In-place Processing
This function supports in-place data processing - you can pass the same reference to inImage and outImage

Description
The operation draws an array of paths on the inImage using common drawing parameters for all of them. Paths may exceed the image dimensions - those will be drawn partially or not at all, but the filter execution will succeed.
Hints
- Define inPaths. This will be the primitives to be drawn.
- Leave inPalette and inColorIds not set to have all the primitives drawn with random colors. Set a custom palette 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.
- Set inDrawingStyle to control quality, opacity, thickness, filling, point shapes and sizes.
Examples

Example usage of the DrawPaths_MultiColor on an empty image.
Errors
List of possible exceptions:
Error type | Description |
---|---|
DomainError | Empty inPalette while inPaths has objects to draw in DrawPaths_MultiColor. |
DomainError | No palette defined with inPalette for specified inColorIds in DrawPaths_MultiColor. |
DomainError | The sizes inPaths and inColorIds do not match in DrawPaths_MultiColor. |
