These settings are used by the Graphics - Art Trace tool when converting a bitmap image into vector geometry (lines, arcs, circles, Bezier curves etc.) The settings determine how the data is to be translated (median filtering, conversion to monochrome, vector conversion, geometry creation and output).
Name
Enter a unique name for these settings.
Description
Enter an optional description.
ArtTrace - Image Processing
Image Processing
Median Filtering
Switch this option on to remove noise from the source image.
Black & white conversion
Colour Channel
From the pulldown list choose Luminance, Grey, Red, Green, Blue or Transparency.
Intensity Threshold
Enter the required value as a percentage.
ArtTrace - Vector Conversion
Edge-Detection
Choose which edge detection method to use.
- Search for outlines
- Search for centre-lines - in this case enter the maximum line width in pixels
Tolerance
You can also set the tolerance for the conversion process. This will determine the maximum deviation from the source data.
Tolerance
Enter the required value in pixels.
ArtTrace - Geometry
Output Types & Smoothing
Here you can determine the type of output and specify whether or not the Smoothing tools will be called automatically when the conversion process is complete.
- Generate lines only
- Generate lines, arcs and circles
- Generate smooth curves- in this case you should also specify the following values:
- End to end tolerance
- Maximum deviation
- Angle tolerance
- Generate Bezier curves
Run smoothing tool on output geometry
Switch this option on if required.
ArtTrace - Output
Position
Here you can determine how the vector geometry will be positioned/scaled:
- Place over the graphic entity
- Place manually (after wizard is closed) - you will be asked to Identify base point
Place result into a block
Switch this option on to place the generated vector geometry into a separate block.
Name
Enter the required block name.
Add Image with generated entities
This option will add the graphic image to the current layer as well as the vector entities
