SUMMARY="Utility for tracing a bitmap"
|
|
DESCRIPTION="Potrace is a tool 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), DXF, GeoJSON, PGM \
|
|
(for easy antialiasing of pixel-based images), Gimppath, and \
|
|
XFig. 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.
