convert gdcm_image to .NET bitmap fail

Hi am trying to get bitmap to display from DICOM file , but when try to create bitmap from the buffer I get Parameter is not valid for the Bitmap constructor call. I use the following code
gdcm.ImageReader reader = new gdcm.ImageReader();
reader.SetFileName(_dicomFilePath);
if (reader.Read())
{
var image = reader.GetImage();
if (image != null)
{
byte[] imageByteArray = new byte[image.GetBufferLength()];
if (image.GetBuffer(imageByteArray))
{
MemoryStream stream = new MemoryStream();
stream.Write(imageByteArray, 0, imageByteArray.Length);
stream.Seek(0, SeekOrigin.Begin);
Bitmap bmp = new Bitmap(stream);
CurrentFrameDataGDCM = Imaging.CreateBitmapSourceFromHBitmap(
bmp.GetHbitmap(),
IntPtr.Zero,
Int32Rect.Empty,
BitmapSizeOptions.FromWidthAndHeight((int)image.GetRows(), (int)image.GetColumns()));
}
}
}

Converting image from project folder

I am trying to convert a image in my image folder and the image name defaultImage and update into my database table.
But now I am having problem in this line of code:
I change the code using this:
Image uploaded6 = Image.FromFile("/image/defaultImage.jpg");
instead of this:
System.Drawing.Image uploaded = System.Drawing.Image.FromStream(~/images/defaultImage);
I now getting the error of FileNotFoundException was unhandled by user code
I have tried this method using fileupload control and it working fine but not sure how to convert image in a folder.
How do I get the image from the folder in order to convert it using the method shown below.
Image uploaded6 = Image.FromFile("/image/defaultImage.jpg");
//System.Drawing.Image uploaded = System.Drawing.Image.FromStream();
System.Drawing.Image newImage = new Bitmap(1024, 768);
using (Graphics g = Graphics.FromImage(newImage))
{
g.InterpolationMode = InterpolationMode.HighQualityBicubic;
g.DrawImage(uploaded, 0, 0, 1024, 768);
}
byte[] results;
using (MemoryStream ms = new MemoryStream())
{
ImageCodecInfo codec = ImageCodecInfo.GetImageEncoders().FirstOrDefault(c => c.FormatID == ImageFormat.Jpeg.Guid);
EncoderParameters jpegParms = new EncoderParameters(1);
jpegParms.Param[0] = new EncoderParameter(Encoder.Quality, 95L);
newImage.Save(ms, codec, jpegParms);
results = ms.ToArray();
}
string sqlImage = "update MemberReport set image1 = #Data where memberreportid = '" + Session["memberreportid"] + "'";
SqlCommand cmdImage = new SqlCommand(sqlImage);
cmdImage.Parameters.AddWithValue("#Data", results);
InsertUpdateData(cmdImage);

I guess your problem is with relative paths, instead of
Image uploaded6 = Image.FromFile("/image/defaultImage.jpg");
you should provide the local path, which you can get it this way:
Image uploaded6 = Image.FromFile(Server.MapPath("~/image/defaultImage.jpg"));

System.Drawing.Image.FromStream requires 'MemoryStream' as parameter.
byte[] file = null;
MemoryStream memoryStream = new MemoryStream();
memoryStream = new MemoryStream(file, false);
System.Drawing.Image objTempImg = System.Drawing.Image.FromStream(memoryStream)
byte[] file is based64 image

System.Drawing.Image.FromStream(Stream)
You must to send a Stream parameter in this method.

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;
}

Retrieve Image from SQL Server & set to PictureBox Image Property

I want to retrieve image from SQL Server(Database) using Entity Framework and set it to PictureBox Image Property
I have maked a user control & inherit it to PictureBox (Name:DisplayImage)
public static void LoadDisplay(Guid? DisplayID, string Name, byte[] image)
{
DisplayImage objDisplayImage = new DisplayImage();
DisplayList.Add(objDisplayImage);
objDisplayImage.Name = Name;
MemoryStream ms = new MemoryStream(image);
Image myImage = Image.FromStream(ms);
objDisplayImage.Image = myImage;
objDisplayImage.DisplayID = DisplayID;
PlayerForm.Instance.Controls.Add(objDisplayImage);
}
but Image is not loading on PictureBox

Try this code
try
{
// get image from object
byte[] _ImageData = new byte[0];
_ImageData = (byte[])_SqlRetVal;
System.IO.MemoryStream _MemoryStream = new System.IO.MemoryStream(_ImageData);
_Image = System.Drawing.Image.FromStream(_MemoryStream);
}
catch (Exception _Exception)
{
// Error occurred while trying to create image
// send error message to console (change below line to customize error handling)
Console.WriteLine(_Exception.Message);
return null;
}

A generic error occurred in GDI+

I loaded an image into a Picture Box using:
picturebox1.Image = Image.FromFile()
and I save it by using:
Bitmap bm = new Bitmap(pictureBox1.Image);
bm.Save(FileName, ImageFormat.Bmp);
It works perfectly fine when creating a new file, but when I try to replace the existing image, I get thrown the following runtime error:
A generic error occurred in GDI+
So what can I do to solve this problem??

That because the image file is used by your picturebox1.Image, try to save it to different file path instead:
picturebox1.Image = Image.FromFile(FileName);
Bitmap bm = new Bitmap(pictureBox1.Image);
bm.Save(#"New File Name", ImageFormat.Bmp);
Edit: You could also add a copy from the image at the first place like:
picturebox1.Image = new Bitmap(Image.FromFile(FileName));
Bitmap bm = new Bitmap(pictureBox1.Image);
bm.Save(FileName, ImageFormat.Bmp);//no error will occurs here.

