Table D-41: Image Properties

Table D-41: Image Properties
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
