Object ‣ Trace Images to Grease Pencil

The Trace Images to Grease Pencil tool traces a black and white image and generates Grease Pencil strokes. If the image is not black and white, it will be internally converted. For better results, convert the images manually to black and white. Also try to keep the resolution of the image small; high resolutions can produce very dense strokes.

Options

Target Object

The Grease Pencil object name. If left empty, a new Grease Pencil object will be created.

Thickness

The thickness of the generated Grease Pencil strokes.

Resolution

Resolution of the generated Grease Pencil strokes i.e. how many control points the stroke will have. A higher resolution will preserve more detail from the original image.

The object scale applied to the generated Grease Pencil object.

Sample

Recreates the stroke geometry with a predefined length between points. Smaller values will require more points to recreate the stroke, while larger values will result in fewer points needed to recreate the curve. A value of 0 disables stroke sampling.

Color Threshold

Determines what is considered white and what black.

Turn Policy

Determines how to resolve ambiguities during decomposition of an image into paths.

• Black

  Prefers to connect black (foreground) components.

  White

  Prefers to connect white (background) components.

  Left

  Always take a left turn.

  Always take a right turn.

  Minority

  Prefers to connect the color (black or white) that occurs least frequently in the local neighborhood of the current position.

  Majority

  Prefers to connect the color (black or white) that occurs most frequently in the local neighborhood of the current position.

  Random

  Choose pseudo-randomly.

Mode

Determines if the image being traced is an single image or image sequence.
