Figure D-11: Visualization Browser with Image Properties Displayed

These properties control image object visualizations. For each property, the type of control and the values that can be assigned are listed, along with the property identifier and allowed values for use by the iTools Procedural Interface. For a description of how a particular control is used, refer to Property Controls.

Table D-41: Image Properties
Interface: Property Name	Control Type: Values	API: Property Identifier	API: Allowed Values
Image Palette	User Defined: By selecting Edit Color → Table Edit access the color table to manipulate color values	None	None
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	INTERPOLATE	0 (Nearest neighbor) 1 (Bilinear)
Z value	Number: Z value of plane onto 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`	ZVALUE	Floating point
Grid units	String List: Set grid units type. Choose from: Not applicable Meters Degrees Default = Not applicable	GRID_UNITS	0 (Not applicable--default) 1 (Meters) 2 (Degrees)
Pixel size (x)	Number: Pixel size for x value. Default = `1`	PIXEL_XSIZE	Floating point
Pixel size (y)	Number: Pixel size for y value. Default = `1`	PIXEL_YSIZE	Floating point
Origin (x)	Number: Origin point for x value. Default = `0`	XORIGIN	Floating point
Origin (y)	Number: Origin point for y value. Default = `0`	YORIGIN	Floating point
Unit label	String: The label for image pixel data units.	GEOMETRY_UNIT_LABEL	String
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.	TRANSPARENCY	Integer value from 0 to 100.
