将SVG图像转换为Base64 [英] Convert SVG image to Base64

问题描述

你好

我正在尝试将图像转换为Base64字符串并将其显示在我的WPF应用程序中

i am trying to Convert Image to Base64 string and display it in my WPF Application

转换代码

  Microsoft.Win32.OpenFileDialog dlg = new Microsoft.Win32.OpenFileDialog(); 

            Nullable<bool> result = dlg.ShowDialog();

            if (result == true)
            {
                byte[] imageArray = System.IO.File.ReadAllBytes(dlg.FileName);
                string base64ImageRepresentation = Convert.ToBase64String(imageArray);
              
                textBox.Text = base64ImageRepresentation;
               
               
            }

将base64显示为图像的代码

Code to display base64 as Image 

 byte[] binaryData = Convert.FromBase64String(textBox.Text);

            BitmapImage bi = new BitmapImage();
            bi.BeginInit();
            bi.StreamSource = new MemoryStream(binaryData);
            bi.EndInit();
 
            imageSection.Source = bi;

它适用于所有图像格式(Gif，Jpg，Png)的SVG.

It work well for all Image Format(Gif, Jpg, Png) exept SVG.

嗨CPGtech，

Hi   CPGtech,

>>如何为SVG格式自定义我的代码?

据我所知，SVG是一种用于描述XML中的二维图形的语言. SVG允许使用三种类型的图形对象:矢量图形形状(例如，由直线和曲线组成的路径)，图像和文本.

As far as I know, SVG is a language for describing two-dimensional graphics in XML. SVG allows for three types of graphic objects: vector graphic shapes (e.g., paths consisting of straight lines and curves), images and text.

因此，也许您应该先将SVG转换为Image，然后再将图像转换为Base64.

So, May be you should convert SVG to Image firstly, then convert the image to Base64.

您可以尝试使用某些第三方扩展.
