Description
The operation draws an array of shape regions on the inImage using common drawing parameters for all of them.
Regions may exceed the image dimensions - those will be drawn partially or not at all, but the filter execution will succeed.
Hints
- Connect an image source to the inImage input. Drawing will be done on this image.
- If you want to draw on an empty background, use EmptyImage filter before.
- Define inRois This will be the primitives to be drawn.
- Leave the inPalette and inColorIds not set to have all the primitives drawn with random colors. Set a custom array of colors here to decide explicitly how each of the primitives should be drawn using inColorIds.
- Set inForceRgb to True, if you want to get a 3-channel output regardless of what is on the input.
Examples
Description of usage of this filter can be found in examples and tutorial: Blister Inspection (NET GmbH).

Errors
This filter can throw an exception to report error. Read how to deal with errors in Error Handling.
List of possible exceptions:
Error type | Description |
---|---|
DomainError | Empty inPalette while inRois has objects to draw in DrawShapeRegions_MultiColor. |
DomainError | No palette defined with inPalette for specified inColorIds in DrawShapeRegions_MultiColor. |
DomainError | The sizes inRois and inColorIds do not match in DrawShapeRegions_MultiColor. |
