Trace Images to Grease Pencil

Reference

Mode: Object Mode
Menu: Object ‣ Convert ‣ 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.

Penggunaan

Add an Image Empty to the scene.
Run Trace Images to Grease Pencil.

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.

Scale

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

Determine the Luminance threshold above which strokes are generated.

Turn Policy

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

Black: Prioritizes to connect black (foreground) components.
White: Prioritizes to connect white (background) components.
Kiri: Always take a left turn.
Kanan: Always take a right turn.
Minority: Prioritizes to connect the color (black or white) that occurs least frequently in the local neighborhood of the current position.
Majority: Prioritizes 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 a single image or image sequence.

Single: The image empty is a single image or the current frame of an image sequence.
Sequence: The image empty is an Image Sequence.

Start at Current Frame

When enabled, start the tracing process at the current image frame.

Trace Frame

Used to trace only one frame of the image sequence, set to zero to trace all.
