RELEASE ANNOUNCEMENT:
DEMONSTATION PROGRAM OF SILHOUETTE VERSION 1.0
Requirements: ST/TT system with at least 1 megabyte (2M recommended) of
RAM. ST high resolution on the ST or TT supported. Please
read the accompanying text file.
Atari Users,
Its ready but let me be the first to say (before Ralph or Ron, etc.)
that its quite late in arriving. My apologies and especially to a few
that have patiently waited (your copies will be arriving in the mail).
I wish Silhouette had been completed a year earlier. I would have treated
myself to a nice vacation. As things stand now I look forward to catching
up with some bills.
Silhouette began as a project to create an auto-tracing program for
the Atari ST. In the course of developing the tracing algorithms I
realized that there would not be a perfect solution, i.e. perfect auto-
tracer, at least not within a reasonable amount of time. Therefore,
it was necessary to develop the auto-tracing routines around a drawing
program that would allow the user to load bit images and prepare them
for auto-tracing. Also the ability to auto-trace and then spruce up
the auto-trace would be of great value. The result is a drawing program
with some unique drawing features for creating bit image and vector
graphics. The auto-tracing feature links the two graphic types together.
The auto-tracing of Silhouette works best with line art. It will
not attempt to determine the type of fill patterns existing and then
replace them with a vector graphics fill pattern. Silhouette will
auto-trace graphics and offer several degrees of variability in how
it is processed. One can output a raw trace which might be of value
for very small objects or for objects with many horizontal and vertical
lines. Or one can output an auto-trace with GEM 2.0 bezier curves
which are loadable by the high-end desktop publishing programs. Maxwell
was approached by several sign-makers interested in a auto-tracer and
with the bezier output, the auto-tracing function will be of great
value. When spline auto-tracing is selected Silhouette will seek out
the important points in the trace, points at corners or points that
help define the curvatures of the image.
Output of the auto-trace is sent directly into the vector
graphics window along with a gray shaded bit-image of the trace area.
One can adjust the control points of the polylines or splines while
referencing the bit-image in the background. The polyline editing
function was developed to speed up editing. One can move from control
point to point by simply hitting the keys 'Q' or 'E' and add or delete
points with the keys 'A' or 'D'.
You might find some of the operations in Silhouette unorthodox
but in the short term you will find out why they work as they do.
Most every function begins with a single left mouse button click.
No need to maintain the mouse button down while drawing or editing.
This frees up the hand motion and allows for smoother motion of the
mouse. Operations are terminated with right mouse button click or
by hitting the ESCAPE or UNDO key to cancel. Objects in the raster
or vector windows can be deleted with the ESCAPE or UNDO key too.
Movement of whole objects, while being drawn, is accomplished by
depressing and left mouse button during the move.
Let me describe the main features in version 1.0.
* Auto-tracing : Raw or splined auto-tracing with adjustable
parameters. Background bit-image display.
* Drawing tools: clipper, freehand, line, polyline, circle, ellipse,
elliptical arc, circular arc, polygons, stars,
parabolas, spray can, text (supports FSM GDOS),
pixel editor tool.
* Smoothing: B-splines, Bezier curves. Convert polylines into
either splines and visa-versa. Convert Circles or
Ellipses into bezier curves (GEM 2.0 format).
Multi-point or 4 point (GEM 2.0) beziers supported.
* Magnification: Magnify the vector window image up to 16 times.
Drawing resolution achieves up to 3200 DPI.
* Graphics
Input: Bit image formats IMG, DEGAS, TINY, MACPAINT. Vector
graphics GEM format.
* Graphics
Output: Bit images as IMG files. Vector graphics as GEM
meta files or DXF universal CAD format.
* Clipboard: Two clip buffers for the raster (bit-image) graphics.
Separate cut and copy buffers for vector graphics.
Will accumulate copied or cut objects. Clip buffers
save to disk and can be re-loaded during future
sessions.
* Duplicate,
Reshape : Duplicate vector objects in three ways (freehand,
radial or cartesian). Reshape objects in several
ways: size, stretch, free corner warp, skew
(parallogram), skew (trapezoid).
* Rotate: Rotate polyline objects to a 1/10th of a degree.
* Splice and
Cut: Splice and cut polylines.
* Data: Object information is continuously updated on the
information line while an object is being created.
The bit-image and vector window are size adjustable.
* Quick
Keys: Operate Silhouette with a set of quick key controls.
* Manual: 100 page manual in a three ring binder and slip
cover.
* Hardware
Support: Operates on the ST, STacy and TT. 1 megabyte
required but 2 megabytes recommended. ST high
resolution supported on the ST and TT.
* GDOS Supports the old GDOS and new FSM GDOS.
