合并两个图片成一个图片的代码

合并两个图片成一个图片的代码 代码实现： enum ImageMergeOrientation { Horizontal, Vertical } private void CombineImages(FileInfo[] files, string toPath, ImageMergeOrientation mergeType = ImageMergeOrientation.Vertical) { //change the location to store the final image. // URL：http://www.bianceng.cn/Programming/csharp/201410/45751.htm var finalImage = toPath; var imgs = files.Select(f => Image.FromFile(f.FullName));

var finalWidth = mergeType == ImageMergeOrientation.Horizontal ? imgs.Sum(img => img.Width) : imgs.Max(img => img.Width); var finalHeight = mergeType == ImageMergeOrientation.Vertical ? imgs.Sum(img => img.Height) : imgs.Max(img => img.Height); var finalImg = new Bitmap(finalWidth, finalHeight); Graphics g = Graphics.FromImage(finalImg); g.Clear(SystemColors.AppWorkspace); var width = finalWidth; var height = finalHeight; var nIndex = 0; foreach (FileInfo file in files) { Image img = Image.FromFile(file.FullName); if (nIndex == 0) { g.DrawImage(img, new Point(0, 0)); nIndex++; width = img.Width; height = img.Height; } else { switch (mergeType) { case ImageMergeOrientation.Horizontal: g.DrawImage(img, new Point(width, 0)); width += img.Width; break; case ImageMergeOrientation.Vertical: g.DrawImage(img, new Point(0, height)); height += img.Height; break; default: throw new ArgumentOutOfRangeException("mergeType"); } } img.Dispose(); } g.Dispose(); finalImg.Save(finalImage, System.Drawing.Imaging.ImageFormat.Tiff); finalImg.Dispose(); }

代码说明： 根据参数进行横向或纵向合并图片 如果为横向，图片高度为最高的那张；如果纵向则宽度为最宽的那张 UT 代码： [TestMethod] public void Combine_Multiple_SampleImages_IntoOne() { const string folderPath = “C:\Users\Public\Pictures\Sample Pictures”; var images = new DirectoryInfo(folderPath).GetFiles(“*.jpg”, SearchOption.TopDirectoryOnly);

CombineImages(images, "C:/FinalImage_H.tiff"); CombineImages(images, "C:/FinalImage_V.tiff", ImageMergeOrientation.Vertical); }

C# code 合并图片的功能 string path = Server.MapPath(“~/temp/”); string imgFilePath1 = path + “123456ASDFG.JPG”; string imgFilePath2 = path + “aaaaaaaaaaa.JPG”; if (!File.Exists(imgFilePath1)) File.Create(imgFilePath1); System.Drawing.Image img1 = System.Drawing.Image.FromFile(imgFilePath1); System.Drawing.Image img2 = System.Drawing.Image.FromFile(imgFilePath2); Bitmap newImg = new Bitmap((img1.Width > img2.Width) ? img1.Width : img2.Width, img1.Height + img2.Height); Graphics g = Graphics.FromImage(newImg); g.Clear(Color.Blue); g.DrawImageUnscaled(img1, 0, 0); g.DrawImageUnscaled(img2,0, img1.Height);

img1.Dispose(); newImg.Save(imgFilePath1); g.Dispose();
