Undo, redo, and repeat trace
Experiment freely with different tracing options to achieve the desired result. Undo or redo changes as needed, or revert to the first traced result at any time.
You can trace a bitmap using the same settings as the most recent trace. This is useful when processing a series of similar images that require consistent results. The last-used settings include the selected trace type and profile, resample mode, and color sorting option, as well as the values for node density and curvature, and the states of options such as Remove JPEG artifacts, Delete original image, Merge adjacent shapes, Remove overlap, and Group objects.
You can open the PowerTRACE dialog box with the settings from the previous tracing operation. This lets you continue where you left off, review or modify the settings, and apply the trace only when you are ready.
