I have 30 images that were attached as Raster references , can I rotate in one step and then scale them in one step?
From the Raster Manager dialog box, select all the desired images. (Hint: press and hold on to <Shift> key while selecting first image filename and going down to the last image filename)
Go to Edit menu, and choose "Rotate". Enter the angle value to rotate. Other options include 2 and 3 points rotation.
To Scale, repeat the same procedure as by selecting all the desired images and choose "Scale" from the Edit menu. Enter the value of scale factor.
