./graphics/potrace, Utility for transforming bitmaps into vector graphics

[ CVSweb ] [ Homepage ] [ RSS ] [ Required by ] [ Add to tracker ]


Branch: CURRENT, Version: 1.14, Package name: potrace-1.14, Maintainer: adam

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, 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.

Log message:
Updated potrace to 1.14.

February 19, 2017: Release 1.14

 This release consists of bugfixes and minor portability improvements.
 A number of bugs triggered by malformed BMP files have been fixed,
 including CVE-2016-8685 and CVE-2016-8686. Error reporting has been
 improved. The image size is now truncated when the bitmap data ends
 prematurely. It is now possible to use negative dy in bitmap
 data. Portability has been improved to encompass C++11. The default
 compiler is now clang if available. Thanks to Nelson Beebe and Martin
 Gieseking for reporting portability issues, and to Agostino Sarubbo
 for reporting bugs.

Log message:
Release 1.13
Some critical bugs in the processing of BMP files were fixed. These
bugs allowed the program to be crashed, or potentially to be abused
in other ways, by feeding it specially crafted BMP files. Thanks to
Tomasz Buchert and Agostino Sarubbo for reporting these bugs.
Portability was improved for C99 and for MSVC++. Thanks to Peter
Breitenlohner, Nelson Beebe, and Martin Gieseking for reporting
portability issues.

Update to 1.11:

February 19, 2013: Release 1.11

 A GeoJSON backend was added; thanks to Christoph Hormann for
 contributing this. Support for bitfields in the BMP format was
 added. A minor change was made to the behavior of the alphamax
 parameter; a value of 0 now gives a true polygon.

This package was broken at least on NetBSD, since it didn't install
the libpotrace library needed by the potrace executable.

Convince the package to install the library.
