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