[opencms-dev] Remove metdata from PDF on upload

[Michael Emmerich]

Tobias,

without having done this my idea would be the following:

Extend the org.opencms.file.types.CmsResourceTypeBinary with you own 
class. There, overwrite at least the createResource method and check if 
the file is a PDF. If so, use PDFBox to modify the binary content and 
then call the super method of the createResource method with the 
modified content.

Take a look at the CmsResoruceTypeImage as an example how to modify the 
binary content in the createResource method.

You must then modify the opencms-vfs.xml to use your own class for the 
resource type "binary".

This is not tested, but i think it should work.

Bye,

Michael
