[font=arial]Day 9[/font]
In the past 3 days, I added the ability to save the maze image to a bitmap file. Previously I used 96 DPI, which seems to be Windows' default, but this time I realized I can specify any DPI I want to in a bitmap file, so I picked 150 DPI because I thought it was a good compromise between resolution and file size. Then I decided to make the printable area of a letter size paper 8"x10", which results in 1200x1500 pixels -- a nice round number. I generated 10 mazes and saved them into a single PDF file.

Going back to Day 8, I tried out slayemin's suggestion by manually filling the centers with colors (Figure (16)). Does it look better? Note that this feature is not in the code yet; I wanted to first get people's opinions.

Yeah, that is *much* better.
