Whats new in Touchup 3.0?
The keyhole zoom feature (click on magnifying glass) can be used to calculate distances. Just move the mouse to the start of what you want to measure, hit ‘D’ and move the mouse to the end of what you want to measure. A green line will show the distance you are trying to measure, and the distance is constantly updated as you move the mouse. Perfect for finding out distances on satellite images of the earth, space images (eg: degrees), and Microscope images. Use ‘distScale’ Applet parameter to set a multiplier for pixel distance, and ‘distUnits’ to specify the units for distance. For an image of the earth with 4 meters per pixel resolution, use distScale=’4′ and distUnits=’m’. A third Touchup ‘mode’ has been added, called ‘Basic’.
