I haven't found means to contact the project owners directly, so I'm attaching
a patched Image.cs to this issue with added methods for those who are wondering
how to use JpegEncoder with Bitmaps generated by means of .NET code, and for
those who wish to load raster data from GDI+ supported image formats:
public static Image FromStream(Stream inStream)
{
using (Bitmap bmp = new Bitmap(Bitmap.FromStream(inStream)))
{
return FromBitmap(bmp);
}
}
public static Image FromFile(string filePath)
{
using (Bitmap bmp = new Bitmap(Bitmap.FromFile(filePath)))
{
return FromBitmap(bmp);
}
}
public static Image FromBitmap(Bitmap bitmap)
{
int width = bitmap.Width;
int height = bitmap.Height;
int bands = 3;
byte[][,] raster = new byte[bands][,];
for (int i = 0; i < bands; i++)
{
raster[i] = new byte[width, height];
}
BitmapData bd = bitmap.LockBits(new Rectangle(0, 0, bitmap.Width, bitmap.Height), ImageLockMode.ReadOnly, PixelFormat.Format32bppArgb);
int[] pixels = new int[bd.Width * bd.Height];
Marshal.Copy(bd.Scan0, pixels, 0, pixels.Length);
bitmap.UnlockBits(bd);
for (int row = 0; row < height; row++)
{
for (int column = 0; column < width; column++)
{
int pixel = pixels[width * row + column];
raster[0][column, row] = (byte)(pixel >> 16);
raster[1][column, row] = (byte)(pixel >> 8);
raster[2][column, row] = (byte)pixel;
}
}
ColorModel model = new ColorModel { colorspace = ColorSpace.RGB };
return new Image(model, raster);
}
Best wishes,
Ilya Melamed
