Serves images from pages of a PDF file.
This is an HTTP server that only reads PDF files, and serves images from individual pages.
This application is useful if you have a PDF file that can be treated as merely a container for images.
The most useful format of the PDF file will be where each page simply has an image object as its contents.
Then, given a URL with page
query parameter as a page number, this application will serve the (first)
image object from page number page
. If the object is a JPG, it is returned as-is. Otherwise, it is
rotated (if necessary) and converted to a PNG image.
