blank/partially rendered PDF pages - limitations on max page size

If you have a PDF doc with very large pages, then you may find that it only partly renders or is completely blank, depending on the PDF viewer you are using.

The PDF specification :

"The minimum page size should be 3 by 3 units in default user space; the maximum should be 14,400 by 14,400 units."

Can draw up to 14000 units in height, per page.

If the dpi used is 72, then each inch we use 72 units.

Therefore the maximum size is 14400/72 = 200 inch

More recent version of PDF:

- the document DPI can be changed (version >= 1.6)

workaround: lower the resolution to get a bigger document.

at the cost of accuracy.

  

So, in theory cannot draw a PDF v < 1.6 with a page height > 200 inch.

Google Chrome's PDF reader seems to be not following the specification as it allows to have a bigger size.
