drawing on iphone -

-

I am trying to develop an iPhone application for children who are able to touch the characters on the screen and I want to know how to match the character created with the good character of the alphabet. How do I compare two sizes (drawing and existing) any thoughts ?? Some code?

You can create a list and it will calculate a metric between an input point "alphabet" You predefined it.

The GL gestorer is an objective-implementation of a $ 1 unistocrat identifier, a simple gesture recognition algorithm (see credit below). It is available here as an iPhone application project. It was implemented by Adam Prabal during an afternoon afternoon in late April 2009.

A demo iPhone project (gesture. Xcodeproj) has been provided; A UIView subclass receives touch events and sends them to the GLGestureRecognizer class, while drawing the hiding path in white, after the gesture is complete, the Risalpal gesture is shown in green, its center at the red dot, the best match With the name, the score is less (better), and gestation orientation. Example sample size of 16 digits is used, which is enough for very basic shapes.

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
