Image Generator

StreamableKNIME Image Types and Nodes version 1.8.0.201907250605 by University of Konstanz

Generates (random) images according to the specified options.

Options

How many images shall be created?
Number of images which are created.
Img size
Select the sizes of the image in the various dimensions. The first value specifies the minimum, the second the maximum size. E.g. the entry 1,10 will result in images from (including) size 1 to 10 in the selected dimension. Setting both values to zero excludes a dimension.
Random size in bounds
If selected, random images within the defined dimensionality will be generated. For example, if you select X and Y to be 100 each, then the resulting images may be of size [1;100] for X and Y respectively.
Pixel Type
Select the pixel type of the resulting images. If you select random, each generated image may have another PixelType. Please keep in mind, that the larger your PixelType (e.g. IntType needs more memory than ByteType) the more memory is uses.
Factory type
Select the factory type of the resulting images. If you select random, each generated image may have another factory.
Image content
Select a constant value as the value of each pixel or select the pixels to be set randomly according to their value range. (e.g. ByteType is -128 up to 127).

Views

Image Viewer
Another, possibly interactive, view on table cells. Displays the selected cells with their associated viewer if it exists. Available views are:
- Combined View
-- A viewer shown when the user selects an interval of rows and columns in the viewer. This viewer combines all images and labelings in the selected interval to one image by rendering them next to each other. Alternatively, the images and labelings can be layed over each other.
- XML
-- XML tree
- Histogram Viewer
-- This viewer shows the histogram of the currently selected image.
- Labeling View
-- View on a labeling/segmentation
- Image Viewer
-- This viewer renders the selected image-cell.
- BigDataViewer
-- A viewer shown when the user selects an interval of rows and columns in the viewer. This viewer combines all images and labelings in the selected interval to one image by rendering them next to each other. Alternatively, the images and labelings can be layed over each other.
- Missing Value Viewer
-- An empty viewer that is shown when the input cell has no value to display.
