Property
Control Type: Values
Image Palette
User Defined: By selecting Edit Color Table Edit access the color table to manipulate color values
Interpolation
String List: Method used for interpolating the image. Select a method from the list. Choose from these values:
  • Nearest Neighbor: Assign the value of the nearest pixel to the pixel in the output image. Fastest method, but may cause jagged edges.
  •  

  • Bilinear: Create a weighted average based on the nearness and brightness of the closest four pixels, and assign that value to the pixel in the output image.
Default = Nearest Neighbor
Z value
Number: Z value of plane on to which to project the image. Edit the number to change the value.
Note - If the Z value is zero then the image visualization is considered to be 2D. If the Z value is nonzero, then the image visualization is considered to be 3D, and the dataspace associated with this image will be automatically switched to 3D.
Default = 0
Pixel size (x)
Number: Pixel size for x value.
Default = 1
Pixel size (y)
Number: Pixel size for y value.
Default = 1
Origin (x)
Number: Origin point for x value.
Default = 0
Origin (y)
Number: Origin point for y value.
Default = 0
Units
Number: Number of units.
Default = None
Image transparency
Number: Transparency of the image, 0% - 100%. Move the slider to change the value. Default = 0 (no transparency)
Note - The transparency is changed by adding an alpha channel to the image. If your image has an alpha channel then the Transparency property is ignored.
Row Order
String List: Select an order from the list. Choose from these values:
  • Bottom-to-top
  •  

  • Top-to-bottom
Default = Bottom-to-top
