File:Example of ASCII-art turned into a bitmap.pbm.png

This is a bitmap file generated thus:

The following code, which is identifiable to the human eye as being primitive ASCII art representing the letter "J" in a pattern of ones, is pasted into a text editor and saved as Example_of_ASCII-art_turned_into_a_bitmap.pbm.

P1
# J
6 10
0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0
0 0 0 0 1 0

1 0 0 0 1 0
0 1 1 1 0 0
0 0 0 0 0 0
0 0 0 0 0 0

This produces a 143-byte Portable bitmap image file displaying a black "J" on a white background.

This file is then converted to PNG in a compatible image-editing program (e.g. IrfanView) in order to able to display it online.

Here is this image magnified 20 times.
