Creates an image from a rectangular fragment of another image (with black margins if requested).

Applications

Usually used for creating images of individual objects, e.g. after Template Matching.
Name Type Range Description
Input value
 inImage Image Input image
Input value
 inRectangle Rectangle2D Rectangle defining a rotated subimage
Input value
 inRectangleAlignment CoordinateSystem2D* Adjusts the rectangle to the position of the inspected object
Input value
 inScaleMode CropScaleMode InputScale keeps the input scale unchanged, AlignedScale rescales according to the input alignment scale
Input value
 inInterpolationMethod InterpolationMethod
Input value
 inMargin Real 0.0 - Width of an additional margin for the output image
Input value
 inBorderColor Pixel Color used for locations outside the rectangle
Output value
 outImage Image Output image
Output value
 outAlignedRectangle Rectangle2D Input rectangle after transformation (in the image coordinates)
Output value
 outOutputAlignment CoordinateSystem2D Alignment of the output image

Hints

  • It is usually recommended to use Local Coordinate Systems rather than image cropping.
  • To obtain output images with constant dimensions regardless of inRectangleAlignment set inScaleMode to AlignedScale. The output image size will be equal to inRectangle size optionally modified by inMargin.

Examples
