DESCRIPTION


The autotrace program accepts bitmap graphics from the file inputfile specified on the
command line, and as output produces a collection of splines approximating the original
image, the converting the image from bitmap to vector format. It behaves in a manner
similar to the commercial software known as *tream*ine or *orel*race. The result is sent
to standard output unless the -output-file option is active.

OPTIONS


Options can begin with either -- or -. Any unambiguous abbreviation can be used for the
option name. Option names and values can be separated with either a space or equal sign
(=).

-background-color hexvalue
Employ the color specified by the hexadecimal code hexcode as the background that
should be ignored, for example FFFFFF (default: no background color).

-centerline
Trace an object's centerline (default: employ its outline).

-color-count int
Reduce the bitmap to using the number of colors specified by the unsigned integer
int (range: 1-256). The default value of 0 indicates that no color reduction is to
be done. Does not work with grayscale images.

-corner-always-threshold angle
Consider any angle at a pixel which falls below the specified angle (in degrees) as
a corner, even if it is bordered by other corner pixels (default: 60).

-corner-surround int
Consider the specified number of pixels on either side of a point when determining
if that point is a corner (default: 4).

-corner-threshold angle
Consider any pixel which forms an angle with its predecessor(s) and successor(s)
that is smaller than the specified angle (in degrees) as a corner (default: 100).

-despeckle-level int
Employ the specified integer (range: 1-20) as the value for despeckling (default:
no despeckling).

-despeckle-tightness real
Employ the specified real number (range: 0.0-8.0) as the value for despeckle
tightness (default: 2.0).

-dpi int
The dots per inch value in the input image, affects scaling of mif output image.

-error-threshold real
Subdivide fitted curves that are offset by a number of pixels exceeding the
specified real number (default: 2.0).

-filter-iterations int
Smooth the curve the specified number of times prior to fitting (default: 4).

-help Print a help message and exit.

-input-format format
Employ the specified input format, where format is one of:

BMP (Windows bitmap format)

PBM (Portable BitMap format)

PGM (Portable Graymap format)

PNM (Portable Anymap format)

PPM (Portable Pixmap format)

TGA (Targa format)

The supported input formats are determined when the application is built and depend
upon the availability of other software (the -list-input-formats command can be
used to determine which are supported locally).

-line-reversion-threshold real
When a spline is closer to a straight line than the specified real number weighted
by the square of the curve length (default: .01), maintain it as a straight line,
even if it is a list with curves.

-line-threshold real
If a spline does not deviate from the straight line defined by its endpoints by
more than the specified number of pixels, then treat it as a straight line
(default: 1).

-list-input-formats
Send a list of the supported input formats to stderr.

-list-output-formats
Send a list of the supported output formats to stderr.

-log Send a detailed progress report to the file inputfile.log.

-output-file file
Send the output to the specified file.

-output-format format
Employ the specified output format, where format is one of:

ai(Adobe Illustrator)

cgm(Computer Graphics Metafile)

dr2d(IFF DR2D format, used almost exclusively on Amiga platforms)

dxf(AutoCAD Drawing Exchange format)

emf(Windows Enhanced Metafile format)

epd(Encapsulated Vectorial Graphics format)

eps(Encapsulated PostScript)

er(Elastic Reality Shape format)

fig(xfig (1) 3.2)

mif(FrameMaker MIF format)

pdf(Portable Data Format)

p2e(pstoedit (1) frontend)

sk(Sketch)

svg(Scalable Vector Graphics)

swf(Shockwave Flash 3)

The supported output formats are determined when the application is built and
depend upon the availability of other software (the -list-output-formats command
can be used to determine which are supported locally).

-preserve-width
Whether to preserve line width prior to thinning.

-remove-adjacent-corners
Remove adjacent corners.

-report-progress
Report tracing status in real time.

-debug-arch
Print the type of cpu.

-debug-bitmap
Dump loaded bitmap to <input_name>.bitmap.

-tangent-surround int
Consider the specified number of points to either side of a point when computing
the tangent at that point (default: 3).

-version
Print the version number of the program and exit.

-width-factor real
Weight factor for fitting the linewidth.
