Description

I have a custom COSWriter which compresses all streams and runs a SHA1 sum over each object, only writing one instance of each object with the same SHA1 sum.

This really helps compress PDFs.

I use this by calling MyCustomCOSWriter.write(PDDocument);

The trouble is that I have no way of calling the font subsetting that happens in PDDocument.save().

Could we have a method to perform that font subsetting manually?
