- The language must be extremely College Essay About Knitting simple to design and implement (it is a didactic stuff indeed!);
- The language must be as simple as possible to learn and use: we won’t be an alternative to Pixel Bender (because we can’t … yet ;P)
- The language must be Manipulated In Fight Club quick to compile and execute.
- A script must accept some parmeters to control its behaviour.
- We must support comments!
- The first implementation of the language will support a http://www.valevafotografos.com/?research-papers-neo-colonialism-in-africa Research Papers Neo Colonialism In Africa sigle data type: Numbers. We will move further adding more data types later – I don’t want to focus on type checking yet.
- We will add support for basic expression operators, basic control flow. No support for functions yet.
- The language will provide some useful operators or http://www.fesp.org/?assignment-help-usa Assignment Help Usa builtin functions to manage common operations like packing/unpacking color components and peform some mathematical operations.
- Arguments to a script will be only Numbers at first.
- A script will be defined as a simple sequence of arguments followed by a function definition. This function will be applied sequentially to every pixel of one or more source images.
- We will provide to implementations for the language: a simple (and slow) interpreter at first, then we will generate native SWF code to speedup the performances.

// Simple crossfade filter
// The crossfade intensity
* A quick explanation of the used builtins:
* - in( id, x, y ): gets the ARGB color at x and y of the image identified by id (there can be more than one image as input);
* - out( id, x, y, color ): sets the ARGB color at x and y for the output image identified by id;
* - argb( a, r, b, b ): build an ARGB color from its components (clamping and rounding the values as required);
evaluatePixel( x, y )
// this kind of assignment is similar to the python unpack assignment
// but extracts the 4 components (ARGB) from a color.
a1, r1, g1, b1 = in( 0, x, y );
a2, r2, g2, b2 = in( 1, x, y );
out( 0, x, y, argb(
( 1 - intensity ) * a1 + intensity * a2,
( 1 - intensity ) * r1 + intensity * r2,
( 1 - intensity ) * g1 + intensity * g2,
( 1 - intensity ) * b1 + intensity * b2 ));
