<p style="color: grey"> Python recipe 205451 by <a href="/recipes/users/860809/">Simon Burton</a> (<a href="/recipes/tags/graphics/">graphics</a>). </p> <p>Here is a relatively simple framework for making povray files from your favourite programming language, python. It's good for creating structured/mathematical scenes and animations.</p>

<p style="color: grey"> Python recipe 442299 by <a href="/recipes/users/1759688/">S W</a> (<a href="/recipes/tags/graphics/">graphics</a>). </p> <p>Packing images of different sizes into one image is often required in order to efficiently use hardware accelerated texture mapping functions of 3D video cards.</p>

<p style="color: grey"> Python recipe 412982 by <a href="/recipes/users/1461790/">Rick Muller</a> (<a href="/recipes/tags/graphics/">graphics</a>). </p> <p>The Python Imaging Library (PIL) makes many tasks easy in digital photography. This recipe shows how to make a "contact sheet" of images, a single image with thumbnails of many different pictures. It's limited in that it will only work with pictures of the same shape, but you can make some really fun images.</p>

<p style="color: grey"> Python recipe 227575 by <a href="/recipes/users/1410328/">Simon Peverett</a> (<a href="/recipes/tags/graphics/">graphics</a>). </p> <p>Reads an image file from the filename specified as the 1st parameter on the command line and displays it on screen. Uses the PIL module so that it can load almost any image file type supported by that module and uses Tkinter to display the image on a Tkinter canvas.</p> <p>I'm new to Python so excuse the clunkyness of implementation.</p>

Revision 2. </p> <p>Random maze generator using depth-first search.</p> <p>It starts the maze path from a random cell and there is no exit defined but actually any 2 cells on the path (white cells) can be assigned to be entry and exit locations. (I could just add code to randomly select 2 white cells and change their colors to something else but I thought it looks better this way.)</p>
