potrace 1.7 (3.1.2007)

Short:        potrace - raster bitmap to SVG converter
Author:       Peter Selinger
Uploader:     info ar-kleinert de
Type:         gfx/conv
Version:      1.7 (3.1.2007)
Replaces:     gfx/conv/potrace-mos.lha
Architecture: m68k-amigaos >= 3.1.0; ppc-morphos >= 1.4.5

 This is a quick port of "potrace" (bitmap to SVG converter)
 for MorphOS. There two different 68k versions included
 as well for AmigaOS & WinUAE.

 Please note, that:

  - the 68k versions do not run under MorphOS,
    they will crash the emulation
  - they run under WinUAE however
  - the 68k version compiled with SAS/C is not
    included, since it does crash with both emulations
  - so please use the PPC .elf version under MorphOS

 Main changes:

  - added smakefile & SCOPTIONS for SAS/C
  - added makefile for VBCC
  - added makefile for GCC 2.95.x of MorphOS
  - added proper config.h for use with all three both
  - added three test batch files and this readme
  - created a "bin" folder for the binaries
  - fixed bug in potracelib.c with the help of Frank Wille
    (I was under impression that it'd be a VBCC bug, so
     he got involved)
  - fixed three more bugs (one in auxiliary.h and one
    in two other source files where a "static" was missing
    in a function declaration - feel free to do a "diff" to v1.7)

 Usage of the tool is explained in the README - for good results
 also have a look at the two test batch files.

 Enjoy.

           POTRACE - transform bitmaps into vector graphics

                                * * *

DESCRIPTION

 Potrace is a utility for tracing a bitmap, which means, transforming
 a bitmap into a smooth, scalable image.  The input is a bitmap (PBM,
 PGM, PPM, or BMP), and the default output is one of several vector
 file formats.  A typical use is to create EPS files from scanned
 data, such as company or university logos, handwritten notes, etc.
 The resulting image is not "jaggy" like a bitmap, but smooth. It can
 then be rendered at any resolution.

 Potrace can currently produce the following output formats: EPS,
 PostScript, PDF, SVG (scalable vector graphics), PGM (for easy
 antialiasing of pixel-based images), and XFig. An experimental
 Gimppath backend is also provided. Additional backends might be added
 in the future.

 A separate program, mkbitmap, is also provided. This program can act
 as a pre-processor for potrace, applying scaling and various filters
 to an image before converting it to a bitmap. This is useful for
 potracing greyscale and color images.
