> Hi,
> I am working on extracting images from a PDF using pdfbox version 2.0.34.
> While doing so we have our own recursive logic to recurse through all
> PDResources for each page and within each page we check for all the objects
> to filter out images. This recursive logic has a max depth of 25 to avoid
> infinite recursion.
> When trying out the image extraction for the same PDF using the CLI, the
> image is extracted within a second indicating that the image extraction logic
> within the pdfbox source code is handling image extraction using an
> ImageGraphicsEngine defined within the source code.
> Can you help me understand:
> * To handle image extraction, are there are any API directly provided by
> PDFBox?
> * Is there any way to reuse the image extraction logic within the source
> code i.e is it exposed as a public API?
> * Any other suggestions to handle image extraction gracefully with/without
> recursion?
