This header file collects some general-purpose macros (and static inline functions) that are used in various places.

The DXF backend of Potrace.

The Postscript backend of Potrace. This can produce "ps" or "eps" output, and different kinds of graphical debugging output. Postscript compression is optionally supplied via the functions in flate.c.

The GeoJSON backend of Potrace.

The PDF backend of Potrace. Stream compression is optionally supplied via the functions in flate.c.

The PGM backend of Potrace.

The SVG backend of Potrace.

The xfig backend of Potrace.

figure out the true bounding box of a vector image

Routines for manipulating bitmaps, including reading pbm files.

bitmap input/output functions

bits.h: this file defines some macros for bit manipulations. We provide a generic implementation, as well as machine- and compiler-specific fast implementations

private part of the path and curve data structures

the PostScript compression module of Potrace.

This tells Alpha OSF/1 not to define a getopt prototype in <stdio.h>. Ditto for AIX 3.2 and <stdlib.h>.

Routines for manipulating greymaps, including reading pgm files. We only deal with greymaps of depth 8 bits.

code for adaptive ompression, as used in PostScript.

this header file contains some platform dependent stuff

A simple and self-contained demo of the potracelib API

operations on potrace_progress_t objects, which are defined in potracelib.h.

functions to render a progress bar for main.c. We provide a standard and a simplified progress bar.
