Raster-to-Vector Conversion
RxAutoImage
for AutoCAD recognizes and converts to
AutoCAD vector objects, raster lines,
arcs, circles, polylines, symbols, text
and hatches. Raster to vector conversion
is possible using either tracing or
automatic raster to vector conversion.
Tracing
(Interactive Raster-to-Vector
Conversion)
To convert
a raster symbol, line, arc or circle to
a vector object it is necessary to pick
a point on the source raster object.
There are several options for how to
treat the source raster object - to
delete or to keep it. To convert raster
hatching to a vector object it has to be
crossed by a selection line. Arbitrary
curves are converted to AutoCAD
polylines. A color and grayscale image
has a reduced set of primitives to
convert to vector. They are: polylines,
lines, arcs and circles.
Many
technical drawings contain conventional
graphic symbols: maps, plans, electric
circuits, hydraulic and processing
schemes. The symbol recognition of
RxAutoImage for AutoCAD is based on an
expert system. It is possible to train
the program to recognize any graphic
symbols, make a selection by picking,
search and replace, and convert raster
symbols to vector blocks and symbols.
Raster symbols may differ from the
specified template by orientation and
scale, and the program will
automatically define the required
parameters for inserting the vector
block.
Automatic
Raster-to-Vector Conversion (PRO version
only)
When
applying automatic vectorization, the
user needs to set parameters and then
start the procedure. It is the program
that defines which raster lines can be
presented as lines, arcs, and which of
them are raster texts. RxAutoImage for
AutoCAD can recognize not only graphic
entities - lines, arcs, circles, but
also texts, symbols, and hatches. Object
properties such as width, line type,
size arrows are also preserved.
Automatic correction of vector drawings
is provided: joining the ends of contour
objects, line orthogonalization in a
specified direction, rounding objects
width to specified values. Users can
choose to place objects with different
widths onto different vector layers, and
highlight them with color.
Text
Recognition (PRO version only)
During
automatic raster to vector conversion
RxAutoImage for AutoCAD Pro locates
raster texts and converts them to
AutoCAD text entities. The user can
choose the output text representation.
It is possible to store the results as
text or convert them to polylines or
outlines. The user can train the OCR
module to recognize raster texts of any
type. After applying automatic
vectorization, you can review and
correct the obtained texts in an
interactive mode.
As an optional extra, we can offer a
professional multi-language OCR module
to recognize text fragments and text
documents.
