Random Bitmap Generator

This form allows you to generate random bitmaps. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.

Generate a bitmap in format [image file formats]

Use width and height pixels (maximum 300).

Zoom factor

The final image resolution will be (w × z) by (h × z) where w is the width, h is the height and z is the zoom factor.

Be patient! It may take a little while to generate your bitmap...
