java conversion help

I tried to integrate that into my code but got the same error. I am thinking that I am pulling the information incorrectly. Here is the code that read and interpolates the data. Is there something in there that jumps out at you? virtual public DicomData Data { set { if (debug_level > 3) System.Windows.Forms.MessageBox.Show("Now set width and height...."); width = System.Int32.Parse(value.getAnalyzedValue("(0028,0011)")); height = System.Int32.Parse(value.getAnalyzedValue("(0028,0010)")); defaultWidth = width; defaultHeight = height; if (debug_level > 3) System.Windows.Forms.MessageBox.Show("Image width : " + width); if (debug_level > 3) System.Windows.Forms.MessageBox.Show("Image heigth : " + height); if (debug_level > 3) System.Console.Out.Write("Now set byte[] to int[]...."); orgPixel = new int[width * height]; pixLength = orgPixel.Length; pixel = new int[pixLength]; defaultPixel = new int[pixLength]; sbyte[] tmpValue = new sbyte[value.getValue("(7fe0,0010)").Length]; Array.Copy(value.getValue("(7fe0,0010)"), 0, tmpValue, 0, tmpValue.Length); //read the image(s) from the struct if (debug_level > 3) System.Windows.Forms.MessageBox.Show(" OK!"); // (0028,0004)Photometric Interpretation ‚RGB if (value.isContain("(0028,0004)") && value.getAnalyzedValue("(0028,0004)").Trim().Equals("RGB")) { rgbMode = true; for (int i = 0; i < pixLength; i++) { // multiply 3 * i for samples per pixel times i to get the next value one for red green and blue orgPixel[i] = ((255 << 24) | (0xff & tmpValue[3 * i]) << 16 | (0xff & tmpValue[(3 * i) + 1]) << 8 | (0xff & tmpValue[(3 * i) + 2])); } } else { if (value.getAnalyzedValue("(0028,0100)").Trim().Equals("16")) { short shValue = 0; for (int i = 0; i < pixLength; i++) { shValue = (short) ((0xff & tmpValue[(2 * i) + 1]) << 8 | (0xff & tmpValue[2 * i])); orgPixel[i] = (int) shValue; } } else { for (int i = 0; i < pixLength; i++) orgPixel[i] = (int) (0xff & tmpValue[i]); } int bit_stored = System.Int32.Parse(value.getAnalyzedValue("(0028,0101)")); int bit_hight = System.Int32.Parse(value.getAnalyzedValue("(0028,0102)")); int bit_gap = bit_hight - bit_stored + 1; if (bit_gap > 0) { for (int i = 0; i < pixLength; i++) orgPixel[i] = (orgPixel[i] >> bit_gap); } } Array.Copy((System.Array) orgPixel, 0, (System.Array) defaultPixel, 0, pixLength); //tmpValue = null; if (debug_level > 3) System.Console.Out.Write("Now set pixelMin and pixelMax...."); pixelMin = 0; pixelMax = 0; for (int i = 0; i < pixLength; i++) { if (pixelMin > orgPixel[i]) pixelMin = orgPixel[i]; if (pixelMax < orgPixel[i]) pixelMax = orgPixel[i]; } if (debug_level > 3) System.Windows.Forms.MessageBox.Show(" OK!"); if (debug_level > 3) System.Console.Out.Write("Now set WW/WL...."); if (value.isContain("(0028,1051)")) { try { ww = System.Int32.Parse(value.getAnalyzedValue("(0028,1051)").Replace('+', ' ').Trim()); } catch (System.FormatException e) { ww = pixelMax - pixelMin; } } else { ww = pixelMax - pixelMin; } if (value.isContain("(0028,1050)")) { try { wl = System.Int32.Parse(value.getAnalyzedValue("(0028,1050)").Replace('+', ' ').Trim()); } catch (System.FormatException e) { wl = (ww >> 1) + pixelMin; } } else { wl = (ww >> 1) + pixelMin; } defaultWW = ww; defaultWL = wl; if (debug_level > 3) System.Windows.Forms.MessageBox.Show(" OK!"); if (debug_level > 3) System.Windows.Forms.MessageBox.Show("WW :" + ww + " WL :" + wl); for (int i = 0; i < pixel.Length; i++) pixel[i] = (int) SupportClass.Identity(0xff000000); try { System.Runtime.Serialization.Formatters.Binary.BinaryFormatter b = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter(); //byte[] temp = SupportClass.ToByteArray(tmpValue); System.IO.MemoryStream istream = new System.IO.MemoryStream(); b.Serialize(istream, pixel); //istream.Position = 0; //System.IO.FileStream fs = new System.IO.FileStream("temp.img", System.IO.FileMode.Create); //b.Serialize(istream, pixel); image = System.Drawing.Image.FromStream(istream,false); //w.Close(); //fs.Close(); } catch (System.Exception ex){ System.Windows.Forms.MessageBox.Show("Making Image : " + ex.Message); } //UPGRADE_ISSUE: Constructor 'java.awt.image.MemoryImageSource.MemoryImageSource' was not converted.

Here is code that I tried that works. The only difference is how I fill the MemoryStream object. You can INSERT this code into your block before the Image.FromStream() and see if it works with a known good image object. FileStream fs = new FileStream("c:\\test.bmp", FileMode.Open, FileAccess.Read, FileShare.ReadWrite); byte[] buf = new byte[fs.Length]; fs.Read(buf, (int) 0, (int) fs.Length); MemoryStream ms = new MemoryStream(buf); Image img = Image.FromStream(ms); this.BackgroundImage = img;

I am pretty sure that it is a valid image. I am using some other code that is ported from java and the java code works. How exactly would I check to see that what I am trying to load is valid? I can try to read a jpeg image from binary but, am not quite sure how to do that. That is the only thing that I can think of to test the code to make sure that it works. Any other suggestions?

This is a runtime error, is it not? That would mean that your MemoryStream does not contain a valid image. This code will do what you're describing. It obviously has no valid image in the memory stream. { MemoryStream mstream = new MemoryStream(); System.Drawing.Image.FromStream(mstream); }
