This is Filter Equivalent. This function may be present in generated code, but should not be used in hand-written code.
Draws boxes on an image with multiple colors.
Syntax
void avs::DrawBoxes_Palette ( const avl::Image& inImage, const atl::Conditional<atl::Array<atl::Conditional<avl::Box> > >& inBoxes, const atl::Optional<atl::Array<avl::Pixel> >& inColors, const float inOpacity, const bool inForceRgb, avl::Image& outImage )
Parameters
Name | Type | Range | Default | Description | |
---|---|---|---|---|---|
inImage | const Image& | Input image | |||
inBoxes | const Conditional<Array<Conditional<Box> > >& | { } | |||
inColors | const Optional<Array<Pixel> >& | NIL | |||
inOpacity | const float | 0.0 - 1.0 | 1.0f | ||
inForceRgb | const bool | True | Filter will convert monochromatic image to RGB if needed | ||
outImage | Image& | Output image |
Description
The operation draws an array of boxes on the inImage using common drawing parameters for all of them. Boxes may exceed the image dimensions - those will be drawn partially or not at all, but the filter execution will succeed. Note that drawing is conducted in a pixel-precise way as the Box type is pixel-precise.
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 function before.
- Define inBoxes. This will be the primitives to be drawn.
- Leave the inColors input 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.
- Set inForceRgb to True, if you want to get a 3-channel output regardless of what is on the input.
