Saves a copy of an image in a specific file format. If the image has multiple frames the command applies to the currently selected frame.
The image is specified by imageRef. If imageRef is not a valid image, error qmed_paramErr is returned.
The target (destination) file is specified by targetPath. The target file may not already exist, but its containing folder path must be valid. If targetPath points to an existing file, the latter will be replaced by the new file. If targetPath is empty, a file selection dialog is presented.
The targetType parameter specifies the target file format. If targetPath is specified and targetType is passed an empty string, targetType defaults to "PICT". If targetPath is not specified, both the target path and type will have to be selected from the file selection dialog. In any other case qmed_ParamErr error will be generated. If the user cancels the dialog, error qmed_userCancelErr is returned.
