我正在尝试通过调整大小将位图图像转换为gif图像。例如,如果位图是3MB,那么我希望gif在转换后出现,例如500x500using System;using System.Collections.Generic;using System.Drawing;using System.IO;using System.Linq;using System.Text;using System.Threading.Tasks;namespace BatchResize{ class Program { static void Main(string[] args) { string[] array1 = Directory.GetFiles(@"C:\temp\tempVideo\MVI_8977.MOV\Lightning 0 Length 25 [48 - 73]"); foreach(string image in array1) { Console.WriteLine("Working on file: " + image); Image img = ResizeImage(image, 500, 500); img.Save(@"C:\temp\newimgs\", System.Drawing.Imaging.ImageFormat.Gif); img.Dispose(); } } //Image Resize Helper Method private static Bitmap ResizeImage(String filename, int maxWidth, int maxHeight) { using (Image originalImage = Image.FromFile(filename)) { //Caluate new Size int newWidth = originalImage.Width; int newHeight = originalImage.Height; double aspectRatio = (double)originalImage.Width / (double)originalImage.Height; if (aspectRatio <= 1 && originalImage.Width > maxWidth) { newWidth = maxWidth; newHeight = (int)Math.Round(newWidth / aspectRatio); } else if (aspectRatio > 1 && originalImage.Height > maxHeight) { newHeight = maxHeight; newWidth = (int)Math.Round(newHeight * aspectRatio); } Bitmap newImage = new Bitmap(newWidth, newHeight); using (Graphics g = Graphics.FromImage(newImage)) } } } }}原始图像是位图,我想调整它们的大小并将其另存为gif。
