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.
