问题描述
我需要调整图像,但图像质量不能受此影响。
I need to resize an image, but the image quality cannot be affected by this.
推荐答案
作为rcar说,你不能没有失去一些质量最好的你可以在C#中做的是:
As rcar says, you can't without losing some quality, the best you can do in c# is:
Bitmap newImage = new Bitmap(newWidth, newHeight);
using (Graphics gr = Graphics.FromImage(newImage))
{
gr.SmoothingMode = SmoothingMode.HighQuality;
gr.InterpolationMode = InterpolationMode.HighQualityBicubic;
gr.PixelOffsetMode = PixelOffsetMode.HighQuality;
gr.DrawImage(srcImage, new Rectangle(0, 0, newWidth, newHeight));
}
