Trace Modes

While trace methods determine how to recognize objects in the raster and which objects to recognize, the trace mode determines the final result of tracing – what should be the output.

The trace result can be:

·         Creating vector objects ( Make Vector and Keep Raster),

·         Deleting raster objects when creating vector ones ( Make Vector and Erase Raster),

·         Deleting raster objects ( Erase Raster),

·         Smoothing raster objects ( Smooth Raster).

The trace mode remains active till you choose another mode.

Make Vector

    Ribbon: Raster – Trace – Mode >  Make Vector and Keep Raster

    Menu: Raster – Trace >  Vector (keep raster)

 Command line: MAKEVEKTORANDKEEPRASTER

This mode creates vector objects while saving the original raster – the raster image is vectorized. The Make Vector and Keep Raster trace mode is used by default.

Make vector and erase raster

    Ribbon: Raster – Trace – Mode >  Make Vector and Erase Raster

    Menu: Raster – Trace >  Vector (erase raster)

 Command line: MAKEVEKTORANDERASERASTER

In this mode trace creates approximating vector objects and deletes the traced parts of raster lines. The mode converts raster objects into vector ones.

Erase raster

    Ribbon: Raster – Trace – Mode >  Erase Raster

    Manu: Raster – Trace >  Erase Raster

 Command line: ERASERASTER

In this mode trace removes the traced parts of the raster line and does not create vectors. Intersections or parts of other raster objects under the traced data remain unchanged.

Smooth raster

    Ribbon: Raster – Trace – Mode >  Smooth Raster

    Menu: Raster – Trace >  Smooth Raster

 Command line: SMOOTHRASTER

In this mode trace smooths raster lines.
