Tracing Bitmaps

The Trace Bitmap command traces bitmap objects and picture objects (images which have been imported with the PICT as Picture command). It creates a group of vector lines from the image.

To trace a bitmap or picture object:

1.	Select the image to trace.

2.	Select Modify > Trace Bitmap.

3.	Enter the desired criteria in the Trace Bitmap dialog box.

 

Parameter	Description
Maximum width in pixels	Specify the maximum number of pixels to be recognized as a single line; pixel counts above the selected value are traced
Collinearity Sensitivity	Select a value to define the segment size and accuracy of the trace

4.

Click OK.

The time it takes VectorWorks to trace the image can vary from seconds to hours. The tracing time required is determined by the image size, as well as the line threshold and collinearity sensitivity settings selected.
