Problem runing bitmap with Scan0 and System.IntPtr!!

one thing to keep in mind when using Lock() is the bitdepth of the colors in the image. You can look at this post for more info+code: http://216.26.160.137/Forums/AspNetForums20/ShowPost.aspx?PostID=13560 check the last post in this topic.

this worked for me but this is also a complete image i am also bitshifting beausethe image is 10bit ppixel in r g b unsafe { Rectangle rect = new Rectangle(0, 0, image.Width, image.Height); System.Drawing.Imaging.BitmapData bmpData = image.LockBits(rect, System.Drawing.Imaging.ImageLockMode.ReadWrite, image.PixelFormat); int ints = image.Width * image.Height ; IntPtr ptr = bmpData.Scan0; if (dmh.imageInfo.channel1.bits_per_pixel == 10) { for (int y = 0; y < ypix; y++) { for (int x = 0; x < xpix; x++) { tmp = InputStream.ReadUInt32(); tmp2 = Endianint(tmp); pixel = ((((tmp2 >> 8) & 0x00ff0000) + ((tmp2 >> 6) & 0x0000ff00) + ((tmp2 >> 4) & 0x000000ff))); //image.SetPixel(x, y, Color.FromArgb((int)pixel)); buf1[count] = (int)pixel; count++; } } } else if (dmh.imageInfo.channel1.bits_per_pixel == 8) { for (int y = 0; y < ypix; y++) { for (int x = 0; x < xpix; x++) { tmp = InputStream.ReadUInt32(); tmp2 = Endianint(tmp); pixel = ((((tmp2 >> 8) & 0x00ff0000) + ((tmp2 >> 8) & 0x0000ff00) + ((tmp2 >> 8) & 0x000000ff))); //image.SetPixel(x, y, Color.FromArgb((int)pixel)); buf1[count] = (int)pixel; count++; } } } Marshal.Copy(buf1, 0, ptr, ints); image.UnlockBits(bmpData); }
