Using pdfimport extension from UNO

[dvandersluis]

I am trying to open a PDF file using the pdfimport extension from UNO, in order to be able to convert it to an HTML file. However, I cannot seem to get the file to open as a "Hybrid PDF/ODF" as mentioned in the extension documentation; rather it opens as a drawing file, no matter what I do. Whether I try calling desktop.loadComponentFromURL with no Arguments or with a FilterName = writer_pdf_addstream_import PropertyValue argument, the document supports the "com.sun.star.drawing.DrawingDocument" service.

Furthermore, if I try to export the Drawing to HTML, I get a Com::Sun::Star::Task::ErrorCodeIOException. I have no problem exporting a writer format (doc, odt, docx, etc.) to HTML with the same code.

Can anyone help me get the PDF opened in writer or exported without an error? Thanks!
