How can I export a high resolution image

How can I export a high resolution image?
Any suggestion using:


I searched on python forums and they all point to an additional module (Pillow).

Here’s the simple native .NET method, see further down for the the more advanced lockbits method:

What could be wrong?

import rhinoscriptsyntax as rs
import Rhino
import scriptcontext as sc
import time
from System.Drawing import Bitmap
import System
import System.Drawing as sd
import math
from System.Drawing import Color

bm = sd.Bitmap(resx,resy)
color = sd.Color
for x in xrange(resy*resx):
	j = x // resx
	i = x % resx
	color = cores[x][0], cores[x][1], cores[x][2]
	bm.SetPixel(i, j, color)
bm.Save("c:\\users\\public\\test.jpg", sd.Imaging.ImageFormat.Jpeg)

Message: expected Color, got tuple

line 110, in moveup3D2img, “C:\Users\cristiano.pasini\Downloads\”
line 122, in , “C:\Users\cristiano.pasini\Downloads\”

color = sd.Color.FromArgb(255, cores[x][0], cores[x][1], cores[x][2])

It Works!!!
