Cristallight (http://www.cristallight.com/) has announced WMF Converter Pro 3.1.0, an update to its professional level image tool for Mac OS X 10.5 and higher. It costs US$19.95, which includes the lifetime license with free upgrades, and free tech support.
WMF Converter Pro allows you to render and convert single or multiple WMF files, preview them, change colors in vector based WMF files, and save either all of them or selected ones as Mac native images in one of 10 file formats, including both vector and raster formats. The image resolution setting can also be used when saving in raster image formats.
You can open one or more WMF file(s), or just drag files or folders with WMF files to the WMF Converter window and the images will appear in the Image Preview Area. Set the Export format and resolution, if necessary, and click one of the export buttons on the toolbar. Other features include the ability to replace color functionality, customizable image preview size, WMF file information display, batch convert WMF files processing, multiple export buttons, and destination folder control.
