Thanks Andi!
I was able to build a pdfbox wrapper with your changes, too. The changes
to setup.py makes it much easier to get the script working. Good work!
As a JCC and Java newbie I didn't understand the difference between
--jar, --include and --classpath at first. Could you please extend the
README in order to explain the three options?
Today I've started to play with subclassable Python wrappers. I couldn't
get the appended example to work. I run into several issues like
"SystemError: NULL result without error in PyObject_Call". Could you
have a look, please? The jar with PyPDFTextStripper was wrapped together
with the pdfbox jar.
public class PyPDFTextStripper extends PDFTextStripper {
private PDDocument document;
private long pythonObject;
public PyPDFTextStripper(String filename) throws IOException
{
System.out.println( "Loading: " + filename );
document = PDDocument.load(filename);
List allPages = document.getDocumentCatalog().getAllPages();
startDocument(document);
for( int i=0; i<allPages.size(); i++ )
{
PDPage page = (PDPage)allPages.get( i );
System.out.println( "Processing page: " + i );
PDStream contents = page.getContents();
if( contents != null )
{
processStream(page, page.findResources(),
page.getContents().getStream());
}
}
}
public void pythonExtension(long pythonObject)
{
this.pythonObject = pythonObject;
}
public long pythonExtension()
{
return this.pythonObject;
}
public void finalize()
throws Throwable
{
pythonDecRef();
}
public native void pythonDecRef();
public native void processTextPosition( TextPosition text );
public native void startDocument(PDDocument pdf);
public native void startPage(PDPage page);
}
pdfbox.initVM(classpath=pdfbox.CLASSPATH)
class Stripper(pdfbox.PyPDFTextStripper):
"""
"""
def processTextPosition(self, text):
print text
def startDocument(self, doc):
print doc
def startArticle(self, isltr):
print isltr
