Export map array as Bitmap

I have noticed that people have expressed an interest in getting an image of the generated map to pass into Unity3D. So I have updated the Github link to add a new function to the class?csCaveGenerator.cs, that when called generates a bitmap of the map array, and I have pasted it below for your interest.

/// <summary>
/// Generate a bitmap from the contents of the map array
/// </summary>
/// <returns></returns>
public Bitmap GetMapImage()
//adjust to change the pixel size on the image
Size blocksize = new Size(5, 5);

Bitmap bmp = new Bitmap(MapSize.Width * blocksize.Width, MapSize.Height * blocksize.Height);
using (Graphics g = Graphics.FromImage(bmp))
using (SolidBrush sbBlack = new SolidBrush(Color.Black))
for (int x = 0; x < MapSize.Width; x++)
for (int y = 0; y < MapSize.Height; y++)
if (Map[x, y] == 1)
g.FillRectangle(sbBlack, new Rectangle(x * blocksize.Width, y * blocksize.Height, blocksize.Width, blocksize.Height));

  1. We met at the armchair philosophers meetup last night. Here is the tutorial series I was talking about that explains how to use meshes as a tile map
