Contour Find edges.The following tips can help you achieve high-quality trace results.
| • | Use high-quality source bitmaps. If dithering or JPEG compression was used in the source bitmap, the bitmap may contain additional noise. For best traced results, remove the noise before tracing the bitmap. |
| • | 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. |
