文件大小调整并将其保存到目标文件夹 [英] file resizing and saving it to a target folder

问题描述

我必须调整现有图像的大小并选择适当的宽度和高度。

现在这是代码我有这样的代码



图像已调整大小= ResizeImageForFull（原始，新大小（768,1024））;



//将图像保存到内存流

MemoryStream memStream = new MemoryStream（）;

resized.Save（memStream，System.Drawing.Imaging.ImageFormat.Jpeg）





获取修改后的图像后将其保存到内存流中。任何人都可以帮我把它放到目标文件夹中保存为jpeg图像。

I have to re size an existing image and with proper width and height.
for now this is the code I have the code like this

Image resized = ResizeImageForFull(original, new Size(768, 1024));

//save the image to memory stream
MemoryStream memStream = new MemoryStream();
resized.Save(memStream, System.Drawing.Imaging.ImageFormat.Jpeg)


after getting the modified image it is saved to the memory stream. can any one help me to put that into a target folder to save it as a jpeg image.

public static Image ResizeImageForFull(Image image, Size size, bool preserveAspectRatio = true)
        {
            int newWidth=0;
            int newHeight=0;

            if (preserveAspectRatio)
            {
                newWidth = size.Width;
                newHeight = size.Height;
            }

            Image newImage = new Bitmap(newWidth, newHeight);
            using (Graphics graphicsHandle = Graphics.FromImage(newImage))
            {
                graphicsHandle.InterpolationMode = InterpolationMode.HighQualityBicubic;
                graphicsHandle.DrawImage(image, 0, 0, newWidth, newHeight);
            }

            return newImage;
        }

推荐答案

Hello Lima3，



你'使用此方法保存图像：

Hello Lima3,

You're using this method to save the image:

public void Save(
    Stream stream,
    ImageFormat format
)

使用FileStream代替使用MemoryStream。

Instead of using a MemoryStream, use a FileStream.
