    You will need to write a text layout engine and then using the layout information that you’ve produced, output the necessary PDF constructs.

     

    In order to do that, of course, you will need the font metrics.

     

    And at some point you will need to learn about font embedding, and then subsetting, and then encodings, and then ….

     

     

    Now you can see why we recommend that you use an existing PDF library instead of writing your own. You are just wasting your time…

    You have to do this manually. That is just one reason why it's in general a

    bad idea to create PDF files from scratch: You have to process all the font

    metrics yourself and find out how wide your text will be, and then position

    it accordingly on the page. When you use a PDF library or framework, that

    is usually done for you (or at least there are ways to get to that

    information in a much more user/programmer friendly way).

    Thanks Irosenth,

     

    thanks for your quick reply again

    actually, Its waste of time n waste to resources may be..but we are developing a serviced based product in which a small part of pdf comes.

    we almost developed own pdf developer for HTML5 ,Yes it is not 100% developed and correct.

    just integrating some features which are as per our need.

    by the way thanks for Font embedding hint.. I will work on that surely,

    thanks again...

    Details on Font Metrics are in the PDF standard as well as the various specs for each font format.
