Image Import

The image import tab (Figure 65) provides functionality to import an image as a field.

Figure 65 Image Import Tab

Open Image File: Select and load an image

Image Operations:

Invert Grayscale: Invert the grayscale of the image

Flip Vertically: Flip the image up and down

Flip Horizontally: Flip the image left and right

Rotate Image:

Angle (°): Rotate the image

The original image is rotated in the counter-clockwise direction.

Quantize Image:
# Graylevels: Reduce the number of graylevels in the image

Rescale Image: Rescale the image

Lock Aspect Ratio: Enforce equal Factor X and Factor Y

Factor X: X-rescaling factor

Factor Y: Y-rescaling factor

Field Size: Figure 66 shows the field size parameters

field_size

Figure 66 Field Size Parameters

Lock Aspect Ratio: Enforce equal dX and dY

dX (nm): X-spacing between adjacent tip indentations

dY (nm): Y-spacing between adjacent tip indentations

X (µm): X-size of the field

Derived from dX and the imported image X-dimension.

Y (µm): Y-size of the field

Derived from dY and the imported image Y-dimension.

X (px): X-dimension of the field

Derived from the imported image X-dimension.

Y (px): Y-dimension of the field

Derived from the imported image Y-dimension.

Orientation (°): Orientation of the write field relative to the piezo scanner (θ)

Field Depth: Figure 67 shows the conversion between image graylevels and field depths

image_field_depthmap

Figure 67 Image Field Depth Conversion

Exclude White Pixels: No depth assigned to white pixels

When white pixels are excluded, Min (nm) is assigned to the first non-white graylevel. Otherwise, Min (nm) corresponds to white pixels (if present).

Min (nm): Depth assigned to lightest graylevel

Max (nm): Depth assigned to darkest graylevel
