How can i clear the memory after converting BitmapImage to Byte

I have two functions: one to convert from image to byte and other to convert from byte to bitmapImage.
So, when I open the window with that images, I convert from byte to bitmapImage and it works great, but when I close and open it again it just keeps on memory and if I continue to do that time and time again it just throws an exception Out Of Memory exception
Image to byte->
private byte[] ConvertImageToBinary(Image img)
{
using (MemoryStream ss = new MemoryStream())
{
img.Save(ss, System.Drawing.Imaging.ImageFormat.Jpeg);
var s = ss.ToArray();
var jpegQuality = 50;
Image image;
using (var inputStream = new MemoryStream(s))
{
image = Image.FromStream(inputStream);
var jpegEncoder = System.Drawing.Imaging.ImageCodecInfo.GetImageDecoders()
.First(c => c.FormatID == System.Drawing.Imaging.ImageFormat.Jpeg.Guid);
var encoderParameters = new System.Drawing.Imaging.EncoderParameters(1);
encoderParameters.Param[0] = new System.Drawing.Imaging.EncoderParameter(System.Drawing.Imaging.Encoder.Quality, jpegQuality);
Byte[] outputBytes;
using (var outputStream = new MemoryStream())
{
image.Save(outputStream, jpegEncoder, encoderParameters);
return outputBytes = outputStream.ToArray();
}
}
}
}
Byte to bitmap ->
public BitmapImage ConvertBinaryToImage(byte[] array)
{
var image = new BitmapImage();
using (var ms = new MemoryStream(array))
{
image.BeginInit();
image.CacheOption = BitmapCacheOption.OnLoad; // here
image.StreamSource = ms;
image.EndInit();
image.Freeze();
}
return image;
}
When I open the WindowDragAndDrop it loads all the images
But when I close it it still uses the same amount of memory

Image is indeed disposable (https://learn.microsoft.com/en-us/dotnet/api/system.drawing.image?view=netframework-4.8), so you also need:
using (var image = Image.FromStream(inputStream)){
}
Around everywhere you use Image objects.

Bitmap from Memstream of an SVG gives invalid parameter exception

The last line of the following code gives the error "Parameter is not valid", when the original image is an SVG:
var imageBytes = Convert.FromBase64String(imageBase64String);
var memStream = new MemoryStream(imageBytes);
//memStream.Seek(0, SeekOrigin.Begin);
var imageObject = new Bitmap(memStream);
Help please. Thanks.
EDIT: The image for example I am using is the image of the first formula in the following page right under the Theoremsection:
https://en.wikipedia.org/wiki/Green%27s_theorem

Can you try with 'using' for memorystream to handle garbage collection by itself?
var imageBytes = Convert.FromBase64String(imageBase64String);
Bitmap m = ByteToBitmap(imageBytes);
public static Bitmap ByteToBitmap(byte[] imageByte)
{
using (MemoryStream mStream = new MemoryStream())
{
mStream.Write(imageByte, 0, imageByte.Length); // this will stream dataand handle image length by itself
mStream.Seek(0, SeekOrigin.Begin);
Bitmap bm = new Bitmap(mStream);
return bm;
}
}
For SVG,
public static Bitmap ByteToBitmap(byte[] imageByte)
{
using (MemoryStream mStream = new MemoryStream(imageByte))
{
var s= SvgDocument.Open(mStream);
var bm= svgDocument.Draw();
return bm;
}
}

Convert BitmapImage to byte in metro app

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;
}

Error" Parameter is not valid " while converting Bytes into Image

I am converting bytes into an image but I get an error
Parameter is not valid
I am pasting my code. Kindly check the code and suggested that was I am doing right or wrong.
Image arr1 = byteArrayToImage(Bytess);
This is the function.
public static Image byteArrayToImage(byte[] byteArrayIn)
{
if (null == byteArrayIn || byteArrayIn.Length == 0)
return null;
MemoryStream ms = new MemoryStream(byteArrayIn);
try
{
Process currentProcess1 = Process.GetCurrentProcess();
Image returnImage = Image.FromStream(ms);
return returnImage;
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
I applied many techniques and solutions but it did not work for me
Your answer would be appreciated.
Thanks

try this
public Image byteArrayToImage(byte[] byteArrayIn)
{
System.Drawing.ImageConverter converter = new System.Drawing.ImageConverter();
Image img = (Image)converter.ConvertFrom(byteArrayIn);
return img;
}

After trying many things I found a way which has a little bit more control.
In this example you can specify the pixel format and copy the bytes to a Bitmap.
byte[] buffer = GetImageBytes();
var bitmap = new Bitmap(width, height, PixelFormat.Format32bppArgb);
var bitmap_data = bitmap.LockBits(new Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.WriteOnly, PixelFormat.Format32bppArgb);
Marshal.Copy(buffer, 0, bitmap_data.Scan0, buffer.Length);
bitmap.UnlockBits(bitmap_data);
var result = bitmap as Image;

The problem is because, you are bringing it incorrectly from database. Try changing your code like this:
while (registry.Read())
{
byte[] image = (byte[])registry["Image"];
}

In my case I got the error since my base64 string had wrong encoding before calling Image.FromStream.
This worked for me in the end:
byte[] bytes = System.Convert.FromBase64String(base64ImageString);
using (MemoryStream ms = new MemoryStream(bytes))
{
var image = Image.FromStream(ms);
image.Save(filePath, System.Drawing.Imaging.ImageFormat.Png);
}

cmd.CommandText="SELECT * FROM `form_backimg` WHERE ACTIVE=1";
MySqlDataReader reader6= cmd.ExecuteReader();
if(reader6.Read())
{
code4 = (byte[])reader6["BACK_IMG"]; //BLOB FIELD NAME BACK_IMG
}
reader6.Close();
MemoryStream stream = new MemoryStream(code4); //code4 is a public byte[] defined on top
pictureBox3.Image = Image.FromStream(stream);

try this,
public Image byteArrayToImage(byte[] byteArrayIn)
{
Image returnImage = null;
using (MemoryStream ms = new MemoryStream(byteArrayIn))
{
returnImage = Image.FromStream(ms);
}
return returnImage;
}

C# Load JPG file, extract BitmapImage

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");
