Re: Custom TextStripper / PDGraphicsState Not Reading Color
Hi All
Just to follow up on this thread, I haven’t yet removed the .properties functionality.
However, it has now become not just desirable but necessary, as PDFBOX-2358 has shown that PDFBox is not handling resource loading in an OSGI compatible manner.
Basically, a class shouldn’t load resources from other packages, which means that the mechanism for overloading operators via .properties isn’t safe in subclasses. The PrintImageLocations in the “examples” package breaks this rule with the following code:
public PrintImageLocations() throws IOException
{
super( ResourceLoader.loadProperties(
"org/apache/pdfbox/resources/PDFTextStripper.properties", true ) );
}
Because it’s loading resources in the “pdfbox” package. What this also means is that nobody can subclass the built-in PDFBox classes and safely load the built-in PDFBox .properties.
I’m going to migrate the .properties to the existing registerOperatorProcessor() mechanism.

The problem is not that we don’t have the mechanism, it’s that we’re using .properties files at all. The list of operator’s can’t be controlled from both code and from .properties lists, one source has to be authoritative - otherwise we’d end up with a situation where we have an operator disabled in a .properties file and then re-enabled in code. Currently we have a situation where that could happen.

It’s important to note that it’s very, very unlikely that anybody is using the .properties files in a use-case where they are not also making some code changes, so the supposed benefit of “not having to recompile” never existed. Adding an operator would always require compile-time changes to PDFBox so that the PDFStreamEngine subclasses actually does something with the new operator.
