    I am trying to generate a PDF that contains dozens of small images. This greatly slows down my PDF generation, as PD4ML loads the images serially. Loading the HTML in a web browser is much faster, as all of the images the loaded in parallel. Is there a way to load the images in parallel inside of PD4ML?

    Thanks

    No. PD4ML runs single thread to be compliant with J2EE requirements.

    If you convert HTMLs come from a single source, probably an image pre-fetch to PD4ML internal cache could help.

    Do you have any example code of how this may be done?

    The simplest way would be to generate an HTML index of the images:

    [language=xml:idlam7vh]

    …[/language:idlam7vh]

    and let PD4ML to convert it to PDF once.
