Thanks for that, not of course an easy read though!

Although the specification is now free, it doesn't seem to be possible to download it without giving an email address and mobile phone number to payment company, is that correct?

I have now downloaded a copy successfully using the button below the 'link' payment option: requires registration with address and phone number, but not mobile phone number. A download link is then sent by email.

The complexity of the PDF standard does mean, though, that insight into how an image is saved as a PDF file, or an image is placed on a page, requires significant additional knowledge, which is probably best obtained from other sources such as online resources. While most common image compression options are supported, for example, the title used in the specification is generally the name of the compression method, rather than that of the image format in which it is commonly used.
