[pygame] Surfarray Help

[Ian Mallett <geometrian@xxxxxxxxx>]

Hello,

I want to make a surface of size sqrt(n) on a side filled with special values.

The values range from 0.0 to 3.0, starting with 0.0 at one corner and ending at 3.0 in the opposite, increasing going row by row.  The value is to be encoded in each color.  Because this is somewhat abstract, here's a small example (n=25), generated using the attached code (it also multiplies the number by 255 to obtain a RGB color).  The real version should be done by surfarray.  This is where I need help; I have no idea how to even approach the problem.  

[[  0,  0,  0],[ 32,  0,  0],[ 64,  0,  0],[ 96,  0,  0],[128,  0,  0],
 [159,  0,  0],[191,  0,  0],[223,  0,  0],[255,  0,  0],[255, 32,  0],
 [255, 64,  0],[255, 96,  0],[255,128,  0],[255,159,  0],[255,191,  0],
 [255,223,  0],[255,255,  0],[255,255, 32],[255,255, 64],[255,255, 96],
 [255,255,128],[255,255,159],[255,255,191],[255,255,223],[255,255,255]]

Arrays like this need to be generated quite quickly, so the per-pixel method I presented will not work.  How should I do it with surfarray?

Thanks,
Ian
