Setting default tracing options
You can enable any of the following tracing options.
• Quick Trace method — You can change the default Quick Trace settings to any preset style, or to the most recently used settings.
• Performance — This option determines how source bitmaps between 1 and 5 megapixels in size are handled, and how the quality of
the traced results is affected. The performance of PowerTRACE depends on the size and color depth of the source bitmaps as well as on
the available system memory. High-quality traced results require high-quality source bitmaps, which are often quite large. The larger the
source bitmap, the more resources are required. Bitmaps that are too large need to be downsampled before tracing, which may decrease
the image quality. To trace large bitmaps without sacrificing quality, you can set PowerTRACE to trace images as large as 5 megapixels
(provided RAM is sufficient). To achieve maximum performance, you can set PowerTRACE to prompt you to downsample bitmaps larger
that 1 megapixel.
• Merge colors — You can choose whether to merge colors in a traced result by averaging their values or by replacing the colors to be
merged with the first color you select.
