PowerTRACE lets you perform the following adjustments to fine-tune your trace results.
You can adjust the amount of detail in the traced result and smooth curved lines. When you adjust detail, you change the number of objects in the traced result. If you used the Outline Trace method to trace the bitmap, adjusting the traced result also changes the number of colors. Smoothing changes the number of nodes in the traced result. You can also control the appearance of corners in the traced result by setting the threshold for corner smoothness.

By default, the source bitmap is preserved after being traced, and objects in the traced result are automatically grouped. You can have the source bitmap automatically deleted after the trace is complete.
You can choose to remove or preserve the background in the traced result. With the Outline Trace method, you can also specify the background color to be removed. If the background color around the edges is removed but some background color still shows through some areas of the image, you can remove the background from the entire image.
By default, object areas that are hidden from view by overlapping objects are removed from the traced result. You can choose to keep the underlying object areas. This feature is useful for traced results that will be output to vinyl cutters and screen printers.
To reduce the number of objects in the traced result, you can combine adjacent objects of the same color. You can also group objects of the same color so that you can manipulate them more easily in Corel DESIGNER.
You can adjust the settings in PowerTRACE and retrace a bitmap as many times as necessary until you are satisfied with the result. If you make a mistake, you can undo or redo an action, or you can revert to the first traced result.
To fine-tune traced results |
1. |
Select a bitmap.
|
2. |
Do one of the following:
|
• |
Click Bitmaps Centerline trace, and click a command.
|
• |
Click Bitmaps Outline trace, and click a command.
|
3. |
On the Settings page, move any of the following sliders:
|
• |
Detail — lets you control the amount of original detail that is preserved in the
traced result. Higher values maintain more detail and result in a greater number
of objects and colors; lower values discard some detail and result in fewer objects.
|
• |
Smoothing — lets you smooth curved lines and control the number of nodes in
the traced result. Higher values result in fewer nodes and produce curves that do
not closely follow the lines in the source bitmap. Lower values result in more
nodes and produce more accurate trace results.
|
• |
Corner smoothness — This slider works in conjunction with the Smoothing
slider and lets you control the appearance of corners. Lower values maintain the
appearance of corners; higher values smooth corners.
|
You can also access PowerTRACE from the Trace bitmap flyout button on the
property bar.
