A PHP script which will create a folding pattern for you if you provide it with an image.

Folding the pattern turns a dull book into real art.

The program file for 'BookArtGenerator' is BookArtGenerator.php.

To run, it requires php 5.5 or higher and imagemagick.
The program was only tested on Linux, so I do not know if it works on Windows.
If you try it out, please report, so that I can update this information.

How to use:

Make sure you have php 5.5 (http://www.php.net/) or later installed.
Also make sure you have imagemagick (http://www.imagemagick.org/script/index.php) installed.

Copy the script into a new directory on your computer.

Put a png file which fulfills the following requirements into the directory where the script is:

• Without transparency
• In RGB mode
• With a not very detailed, dark object
• Object may contain holes, or consist of several simple shapes, but there may be no gaps which go from top of the picture to the bottom
• Object in front of a bright background
• Object's width-to-height ratio must be within reasonable limits, you cannot open a book endlessly ;-)
• If there are holes or gaps in the object, make sure that there are no more than 5 holes in every orthogonal line. Less will turn out better.

Examples of a good choice: continuously written short words, single letters, simple silhouettes, all black on white...
Examples of a bad choice: photo, colourful drawings with many details, words with more than 6 letters,...

Make sure you have the rights to reproduce the picture (for example, take a public domain picture from http://openclipart.org/ ).

Make sure you have the rights to execute scripts in the script directory.
On the command line, go into the directory where the script is and enter

php BookArtGenerator.php

Answer the questions regarding your book.
Be sure to have a ruler - and of course, the book - on hand.

When the program has finished, to preview the result, look into the file named *_preview.png. Don't worry too much about the aspect ratio, this will likely look distorted (too broad usually). Every page is represented by an orthogonal line. The spaces in between are just to separate the lines more clearly for easier controlling.
You will be able to control the aspect ratio of the final result by opening your book wider or pushing it more closed.
Only check if the details are all there and if the alternating page folding pattern creation has worked.
To fold your pattern, follow the instructions in *_pattern.png.

If you make a beautiful object of art, please don't hesitate to send me a picture!
