When fitting maps, inserting logos and other operations, you may need to align an image (its size, position, rotation) to an existing geometry in an AutoCAD drawing. In special cases you will also need to independently (separately) adjust the image width and height (the aspect ratio of its pixels).
Three different methods of alignment and fitting images are illustrated in the video-tip "Aligning images", available in the section "CAD Video" - see:
The standard AutoCAD command ALIGN, which changes position, size and rotation of an image - but it cannot change its aspect ratio (X/Y pixel size)
The utility CADstudio ImgAdj (see www.cadstudio.cz/download), which can independently modify image width and height; load it with APPLOAD and run the IMGADJ command
The command IRSHEET from AutoCAD Raster Design (included in the version "AutoCAD Design Suite" and in other Autodesk Design Suites), which performs a general transformation, rubbersheeting - adjusting the shape and contents of a raster image to the target outline.
Other options for adjusting position, size and rotation of images are available through the georeferencing functionality included in mapping versions of AutoCAD (Map 3D, Civil 3D).
