Code too slow, any help apreciated

6 posts in this topic

Hi,

this code takes about 2-2.5sec to execute. Any ideas how to speed it up?

Opt("PixelCoordMode", 0)
$begin = TimerInit()
$winsize = WinGetClientSize("[active]")
for $i = 0 to 63
$line = Mod($i,8)+1
$col = Ceiling(($i +1)/8)
$rgbleds[$i+1] =  StringRight(hex(PixelGetColor($line * int(($winsize[0]/2)/8),$col * ($winsize[1]/8))),6)
next
for $i = 0 to 63
$line = Mod($i,8)+1
$col = Ceiling(($i +1)/8)
$rgbleds[$i+65] = stringright(hex(PixelGetColor($line * int(($winsize[0]/2)/8) + int(($winsize[0]/2)), $col * ($winsize[1]/8))),6)
next
$dif = TimerDiff($begin)
ConsoleWrite($dif & @CR)

I made this http://www.youtube.com/watch?v=gtq_o76CT8A and I was planing to use this code to "transfer" winamp visualization to this board... It's actualy working but it's too slow... formating serial frames and sending takes about 8ms but pixelgetcolor takes 2.5sec :x

I can never work out that timerdiff, I think is telling me it takes 36+ milliseconds.

I have a lousey old AMD 64 single core

EDIT:

I just made a Array of 200 elements to get it going

4.6msecs for me here on a very old laptop. The result from the TimerDiff is in milliseconds, not seconds. Perhaps you're misinterpreting the results?


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.
