示例1: Main
//引入命名空间
using System;
using System.Drawing;
using System.Drawing.Imaging;
class Example_RotateJPEG
{
public static void Main()
{
Bitmap myBitmap;
ImageCodecInfo myImageCodecInfo;
Encoder myEncoder;
EncoderParameter myEncoderParameter;
EncoderParameters myEncoderParameters;
// Create a Bitmap object based on a JPEG file.
myBitmap = new Bitmap("Shapes.jpg");
// Get an ImageCodecInfo object that represents the JPEG codec.
myImageCodecInfo = GetEncoderInfo("image/jpeg");
// Create an Encoder object based on the GUID
// for the Transformation parameter category.
myEncoder = Encoder.Transformation;
// Create an EncoderParameters object.
// An EncoderParameters object has an array of EncoderParameter
// objects. In this case, there is only one
// EncoderParameter object in the array.
myEncoderParameters = new EncoderParameters(1);
// Rotate the image 90 degrees, and save it as a separate JPEG file.
myEncoderParameter = new EncoderParameter(
myEncoder,
(long)EncoderValue.TransformRotate90);
myEncoderParameters.Param[0] = myEncoderParameter;
myBitmap.Save("ShapesR90.jpg", myImageCodecInfo, myEncoderParameters);
