Color Image Sampling
In the Image Geometry Drawer
The Color Image Sampling tool provides a reduced resolution color image by sampling a user-defined num-
ber of pixels. For example, you can produce an image at one-half resolution by sampling every other pixel.
Impact software uses a 24-bit color system.
Tool Origin The tool’s origin relative to the entire image space
Find Shape List The desired region of the image to fill. If no shape is defined, the entire
image is filled.
Shape List ROI
Type
Each Shape is separate ROI: Each shape is processed as a separate
ROI and the results are combined. This mode is faster than the other
mode if the shapes are far apart, but results are duplicated if the shapes
overlap.
ShapeList is One ROI: The ShapeList is one large rectangular ROI and
the shapes are the enabled pixels within the rectangle. The tool may be
slow if the shapes are far apart. This setting allows shapes to overlap
and form complex shapes without repeating the overlapped pixels and
duplicating results.
NOTE: The resulting image is the same for either setting.
Fill Value The greyscale value to used to fill the area. Zero is black and 100 is
white.
Output Name What it is
Output Image Image with the area filled (may be viewed on the Output Image tab).
Input Name What it is
Input Image Linked Image
Click the plus sign to access greyscale versions of the image that you
can link into other greyscale image processing tools. These images are
similar to the image you get if you use a color filter or color light with a
greyscale camera. See “Color Image Sub-Properties” on page 3-35.
Region of Interest The area of the image to sample. (If zero, the entire image is processed.)
Tool Origin The tool’s origin relative to the entire image space.
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.
Sampling Rotation The output image is rotated by this angle (0, 90, 180, or 270 degrees).
