Images-Transform
Geometric transformation is widely used in geometric distortion adjustment and thus considered an important pre-process. Besides, some transfer can also be used in image creation, such as Flip and Shear. Origin supports many geometric transformations including:
It is useful when dealing with large size image and only a small region is interested.
It is commonly used to cut off a single or multiple edges from an image with intensity change at the edge(s).
It can be used to create a "mirror image".
It can be used when comparing a pair of images with an offset between each other.
It can be used in creating a 3D projection in a 2D image.
In most cases, you can choose to crop an interested part of an image or trim out the space outside the interested part. However, you may find Trim extremely useful when working on an image with a transparent background and gradually faded out edges. In this case, it is tricky to identify the exact edge to crop. However, Trim can detect it automatically, see a simple example here.
Resize Image changes the image size by the specified width and height. In other words, Resize Image resizes width and height independently and won't keep the original aspect ratio, so it may lead to distortion. Image Scale on the other hand, keeps the aspect ratio and be "cut off" if the rescaled image is expanded outside the layer.
Besides, for image color, Origin also allows you to invert colors which is popular in film processing.
