RxAutoImage
for AutoCAD is an ARX-application for AutoCAD and
AutoCAD LT. It combines the power of AutoCAD,
intelligent raster editing technology, raster-to-vector
and vector-to-raster conversions.
For AutoCAD
users, RxAutoImage for AutoCAD offers support for
corporate standards of scanned technical document
processing, a well-known easy-to-use interface and a
short period of training. Versions for AutoCAD LT
2000/2000i/2002/2004/2005 reduce the cost of
implementation of hybrid (raster and vector)
technology.
Raster Correction
Tools
RxAutoImage
for AutoCAD has a variety of tools for quality
enhancement and correction of color, grayscale and
monochrome raster images. There are several filters for
color and monochrome images, color correction,
deskewing, four-point calibration, correction of linear
and non-linear image distortions using the calibration
procedure, crop, image resolution modification,
rotation, and image resizing.
Color Separation and
Binarization of Color Images
Color and
grayscale images can be converted to several monochrome
layers, for editing or raster to vector conversion. The
new version of RxAutoImage for AutoCAD has tools to
create raster objects by rasterizing vector objects to
color, grayscale and monochrome raster, and merge
monochrome raster images with color
ones.
Raster Object Selection and
Editing
The
enhanced technology of the Intelligent Object Selection
allow the creation of selection sets by means of
AutoCAD-like tools - by picking a point; inside
rectangular or polygonal areas; by crossed rectangle or
polygon, by crossed line, etc. Object snapping for
raster objects is available in RxAutoImage for AutoCAD.
It has the same look and feel of the AutoCAD OSNAP
command. The current active snapping method is displayed
as a pop-up marker at the center of the AutoCAD
crosshair cursor. It is possible to combine several
raster object-snapping methods
together.
RxAutoImage for AutoCAD searches for
vector and raster symbols (predefined sets of raster or
vector objects) and replaces them with other predefined
raster or vector objects.
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.
