pdf-raku / pdf-native-raku Goto Github PK

I am experimentally creating a set of object classes to fully represent the internal structure of a PDF file with the support of native DOM functions. A bit similar to LibXML, but it doesn't need to be as fully featured to become useful.

It will most likely be initially targeted towards construction and serialization. The currently quite slow PDF::Tags serialization is likely to be an early client of this API. I would like to fully delegate serialization.

It might be particularly nice to write object streams.

Parsing of objects may become an eventual target.

Work starting on branch pdf-dom.

Tagged PDF support creates a lot of small simple dictionary objects. The management and serialization of these is adding a lot of overhead. This, for instance is the main reason why Pod::To::PDF::API6 is twice as slow as Pod::To::PDF.

I've begun an experiment to add specialized support for StructElem objects and their serialization to ObjStm (object streams), with the idea of integrating them into PDF::Tags for writing purposes only. Work has just started on branch struct_elem.
