PDF wrapper for FileOptimizer (Python)

2016-10-29T20:22:27-07:00

Python recipe 580711 by Harald Lieder (fileoptimizer, fitz, mupdf, optimization, pdf, pymupdf).

Among dozens of other filetypes, FileOptimizer also compresses PDFs - often significantly. The issue is that the used plugin smpdf is free for non-commercial use only and it annoyingly also overwrites metadata information to state this.

The following tool remedies these metadata changes (but not the license situation!).

Add function to Python's builtin module through C API (C)

2015-10-16T12:11:58-07:00

C recipe 579110 by airween (api, builtins, c, exten, python).

Add function to __builtin__ module through C API

Sometimes it need to embedding a Python script to a C code, and it references to a function, which also provided by the same C code. Then you have to import the module, as you defined in your C code.

But this import would be skipped, if you add your function to your __builtin__ module. In Python3 (3.5), there is the PyModule_AddFunctions() function, but in the previous versions, you can make it like this snippet.
