WMF ➡ CGImageRef, because wv and UniConverter are both GPL/LGPL, and GPL/LGPL is evil (“incompatible with the App Store”).

How?

NSBundle *ownBundle = [NSBundle bundleForClass:[self class]];
NSString *wmfPath = [ownBundle pathForResource:@"Image" ofType:@"wmf"];
NSData *wmfData = [NSData dataWithContentsOfMappedFile:wmfPath];

IRWMFDocument *document = [IRWMFDocument documentWithData:wmfData];
CGImageRef fullResolutionImage = [document newFullResolutionImage];

UIImage *image = [UIImage imageWithCGImage:fullResolutionImage];

if (fullResolutionImage)
    CFRelease(fullResolutionImage);

return image;
