DrawCircles_TwoColors
This is Filter Equivalent. This function may be present in generated code, but should not be used in hand-written code.
Draws circles on an image with two colors, depending on the status of each circle (usually: green or red for pass/fail status).
Syntax
void avs::DrawCircles_TwoColors
(
const avl::Image& inImage,
const atl::Conditional<atl::Array<atl::Conditional<avl::Circle2D> > >& inCircles,
atl::Optional<const avl::CoordinateSystem2D&> inCircleAlignment,
const avl::Pixel& inColorIfTrue,
const avl::Pixel& inColorIfFalse,
const atl::Conditional<atl::Array<atl::Conditional<bool> > >& inConditions,
const avl::DrawingStyle& inDrawingStyle,
const bool inForceRgb,
avl::Image& outImage
)

Description
The operation draws an array of circles on the inImage using common drawing parameters for all of them.
Circles may exceed the image dimensions - those will be drawn partially or not at all, but the filter execution will succeed.
Hints
- Define inCircles. This will be the primitives to be drawn.
- Define inConditions with the boolean values indicating the class (usually: OK/NOK) for each input primitive.
- Set the inColorIfTrue and inColorIfFalse inputs to define the two colors used for drawing.
- 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.
