Avg Bid (USD)
Project Budget (USD)
$250 - $750

Project Description:
We are looking for an experience Perl coder who can develop for us a heat generation script written in Perl

The heat map will show the temperature in a server room floor map (created as a PNG file) similar as this one: https://s3.amazonaws.com/serverscheck-temp/vworker.png

The current readings will be made available as a file with following structure:
line 1: PNG Image file name
First line is the name of the PNG on which to draw the overlay heat map
Following lines are the X & Y positions of the sensors and their current reading

Coloring ranges from blue (cool) to green (normal) and red (overheat) We will provide with what that scale is. The spread of each sensor (in pixels) has to be configurable in the script as this will largely depend on the scale at which the floor map was made.

Complexity is that the heat map shouldn't dissipate over a rack. Color coding of a rack will be an area ranging from gray to black like in the above picture.
