示例1: Execute
public string Execute(FileItem item, string infile, string dest, ValuePairEnumerator configData)
{
var conf = new EnhanceViewModel(configData);
dest = Path.Combine(Path.GetDirectoryName(dest), Path.GetFileNameWithoutExtension(dest) + ".jpg");

{
if (conf.Normalize)
image.Normalize();
if (conf.AutoGamma)
