pdflib, load an image from file pointer

[Anon]

I'm generating pdf's on the fly with pdflib.
Datas are stored in a PostgreSQL db and images are also in the db but in LARGE OBJECTS...

I would like to put an image from the database in a pdf ...

I found this :

int pdf_open_image (int PDF-document, string imagetype, string source, string data, long length, int width, int height, int components, int bpc, string params)

BUT --> with large objects in postgres I don't have a filename for the image but a pointer

Pffff
