Alternative to System.Drawing.Bitmap for Xamarin Forms - forms

Question

I need to use Bitmap class from System.Drawing.Bitmap, this is a function that works fine on windows Platform. But after I tried to run on Xamarin Forms, and installed nuget package System.Drawing, the program compiles correctly without errors.
But when running program I receive an error. Somehow seems to point to System.Drawing from windows, not the System.Drawing from the nuget package.
What I need to do is, get Photo from Camera and print it.
Below is the code to print. Problem is with "Bitmap" converter.
Tried several nuget packages, none worked:
System.Drawing.Common
Fast-Bitmap
Bitmap.Net
public byte[] PrintImage(byte[] PHOTO)
{
Bitmap bmp;
using (var ms = new MemoryStream(PHOTO))
{
bmp = new Bitmap(ms);
}
BitmapData data = GetBitmapData(bmp);
BitArray dots = data.Dots;
byte[] width = BitConverter.GetBytes(data.Width);
int offset = 0;
MemoryStream stream = new MemoryStream();
BinaryWriter bw = new BinaryWriter(stream);
// center command
bw.Write(27);
bw.Write('a');
bw.Write(1);
// print image
bw.Write((char)0x1B);
bw.Write('#');
bw.Write((char)0x1B);
bw.Write('3');
bw.Write((byte)24);
while (offset < data.Height)
{
bw.Write((char)0x1B);
bw.Write('*'); // bit-image mode
bw.Write((byte)33); // 24-dot double-density
bw.Write(width[0]); // width low byte
bw.Write(width[1]); // width high byte
for (int x = 0; x < data.Width; ++x)
{
for (int k = 0; k < 3; ++k)
{
byte slice = 0;
for (int b = 0; b < 8; ++b)
{
int y = (((offset / 8) + k) * 8) + b;
// Calculate the location of the pixel.
// It'll be at (y * width) + x.
int i = (y * data.Width) + x;
// If the image is shorter than 24 dots.
bool v = false;
if (i < dots.Length)
{
v = dots[i];
}
slice |= (byte)((v ? 1 : 0) << (7 - b));
}
bw.Write(slice);
}
}
offset += 24;
bw.Write((char)0x0A);
}
// Restore the line spacing to the default of 30 dots.
bw.Write((char)0x1B);
bw.Write('3');
bw.Write((byte)30);
bw.Flush();
byte[] bytes = stream.ToArray();
return bytes; // logo + Encoding.Default.GetString(bytes);
}
public BitmapData GetBitmapData(Bitmap bmp) // (string bmpFileName)
{
//using (var bitmap = (Bitmap)Bitmap.FromFile(bmpFileName))
using (var bitmap = bmp)
{
var threshold = 127;
var index = 0;
double multiplier = 570; // this depends on your printer
double scale = (double)(multiplier / (double)bitmap.Width);
int xheight = (int)(bitmap.Height * scale);
int xwidth = (int)(bitmap.Width * scale);
var dimensions = xwidth * xheight;
var dots = new BitArray(dimensions);
for (var y = 0; y < xheight; y++)
{
for (var x = 0; x < xwidth; x++)
{
var _x = (int)(x / scale);
var _y = (int)(y / scale);
var color = bitmap.GetPixel(_x, _y);
var luminance = (int)(color.R * 0.3 + color.G * 0.59 + color.B * 0.11);
dots[index] = (luminance < threshold);
index++;
}
}
return new BitmapData()
{
Dots = dots,
Height = (int)(bitmap.Height * scale),
Width = (int)(bitmap.Width * scale)
};
}
}
public class BitmapData
{
public BitArray Dots
{
get;
set;
}
public int Height
{
get;
set;
}
public int Width
{
get;
set;
}
}
Error occurs when function is called as:
byte[] _buffer = PrintImage(FOTO);
The error:
"Could not resolve type with token 01000119 from typeref (expected class 'System.Drawing.Bitmap' in assembly 'System.Drawing.Common, Version=4.0.1.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51')"
