Trace Images to Grease Pencil
Reference
- Mode
Object Mode
- Menu
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.
Usage
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.
- Left
Always take a left turn.
- Right
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.
