There are times when it is necessary to adjust how an image is displayed on the Image Tab. There are several ways an image may be adjusted.
Note
Adjusting an image does not edit the actual image file - it only changes how On-Screen Takeoff displays the image - for example, rotating the image 90 degrees only instructs On-Screen Takeoff to rotate the image 90 degrees when displaying it - the actual image is still in the original orientation. If this file is added to a different project or even the same project again, it must be adjusted again. However, adjusting an Overlay creates a TIF copy of that image and all changes are made to that TIF and stored in an "Overlays" subfolder where the original Overlay image file is stored., see Related articles for more information).The Adjust Image Dialog Box
Click the Adjust Images button 
on the Images toolbar or click Image > Adjust Image to bring up the Adjust Images dialog. Some image adjustments are available using shortcut keys, see below for common Image adjustment shortcuts. See Related articles for more information.
Orientation rotates and flips the image.
Visualization adjusts how the image is displayed:
- Enhance - sharpens the visible lines of the image (can make things look less jagged) by default, all images are automatically set to Enhance when added to On-Screen Takeoff. This sharpens the image and makes it easier to view.
- Darken - darkens the visible lines of the image
- Invert - reverses all of the colors (if image was black drawing on a white background, it shows as white drawing on a black background)
- Bitonal - displays image in black and white (not greyscale or color)
Select appropriate options and click OK.
To make these changes to all pages in this project, place a check mark in Apply to All Pages then click OK.
