Operation Manual

582 | CorelDRAW X8 User Guide
• For best results when you use the Centerline Trace method, convert the bitmap to the black-and-white color mode before tracing. Note
that in this case you cannot adjust detail.
• When tracing technical illustrations and sketches with faint lines, you can improve the results by applying the Find edges special effect to
the source bitmap. To do this, click Bitmaps Contour Find edges.
• For outline tracing, reduce the color depth of the bitmap by changing the color mode, and then adjust the color and contrast.
• You can adjust the traced results at any time, including during a trace, by changing the PowerTRACE settings.
•
To trace a specific area in a bitmap, use the Shape tool to define the area before clicking Bitmaps Trace bitmap.
• If important detail has been removed from the traced results, you can disable the Remove background check box on the Settings page
of PowerTRACE. You can also try enabling the Specify color option on the Settings page and sampling the color you want to specify as a
background color.
• If background color is removed around the edges but remains within image areas, enable the Remove from entire image check box.
• If too many colors or details are lost, move the Detail slider on the Settings page.
• To preserve detail in bitmaps that have fine details, thin lines, and no anti-aliasing applied, choose Line art from the Type of image list
box on the Settings page.
