I receive a image/jpeg;base64 string from server.
How can I convert this string to BitmapImage and set like Image.Source ?
string imgStr = "data:image/jpeg;base64,/9j/4AAQSkZJRgABAQEAAQABAAD .... ";
BitmapImage bmp = Base64StringToBitmap(imgStr);
myImage.Source = bmp;
Thanks in advance!
I find solution for my issue:
public static BitmapImage Base64StringToBitmap(string base64String)
{
byte[] byteBuffer = Convert.FromBase64String(base64String);
MemoryStream memoryStream = new MemoryStream(byteBuffer);
memoryStream.Position = 0;
BitmapImage bitmapImage = new BitmapImage();
bitmapImage.SetSource(memoryStream);
memoryStream.Close();
memoryStream = null;
byteBuffer = null;
return bitmapImage;
}

I'm reading data from a blob in MySQL in Base64 String.
I want to convert this to a BitmapImage.
I've tried many ways, but without success.
Here is an example:
public static BitmapImage Base64ToBitmapImage(this string base64String)
{
byte[] binaryData = Convert.FromBase64String(base64String);
BitmapImage img = new BitmapImage();
img.BeginInit();
img.StreamSource = new MemoryStream(binaryData);
img.EndInit();
return img;
}
One example of blob:

In my project, I used this method to convert an array of bytes to BitmapImage:
public static BitmapImage? ConvertToBitmapImage(byte[]? imageData)
{
if (imageData == null || imageData.Length == 0) return null;
var image = new BitmapImage();
using (var mem = new MemoryStream(imageData))
{
mem.Position = 0;
image.BeginInit();
image.CreateOptions = BitmapCreateOptions.PreservePixelFormat;
image.CacheOption = BitmapCacheOption.OnLoad;
image.UriSource = null;
image.StreamSource = mem;
image.EndInit();
}
image.Freeze();
return image;
}
You can use this function by passing an array of bytes to it:
public static BitmapImage? Base64ToBitmapImage(this string base64String)
{
byte[] binaryData = Convert.FromBase64String(base64String);
return ConvertToBitmapImage(binaryData);
}
you can use this functions.
private string ImageToBase64String(string file)
{
Bitmap bitmap = new Bitmap(file);
MemoryStream ms = new MemoryStream();
bitmap.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
byte[] arr = new byte[ms.Length];
ms.Position = 0;
ms.Read(arr, 0, (int)ms.Length);
ms.Close();
string strBase64 = Convert.ToBase64String(arr);
return strBase64;
}
private Bitmap Base64StringToImage(string base64)
{
byte[] arr = Convert.FromBase64String(base64);
MemoryStream ms = new MemoryStream(arr);
Bitmap bitmap = new Bitmap(ms);
return bitmap;
}
The code above works fine. The cause of the problem its on MySQL return.
The value from a blob column returns returns as a byte on C# MySQL Lybrary.
And I was converting it to a Base64 String and recoverting to a byte.
I excluded this confusion in my code and problem fixed.
Like in the title. How to convert BitmapeImage to byte in metro style app. Ther is no System.drawing lib.
I need it to use in LuminanaceSource() which need source in byte[].
Have some example, but i dont know how to use it.
BitmapImage bmpImage = new BitmapImage(new Uri(file.Path));
var encoderId = Windows.Graphics.Imaging.BitmapEncoder.JpegEncoderId;
Thanks
these two methods should convert Bitmap image to byte[] and viceversa.
public BitmapImage ImageFromBuffer(Byte[] bytes)
{
MemoryStream stream = new MemoryStream(bytes);
BitmapImage image = new BitmapImage();
image.BeginInit();
image.StreamSource = stream;
image.EndInit();
return image;
}
public Byte[] BufferFromImage(BitmapImage imageSource)
{
Stream stream = imageSource.StreamSource;
Byte[] buffer = null;
if (stream != null && stream.Length > 0)
{
using (BinaryReader br = new BinaryReader(stream))
{
buffer = br.ReadBytes((Int32)stream.Length);
}
}
return buffer;
}
I am trying to extract a BitmapImage from a JPG. This is the code I have:
FileStream fIn = new FileStream(sourceFileName, FileMode.Open); // source JPG
Bitmap dImg = new Bitmap(fIn);
MemoryStream ms = new MemoryStream();
dImg.Save(ms, ImageFormat.Jpeg);
image = new BitmapImage();
image.BeginInit();
image.StreamSource = new MemoryStream(ms.ToArray());
image.EndInit();
ms.Close();
image comes back with a 0 × 0 image, which of course means it didn't work. How do I do this?
Try this:
public void Load(string fileName)
{
using(Stream BitmapStream = System.IO.File.Open(fileName,System.IO.FileMode.Open ))
{
Image img = Image.FromStream(BitmapStream);
mBitmap=new Bitmap(img);
//...do whatever
}
}
Or you can just do this (source):
Bitmap myBmp = Bitmap.FromFile("path here");
I have BitmapImage in C#. I need to do operations on image. For example grayscaling, adding text on image, etc.
I have found function in stackoverflow for grayscaling which accepts Bitmap and returns Bitmap.
So I need to convert BitmapImage to Bitmap, do operation and convert back.
How can I do this? Is this best way?
There is no need to use foreign libraries.
Convert a BitmapImage to Bitmap:
private Bitmap BitmapImage2Bitmap(BitmapImage bitmapImage)
{
// BitmapImage bitmapImage = new BitmapImage(new Uri("../Images/test.png", UriKind.Relative));
using(MemoryStream outStream = new MemoryStream())
{
BitmapEncoder enc = new BmpBitmapEncoder();
enc.Frames.Add(BitmapFrame.Create(bitmapImage));
enc.Save(outStream);
System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(outStream);
return new Bitmap(bitmap);
}
}
To convert the Bitmap back to a BitmapImage:
[System.Runtime.InteropServices.DllImport("gdi32.dll")]
public static extern bool DeleteObject(IntPtr hObject);
private BitmapImage Bitmap2BitmapImage(Bitmap bitmap)
{
IntPtr hBitmap = bitmap.GetHbitmap();
BitmapImage retval;
try
{
retval = (BitmapImage)Imaging.CreateBitmapSourceFromHBitmap(
hBitmap,
IntPtr.Zero,
Int32Rect.Empty,
BitmapSizeOptions.FromEmptyOptions());
}
finally
{
DeleteObject(hBitmap);
}
return retval;
}
Here's an extension method for converting a Bitmap to BitmapImage.
public static BitmapImage ToBitmapImage(this Bitmap bitmap)
{
using (var memory = new MemoryStream())
{
bitmap.Save(memory, ImageFormat.Png);
memory.Position = 0;
var bitmapImage = new BitmapImage();
bitmapImage.BeginInit();
bitmapImage.StreamSource = memory;
bitmapImage.CacheOption = BitmapCacheOption.OnLoad;
bitmapImage.EndInit();
bitmapImage.Freeze();
return bitmapImage;
}
}
If you just need to go from BitmapImage to Bitmap it's quite easy,
private Bitmap BitmapImage2Bitmap(BitmapImage bitmapImage)
{
return new Bitmap(bitmapImage.StreamSource);
}
using System.Windows.Interop;
...
private BitmapImage Bitmap2BitmapImage(Bitmap bitmap)
{
BitmapSource i = Imaging.CreateBitmapSourceFromHBitmap(
bitmap.GetHbitmap(),
IntPtr.Zero,
Int32Rect.Empty,
BitmapSizeOptions.FromEmptyOptions());
return (BitmapImage)i;
}
I've just been trying to use the above in my code and I believe that there is a problem with the Bitmap2BitmapImage function (and possibly the other one as well).
using (MemoryStream ms = new MemoryStream())
Does the above line result in the stream being disposed of? Which means that the returned BitmapImage loses its content.
As I'm a WPF newbie I'm not sure that this is the correct technical explanation, but the code didn't work in my application until I removed the using directive.
Here the async version.
public static Task<BitmapSource> ToBitmapSourceAsync(this Bitmap bitmap)
{
return Task.Run(() =>
{
using (System.IO.MemoryStream memory = new System.IO.MemoryStream())

