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500x500
using 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。
