Random pixel generator

[dreaper21]

Ok i need help!

 

Im trying to create a program that generates random pixels from a set picture.. i know how to write a random number generator its just figuring out how to take that one step further and getting it to grab pixels from a picture and show them one by one when somebody clicks generate button.

 

there needs to be 1,000,000 pixels in total. Raar my head hurts trying to think of a way to do it!  ???

 

if ne1 could help would be great!

PHP sounds like the worst language to use to do this, but hey, lets think...

 

You can use the GD library [http://uk.php.net/gd] measure the width and height of the image, then use:

 

get_pixel( random(0,width), random(0,height)

 

over and over?

 

If I were you I'd write this in c, then call it from the system() command.

If i knew how to program in C then id have a go at it!

 

il do a test of the method you suggest and see how that goes

i could try link up the get_pixel command to a front end button for the users to click on

 

all i can do is try!

 

cheers for advice

why would a user want a web app to find a random pixel in their picture? Sounds like madness.

tis for a charity event.

users give a quid to charity and 1 pixel appears.. the pixels have all the sponsors logos on it.

So if I pay £1,000,000 I get to see all the sponsor logos?

 

Or just random pixels?
