You can use the Bias tool to correct distortions in the image's aspect ratio. The X and Y directions are relative to the image itself, not its position in the drawing. In each case, you can select two points (or enter a distance) to define the calibration distance, then select two corresponding points (or enter a new distance) to specify the desired distance.

The Bias command can only operate on a single image at a time.

PROCEDURE:

Select the image you want to correct by clicking its image frame, then press Enter.
Specify a point in the drawing to use as the base point, or press Enter to use the origin as the base point.
Enter a calibration distance for the X direction by selecting two points to represent the distance, or enter the distance manually.
Enter the desired distance for the X direction using one of the two methods, or press Enter to leave the X direction unchanged.
Enter a calibration distance for the Y direction by selecting two points to represent the distance, or enter the distance manually.
Enter the desired distance for the Y direction using one of the two methods, or press Enter to leave the Y direction unchanged.

Note: When an image is modified using any tool from the Raster Draw module, changes made to the original image file may affect any other drawings that reference the same image. For more information, refer to Effect of Editing an Image.
