Antenna House Formatter supports Computer Graphics Metafile（CGM）as defined in ISO/IEC 8632. CGM graphics are embedded as vector images with no degradation of image quality. The drawing engine was completely rewritten in AH Formatter V6.4 to support more elements than before. The second page shows a comparison of graphics drawn with AH Formatter V6.4 and AH Formatter V6.3. The CGM drawing function is an optional feature. To use the CGM drawing function, you must purchase “Antenna House Formatter CGM".
