DrawPaths_MultiColor

This is Filter Equivalent. This function may be present in generated code, but should not be used in hand-written code.

Header:	AVL.h
Namespace:	avs

Draws paths on an image with multiple colors.

Syntax

void avs::DrawPaths_MultiColor
(
	const avl::Image& inImage,
	atl::Conditional< const atl::Array<atl::Conditional<avl::Path>>&> inPaths,
	atl::Optional<const avl::CoordinateSystem2D&> inPathAlignment,
	atl::Optional<const atl::Array<atl::Conditional<avl::Hash>>&> inColorIds,
	atl::Optional<const atl::Array<avl::Pixel>&> inPalette,
	const avl::DrawingStyle& inDrawingStyle,
	const bool inForceRgb,
	avl::Image& outImage
)

Parameters

Name	Type	Default	Description
inImage	const Image&		Input image
inPaths	Conditional< const Array<Conditional<Path>>&>	{ }
inPathAlignment	Optional<const CoordinateSystem2D&>	NIL
inColorIds	Optional<const Array<Conditional<Hash>>&>	NIL
inPalette	Optional<const Array<Pixel>&>	{ Pixel ( X: 200.0f Y: 0.0f Z: 0.0f W: 0.0f ), Pixel ( X: 0.0f Y: 200.0f Z: 0.0f W: 0.0f ) }
inDrawingStyle	const DrawingStyle&	DrawingStyle ( DrawingMode: HighQuality Opacity: 1.0f Thickness: 1.0f Filled: False PointShape: Nil PointSize: 1.0f )
inForceRgb	const bool	True	Filter will convert monochromatic image to RGB if needed
outImage	Image&		Output image

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.
