In a word: Build a 1024*1024 color matrix with limited code, show your programming & Art Beauty

One of the problems that originated in Stackexchange is a bit of an extension that supports more programming languages and relaxes the limits of code length.

By implementing a function Get_color_at (x, y) in the template, draw the "interesting" pattern on a 1024*1024 canvas.

int x, int y, values are 0-1023, corresponding to the canvas on the punctuation, the upper left corner is the starting point (0,0)

int r, int g, int b, int alpha, RGBA component of corresponding color, all 0-255.

The alpha component definitions in each language may be different, and the unified conversion of the template to: 0-255, the greater the value the more transparent.

You can only edit code in the Get_color_at (x, y) function body/{{Code start}}-//{{code end}} in the template;
The total number of code characters cannot exceed 1024, and is of good readability.
