Hello PDFBOX users,

You like PDFBOX and want to make it better? You want to confront 
developers with new bugs? You want to influence this chart?
https://issues.apache.org/jira/browse/PDFBOX/?selectedTab=com.atlassian.jira.jira-projects-plugin:summary-panel
Here's how:

1. Go to
https://repository.apache.org/content/groups/snapshots/org/apache/pdfbox/pdfbox-app/2.0.0-SNAPSHOT/
2. Download the latest .jar file from there. (There is no need to use 
the 1.8.x version, because that branch has font and color problems that 
are already known and solved in the 2.0 version)
3. Launch PDFReader like this:
java -jar pdfbox-app-2.0.0-20140322.150820-239.jar PDFReader
A not-very-comfortable viewer will appear.
4. Download one or more of the images from here: 
http://acroeng.adobe.com/wp/?page_id=108
5. Open an image with the PDFBOX viewer
6. Open that image with the Adobe Viewer
7. Compare both visually, set the % in the Adobe Viewer so that they 
have the same size.
8. If the images are not identical, post it here. Optionally: open an 
issue in JIRA.
9. If the images are identical, post it here too, so that there is no 
double work. Always quote the files that others have already tested.
10. Repeat at 4 as long as you like.

The file DeviceN3.pdf has already been tested.
