File Display. The top item display the target filename. The Target file is the file you want to perform the Merge/Morph process on.
Load Target Button. Pressing this button allows you to load an SVG map as your Merge/Morph target. You cannot load a target file until you have loaded a Compass Plot file, using the "File -> Open" option from the Menu bar.
Show Compatibility Options. If this check box is enabled, the program will display compatibility options and allow you to change them whenever you load a SVG Target file. Once you have the compatibility settings set the way you want and saved, you can turn off this option so you won't be bothered with it every time you load a file.
Reference Values. This item displays reference information taken from the Source and Target files. If the Source and Target values match, it means that both files are configured identically. Any mismatches indicate the files are identically configured. Any mismatches are highlighted in pink.
