Enter position command allows to define the position of a reference image interactively. This can be used, for example, to change the positioning of images that do not have georeferencing information. CAD file elements can be used for placing an image position accurately.
To place a reference image interactively:
1. Select the reference image which you want to place interactively.
2. Select Enter position command from the Edit pulldown menu.
3. Define the image origin (south-west corner) of the image by a data click.
4. Define the opposite image corner (north-east corner) of the image by another data click.
This moves the image to the new position. If the defined rectangle is smaller/larger than the original image size, the pixel size of the image is changed.
