C # convert Raw (8-bit or 10-bit or 12-bit or 14-bit or 16-bit image) Bmp image

I have Raw Images files (Raw8 or Raw10 or Raw12 or Raw14 or Raw16 …). I want to convert Raw to BMP.

The code works but I still have problems with the results.

public void ReadImage (out byte[] Data, String Path, uint Width, uint Height, uint BPP) {
byte[] fileData = null;
if (! File.Exists (path))
{
launch a new FileNotFoundException (path);
}

fileData = File.ReadAllBytes (path);
var bytesPerPixel = (BPP + 7) / 8;
var dataSize = Width * Height * bytesPerPixel;
Data = new byte[Width * Height * bytesPerPixel];
var sdata = new short[dataSize / 2];
if (bytesPerPixel == 1)
{
for (int i = 0, shortIndex = 0; i <data size, i + = 2, shortIndex ++)
{
CopyBytesToShort (fileData[i], fileData[i + 1], excluding data[shortIndex], (int) BPP, false);
}
}
if (bytesPerPixel == 2)
{
for (int i = 0, shortIndex = 0; i <data size, i + = 2, shortIndex ++)
{
CopyBytesToShort (fileData[i], fileData[i + 1], excluding data[shortIndex], (int) BPP, true);
}
}
Buffer.BlockCopy (sdata, 0, Data, 0, Data.Length);
int w = Convert.ToInt32 (Width);
int h = Convert.ToInt32 (Height);
unsafe
{
fixed (byte * ptr = Data)
{
using (var bmp = new Bitmap (w / 4, h / 4, w * 4, PixelFormat.Format32bppRgb, new IntPtr (ptr)))
{

Bitmap dmybp = new Bitmap (bmp, new size (w, h));
dmybp.Save (@ "RAW.bmp", System.Drawing.Imaging.ImageFormat.Bmp);
}
}
}
}
private void CopyBytesToShort (octet byte1, byte byte2, short retshort, int bitsPerPixel, bool isPerformShift)
{
short lsb, msb;
lsb = octet1;
msb = byte2;
if (isPerformShift)
{
lsb << = 16 - bitsPerPixel;
msb << = (24 bitsPerPixel);
}
other
{
msb << = 8;
}
retShort = (short) (msb | lsb);
}

if I run with Raw8 can get a correct picture.enter the description of the image here

But when I run another RAW file (Raw10 or Raw12 or Raw14 or Raw16 …), I have a failure image.
Like that:

Please comment on the optimization of my code in C # and on the best way to convert an image.

How to display BMP images in a simple Java image viewer

I am newer in programming and try to make my image viewing program display BMP images. The program works for JPEG and PNG images but not for BMP. I commented on the attempts I made for BMP to work, which I found online. The methods I found online all seem to convert the BMP file to a PNG file. I would prefer that the image remains a BMP file, but if it is not possible, I would still like to make it work where it is converted to PNG. In addition, I know how to change the size of the image window but I do not know what determines the display size of the image or if there is a way to change that. I've included what I've got up to here below:

import javax.swing.JFileChooser;
import javax.swing.JLabel;
import javax.swing.JMenu;
import javax.swing.JMenuItem;
import java.awt.event. *;
import java.io. *;
import javax.swing. *;
import javax.imageio.ImageIO;


Public class ImageViewer {

public static void main (String[] args) {
JFrame frame = new ImageViewerFrame ();
frame.setTitle ("Image Viewer");
frame.setDefaultCloseOperation (JFrame.EXIT_ON_CLOSE);
frame.setVisible (true);
}
}


the ImageViewerFrame class extends JFrame {
JLabel label;
JFileChooser selector;
JMenuBar menu bar;
JMenu menu;
JMenuItem menuitem;

public ImageViewerFrame () {

setSize (500 500); // set the size of the window

label = new JLabel ();
add (label);

chooser = new JFileChooser ();
chooser.setCurrentDirectory (new file ("."));

menu bar = new JMenuBar ();
setJMenuBar (menu bar);

menu = new JMenu ("File");
menubar.add (menu);

menuitem = new JMenuItem ("Open");
menu.add (menuitem);

menuitem.addActionListener (new ActionListener () {
public void actionPerformed (ActionEvent event) {
int result = chooser.showOpenDialog (null);
if (result == JFileChooser.APPROVE_OPTION) {

// Image image = ImageIO.read

String name = chooser.getSelectedFile (). GetPath ();

// Image image = ImageIO.read (name);
// ImageIcon icon = new ImageIcon (name);
// JLabel test = new JLabel (icon);

label.setIcon (new ImageIcon (name)); // open the file

// ImageIcon icon = new ImageIcon (name);
// label.setIcon (new ImageIcon (icon));
}
}
});

}
}
