EROIBW8 Class

The EROIBW8 class is used to represent rectangular regions of interest inside BW8 gray-level images. See ROIs.

Base Class:EBaseROI

Derived Class(es):EImageBW8

Namespace: Euresys::Open_eVision

License(s): Any

Constructors

Constructs the EROIBW8 object In a general content, the term object should be understood with the meaning of a class instance. In EasyObject, an object is a maximally-sized area of adjacent connected pixels belonging to the layer foreground..

Properties

See GetFirstSubROI in the derived classes

This method returns the ROI that is the next sibling of this ROI.

Returns the hierarchical parent of this object.

Returns the top parent of this object.

Methods

Returns the next ROI in the list starting at startROI or null if there is no next ROI.

Allows reading a single pixel value in the ROI or image.

Assignment operator.

Allows writing a single pixel value in the ROI or image.

Module: open_evision

License(s): Any

Constructors

Constructs the EROIBW8 object.

Properties

See GetFirstSubROI in the derived classes

This method returns the ROI that is the next sibling of this ROI.

Returns the hierarchical parent of this object.

Returns a pixel view of the ROI, allowing usage of the pixels defined in that ROI with the buffer protocol in Python.

Example usage in Python:

```python import open_evision import numpy

image = EImageBW8(100, 100) np_view = numpy.asarray(image.PixelView) ```

Returns the top parent of this object.

Methods

Constructs the EROIBW8 object.

Returns the next ROI in the list starting at startROI or null if there is no next ROI.

Allows reading a single pixel value in the ROI or image.

Allows writing a single pixel value in the ROI or image.