The FromFile method locks the file, so use the Image.FromStream() method for reading the image:
byte[] bytes = System.IO.File.ReadAllBytes(filename);
System.IO.MemoryStream ms = new System.IO.MemoryStream(bytes);
pictureBox1.Image = Image.FromStream(ms);
Then save like you were before.

This can also happen if the path does not exist.
You could create the dir with:
System.IO.Directory.CreateDirectory(System.IO.Path.GetDirectoryName(FileName));

When either a Bitmap object or an Image object is constructed from a file, the file remains locked for the lifetime of the object. As a result, you cannot change an image and save it back to the same file where it originated. http://support.microsoft.com/?id=814675
A generic error occurred in GDI+, JPEG Image to MemoryStream:
Image.Save(..) // throws a GDI+ exception because the memory stream is closed
http://alperguc.blogspot.in/2008/11/c-generic-error-occurred-in-gdi.html
EDIT: Just writing from memory. Saving to an 'intermediary' MemoryStream should work:
For example, replace this:
Bitmap newBitmap = new Bitmap(thumbBMP);
thumbBMP.Dispose();
thumbBMP = null;
newBitmap.Save("~/image/thumbs/" + "t" + objPropBannerImage.ImageId, ImageFormat.Jpeg);
with something like:
string outputFileName = "...";
using (MemoryStream memory = new MemoryStream())
{
using (FileStream fs = new FileStream(outputFileName, FileMode.Create, FileAccess.ReadWrite))
{
thumbBMP.Save(memory, ImageFormat.Jpeg);
byte[] bytes = memory.ToArray();
fs.Write(bytes, 0, bytes.Length);
}
}

try this.
picturebox1.Image = Image.FromFile(FileName);
Bitmap bm = new Bitmat(pictureBox1.Image);
Image img = (Image)b;
img.Save(FileName, ImageFormat.Bmp);

Just like #Jalal Aldeen Saa'd said, the picture box is using the file and locked from file replacement.
//unlock file by clearing it from picture box
if (picturebox1.Image != null)
{
picturebox1.Image.Dispose();
picturebox1.Image = null;
}
//put back the picture inside the pictureBox?

try this it will work
public void SavePicture()
{
Bitmap bm = new Bitmap(this.myBitmap)
bm.Save("Output\\out.bmp" ,System.Drawing.Imaging.ImageFormat.Bmp );
}

This can also happen if you forget to add the filename:
bm.Save(#"C:\Temp\Download", System.Drawing.Imaging.ImageFormat.Png);
And can be fixed by adding the file name:
bm.Save(#"C:\Temp\Download\Image.png", System.Drawing.Imaging.ImageFormat.Png);
Note: You don't actually have to add the extension for it to work.

Try this:
private void LoadPictureBoxWithImage( string ImagePath)
{
Stream objInputImageStream = null;
BitmapData bmdImageData = null;
Bitmap bmpSrcImage = null, bmTemp = null;
byte[] arrImageBytes = null;
int bppModifier = 3;
try
{
objInputImageStream = new MemoryStream();
using (FileStream objFile = new FileStream(ImagePath, FileMode.Open, FileAccess.Read))
{
objFile.CopyTo(objInputImageStream);
}
bmpSrcImage = new Bitmap(objInputImageStream);
bppModifier = bmpSrcImage.PixelFormat == PixelFormat.Format24bppRgb ? 3 : 4;
//reda from byte[] to bitmap
bmdImageData = bmpSrcImage.LockBits(new Rectangle(0, 0, bmpSrcImage.Width, bmpSrcImage.Height), ImageLockMode.ReadOnly, bmpSrcImage.PixelFormat);
arrImageBytes = new byte[Math.Abs(bmdImageData.Stride) * bmpSrcImage.Height];
System.Runtime.InteropServices.Marshal.Copy(bmdImageData.Scan0, arrImageBytes, 0, arrImageBytes.Length);
bmpSrcImage.UnlockBits(bmdImageData);
pbSetup.Image = (Bitmap)bmpSrcImage.Clone();
pbSetup.Refresh();
}
catch (Exception ex)
{
throw new Exception("Error in Function " + System.Reflection.MethodInfo.GetCurrentMethod().Name + "; " + ex.Message);
}
finally
{
if (objInputImageStream != null)
{
objInputImageStream.Dispose();
objInputImageStream = null;
}
if (bmdImageData != null)
{
bmdImageData = null;
}
if (bmpSrcImage != null)
{
bmpSrcImage.Dispose();
bmpSrcImage = null;
}
if (bmTemp != null)
{
bmTemp.Dispose();
bmTemp = null;
}
if (arrImageBytes != null)
{
arrImageBytes = null;
}
}
}

A generic error occurred in GDI+
I also faced the same issue. I tried so many ways to fix this issue. Finally, I found a place where I have gone wrong. The problem is that I used space in the file path, which is not acceptable. Now it is working fine after removing the space in front of C after the apostrophe:
"SupplyItems":"C:\\inetpub\\HIBMS_Ver1\\BarcodeImages\\Supply\\"
instead... I used below one.
"SupplyItems":" C:\\inetpub\\HIBMS_Ver1\\BarcodeImages\\Supply\\"
Minor mistake but took a long time to find and to fix it.

Note that images created by Image.Clone() will still cause GDI+ errors as shown by the BAD code below, you must use the Image.FromStream() method for reading the image as shown in the solution on this page.
//BAD CODE: the image we will try to save AFTER the original image has been cloned and disposed
Image clonedImage;
//load image from file, clone it then dispose
using (var loadedFromDiskImage = Image.FromFile(filePath))
{
clonedImage = (Image) loadedFromDiskImage.Clone();
}
//you might think the new image can be saved given the original is disposed
//but this doesn't seem to be the way Clone() works
//expect GDI+ error in line below:
clonedImage.Save(filePath);
