C# convert Raw(8-bit or 10-bit or 12-bit or 14-bit or 16-bit) Image to bmp












0












$begingroup$


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



The code runs but I still have some issues with the results.



public void ReadImage(out byte Data, string path, uint Width, uint Height,uint BPP){
byte fileData = null;
if (!File.Exists(path))
{
throw 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 < dataSize; i += 2, shortIndex++)
{
CopyBytesToShort(fileData[i], fileData[i + 1], out sdata[shortIndex], (int)BPP, false);
}
}
if (bytesPerPixel == 2)
{
for (int i = 0, shortIndex = 0; i < dataSize; i += 2, shortIndex++)
{
CopyBytesToShort(fileData[i],fileData[i + 1], out sdata[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(byte byte1, byte byte2, out short retShort, int bitsPerPixel, bool isPerformShift)
{
short lsb, msb;
lsb = byte1;
msb = byte2;
if (isPerformShift)
{
lsb <<= 16 - bitsPerPixel;
msb <<= (24 - bitsPerPixel);
}
else
{
msb <<= 8;
}
retShort = (short)(msb | lsb);
}


if i run with Raw8 can get correct image.enter image description here



But when i run other RAW file(Raw10 or Raw12 or Raw14 or Raw16...), I got fail image.
Like this:
enter image description here



Please comment about about optimizing my code in C# and if there a better way to convert an image.
