Image modes affect only the display of the loaded source. Measurement and helper geometry remain unchanged.
Opacity
Source opacity is available in both Basic and PRO. It is particularly useful when comparing the drawing with overlay geometry.
Grayscale
The PRO grayscale mode removes color information and can improve the readability of some scanned documents.
High contrast
The PRO high-contrast mode emphasizes differences between the drawing and the background. It is particularly useful for faded or poor-quality scans.