Thanks Guillermo Hernandez, I created a variation of your code that works. I added the namespaces in this code for reference.
System.Reflection.Assembly theAsm = Assembly.LoadFrom("My.dll");
// Get a stream to the embedded resource
System.IO.Stream stream = theAsm.GetManifestResourceStream(#"picture.png");
// Here is the most important part:
System.Windows.Media.Imaging.BitmapImage bmi = new BitmapImage();
bmi.BeginInit();
bmi.StreamSource = stream;
bmi.EndInit();
This converts from System.Drawing.Bitmap to BitmapImage:
MemoryStream ms = new MemoryStream();
YOURBITMAP.Save(ms, System.Drawing.Imaging.ImageFormat.Bmp);
BitmapImage image = new BitmapImage();
image.BeginInit();
ms.Seek(0, SeekOrigin.Begin);
image.StreamSource = ms;
image.EndInit();
I'm trying to Convert a Bitmap (SystemIcons.Question) to a BitmapImage so I can use it in a WPF Image control.
I have the following method to convert it to a BitmapSource, but it returns an InteropBitmapImage, now the problem is how to convert it to a BitmapImage. A direct cast does not seem to work.
Does anybody know how to do it?
CODE:
public BitmapSource ConvertToBitmapSource()
{
int width = SystemIcons.Question.Width;
int height = SystemIcons.Question.Height;
object a = System.Windows.Interop.Imaging.CreateBitmapSourceFromHBitmap(SystemIcons.Question.ToBitmap().GetHbitmap(), IntPtr.Zero, System.Windows.Int32Rect.Empty, BitmapSizeOptions.FromWidthAndHeight(width, height));
return (BitmapSource)a;
}
property to return BitmapImage: (Bound to my Image Control)
public BitmapImage QuestionIcon
{
get
{
return (BitmapImage)ConvertToBitmapSource();
}
}
InteropBitmapImage inherits from ImageSource, so you can use it directly in an Image control. You don't need it to be a BitmapImage.
You should be able to use:
public BitmapImage QuestionIcon
{
get
{
using (MemoryStream ms = new MemoryStream())
{
System.Drawing.Bitmap dImg = SystemIcons.ToBitmap();
dImg.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
ms.Position = 0;
System.Windows.Media.Imaging.BitmapImage bImg = new System.Windows.Media.Imaging.BitmapImage();
bImg.BeginInit();
bImg.StreamSource = new MemoryStream(ms.ToArray());
bImg.EndInit();
return bImg;
}
}
}
public System.Windows.Media.Imaging.BitmapImage QuestionIcon
{
get
{
using (MemoryStream ms = new MemoryStream())
{
System.Drawing.Bitmap dImg = SystemIcons.ToBitmap();
dImg.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg);
ms.Position = 0;
var bImg = new System.Windows.Media.Imaging.BitmapImage();
bImg.BeginInit();
bImg.StreamSource = ms;
bImg.EndInit();
return bImg;
}
}
}
