What Is the Mechanism of Creating PDF?

Create PDF: All You Need to Know

But that's more about how your format is generated… not too much how you actually encode the data. It really varies from application. Even in the most simple cases, you'd have to figure out some parsing algorithm yourself to determine if your input is a file, an audio stream, a vector of pixels, or other kind of data structure. So instead of doing all of that work for you, you'd probably just use an existing format that has all the features you need. As I noted, that kind of flexibility is very important — we don't just want to sit down and write all the metadata that would be necessary for every kind of media type. We want to be able to do that automatically. At the very least, a media format should do that, and for many media types this is not the case. There's a lot that could be.
