DrawRectangles_SingleColor


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
Module: FoundationLite

Draws rectangles on an image with a single color.

Syntax

void avs::DrawRectangles_SingleColor
(
	const avl::Image& inImage,
	atl::Conditional<const atl::Array<atl::Conditional<avl::Rectangle2D>>&> inRectangles,
	atl::Optional<const avl::CoordinateSystem2D&> inRectangleAlignment,
	const avl::Pixel& inColor,
	const avl::DrawingStyle& inDrawingStyle,
	const bool inForceRgb,
	avl::Image& outImage
)

Parameters

Name Type Default Description
inImage const Image& Input image
inRectangles Conditional<const Array<Conditional<Rectangle2D>>&> { }
inRectangleAlignment Optional<const CoordinateSystem2D&> NIL
inColor const Pixel&
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

Filter draws rectangles on an input image.

If an rectangle dimensions exceeds image size it will not be drawn or will be drawn partially.

Hints

  • Define inRectangles. This will be the primitives to be drawn.
  • Define inColor. Please note, that on an N-channel image only first N components of the color will be used.
  • 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 DrawRectangles_SingleColor on an empty image.
