Image Sampling
In the Image Geometry Drawer
The Image Sampling tool provides a reduced resolution image by sampling a user-defined number of pixels.
For example, you can produce an image at one-half resolution by sampling every other pixel.
Image Stitching with Origins
In the Image Geometry Drawer
The Image Stitching with Origins tool provides the ability to combine (stitch) several smaller images into
one large image using features in the images as reference points for the overlap. For example, you can take
several images of sections of a large connector, then stitch them together to inspect the whole connector
image.
Input Name What it is
Input Image Linked Image
Tool Origin The tool’s origin relative to the entire image space.
Region of Interest The area of the image to sample. (if zero, the entire image is processed)
Sampling Resolu-
tion
How many pixels to sample; 1 is every pixel, 2 is every other pixel, etc.
This applies to x and y dimensions.
Anti Alias Flag If True, the image is filtered before it is sampled.
Sampling Rotation The output image is rotated by this angle (0, 90, 180, or 270 degrees).
Mirror None: The Output Image is not changed.
Horizontal: The Output Image is flipped horizontally.
Vertical: The Output Image is flipped vertically.
Any mirroring takes place after windowing and sampling operations.
Output Name What it is
Output Image Reduced resolution image within ROI (may be viewed on the Output
Image tab).
Input Name What it is
Image 1 The first image to be stitched
Overlap Feature
Location in Image 1
The origin of the feature to be used to indicate the overlap between
image 1 and image 2
Image 2 The second image to be stitched
Overlap Feature
Location in Image 2
The origin of the feature to be used to indicate the overlap between
image 2 and image 1
