Use this dialog box to generate an array of periodic distribution noise.

Dim1—A long integer specifying the size of the first dimension of the output array.

Dim2—A long integer specifying the size of the second dimension of the output array.

Dim3—A long integer specifying the size of the third dimension of the output array. This option is valid only for multi-layered or 24-bit images.

Type—Select the data type of the output array. Choices are BYTE, INT, LONG, FLOAT, DOUBLE.

Create New Image—If this option is selected, the output array is written to a named variable. The output array can be 2D or 3D. Enter the new image variable name in the Output Variable text field.

Overwrite Image—If this option is selected, the currently loaded image variable is overwritten by the processed array.

Add to Image—If this option is selected, the noise array is added to the current image. The current image is replaced by the result.

Multiply by Image—If this option is selected, the noise array is multiplied by the current image. The current image is replaced by the result.

Amplitude—A floating point scalar that indicates the amplitude of the generated noise. (Default: 1.0)

DC Offset—The DC (zero frequency) offset of the noise. A scalar float. (Default 0.0)

Frequency 1—The noise frequency in Hz for the first dimension of the output array.

Frequency 2—The noise frequency in Hz for the second dimension of the output array.

Frequency 3—The noise frequency in Hz for the third dimension of the output array.

Variable Suffix—If the Create New Image option is selected, enter a suffix for the new image variable name. This suffix is added to the original variable name.

OK—Process the image variable and exit the dialog box.

Apply—Process the image, but do not exit the dialog box.

Cancel—Exit the dialog box without taking any action.

Help—Display online Help on the dialog box.
