- The PDF is an XFA document.
- The PDF document is a PDF 2.0 file.
- The PDF uses fonts not embedded in the file.
- This PDF contains annotations.
- This PDF contains annotations that do not have normal appearances.
In working with PDF Checker, a user can:
- Provide a password on the command line, so that the software can process a PDF document that is password protected.
- Save the results of the review for a PDF document to an output text file.
- Configure a JSON profile file that holds settings for PDF Checker to use when reviewing PDF documents.
Product can scan for and detect the following PDF error and warning conditions, and determine if the document contains the following items:
- owner password
- low / high resolution images
- images compressed with JBIG2 / JPEG2000
- 16-bit / 32-bit color images
- alternate images
- fully embedded fonts
- fonts that are not embedded
- embedded files
- page thumbnails
- application private data
- suboptimal compression used for objects (LZW, ASCII85, RLE; or no compression)
- digital signatures
- annotations marked not for viewing / printing
- layers (optional content)
Product installed to default location “Program Files/Datalogics/PDFChecker.”
User license agreement is included with the installation process.
Configurations included in a JSON profile file, and a default JSON profile is provided called everything.json, with all checks turned on by default.
Program looks for the JSON profile file in the Profiles subdirectory first. If the profile is not found there, the program looks for it in the current working directory.
