WPF中使用BitmapImage处理图片文件(转)

(1)图片从文件导入

BitmapImage image = new BitmapImage();

image.BeginInit();

image.UriSource = new Uri(filename);

image.EndInit();

(2)图片从Binary导入

//已知Binary binary

MemoryStream ms = new MemoryStream(binary.ToArray());

BitmapImage image = new BitmapImage();

image.BeginInit();

image.StreamSource = ms;

image.EndInit();

(3)保存图片文件

//已知BitmapImage image

JpegBitmapEncoder encoder = new JpegBitmapEncoder();

encoder.Frames.Add(BitmapFrame.Create(image));

FileStream fileStream = new FileStream(imageFileName, FileMode.Create, FileAccess.ReadWrite);

encoder.Save(fileStream);

fileStream.Close();

(4)图片应用到材质

//已知BitmapImage image

ImageBrush imageBrush = new ImageBrush(image);

DiffuseMaterial material = new DiffuseMaterial();

material.Brush = imageBrush;
