Jaehne¶
Presets an image with a pattern designed by Prof. Bernd Jaehne.
Inputs¶
Center (Type: PointDouble)¶
The center of the Jaehne pattern. The default is 512, 512.
Center (Radius: Double)¶
The radius of the Jaehne pattern. The default is 512.
Type (Type: String)¶
The image type. The following types can be chosen: ImageByte, ImageUInt16, ImageUInt32, ImageDouble, ImageRgbByte, ImageRgbUInt16, ImageRgbUInt32, ImageRgbDouble
Dark (Type: String)¶
The value of a dark checkerboard field. This value is converted into the appropriate pixel type, depending on the Type parameter. For monochrome images you should enter one number, for rgb color images you should enter three numbers separated by a space.
Bright (Type: String)¶
The value of a bright checkerboard field. This value is converted into the appropriate pixel type, depending on the Type parameter. For monochrome images you should enter one number, for rgb color images you should enter three numbers separated by a space.
Size (Type: Extent3d)¶
The size of the image that is created. The default value is 1024 x 1024 x 1 pixels.
Region (Type: Region)¶
An optional region that constrains the preset operation to inside the region only. Pixels outside the region are colored with the Background color.
Background (Type: String)¶
The preset value outside of the region. This value is converted into the appropriate pixel type, depending on the Type parameter. For monochrome images you should enter one number, for rgb color images you should enter three numbers separated by a space.
Comments¶
The Jaehne node presets an image with a sinusoidal pattern designed by Prof. Bernd Jaehne. The size of the created image, the radius and center of the pattern, the colors for dark and bright, the region of interest and the background color can all be specified.
Sample¶
Here is an example that shows how to used the Jaehne node.
