Creating a Bitmap that is really small (3 x 6 in this case). I need to display it in a picture box without antialiasing. Here is how I am scaling now:

image = new System.Drawing.Bitmap(image, image.Width * 10, image.Height * 10);

The resulting image is very munged:

The image is built using 0 - 255 RGB using the data below:

  2 |  1 |

  2 | 12 |

  1 | 16 |

  3 |  5 |

  2 |  6 |

  3 |  4 |

The pixel color is set by making the highest number (16) = 255, 255,2555 with zero being 0,0,0 or black.

Full code:

        public System.Drawing.Bitmap SliceBMP(Slice s, Axis axis = Axis.x)

    {

        s = CheckSlice(s);

        int max = GetMaxCount(s);

        System.Drawing.Bitmap image = new System.Drawing.Bitmap(s.ZEnd - s.ZBegin + 1, s.YEnd-s.YBegin+1 );

        switch (axis)

        {

            case Axis.x:

                for (int b = s.YBegin; b <= s.YEnd; b++)

                    {

                    for (int c = s.ZBegin; c <= s.ZEnd; c++)

                    {

                        double count = (double)_grid[s.XBegin][b][c].Count;

                        int color = (int)((count / max)*500.0);

                        if(color > 255)

                        {

                            color = 255;

                        }

                        image.SetPixel(

                            c - s.ZBegin, 

                            s.YEnd - b, 

                            System.Drawing.Color.FromArgb(color, color, color)

                            );



                     }

                }

                break;



        }

        image = new System.Drawing.Bitmap(image, image.Width * 10, image.Height * 10);

        return image;

    }

Where it's called:

        pictureBox1.Image = sliceImage;

        pictureBox1.Width = sliceImage.Width;

        pictureBox1.Height = sliceImage.Height;

        pictureBox1.Refresh();
