Applications

Apart from drawing can also be used to "clear" a part of an image.

Description

The operation draws an array of regions on the inImage using common drawing parameters for all of them. Regions may exceed the image dimensions - those will be drawn partially or not at all, but the filter execution will succeed.

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 filter before.
Define inRegions. 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.

Examples
