Picture --> Array -->File and back

[iamtheky 726]

in my use i am loading icons to arrays from text files and splashing them in all fun like.

There is about a 15 second lag time per 90x90 array during the _load() function.

Demo:

expandcollapse popup

#include <Array.au3>
Dim $BArray[90][90]

$merlin = _PicToArray(RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\AutoIt v3\AutoIt", "InstallDir") & "\Examples\GUI\merlin.gif")

_save($merlin , "C:\test\merlin.txt")

$oobe = _PicToArray(RegRead("HKEY_LOCAL_MACHINE\SOFTWARE\AutoIt v3\AutoIt", "InstallDir") & "\Examples\GUI\msoobe.jpg")

_save($oobe , "C:\test\oobe.txt")

$fromFile1 = _load("c:\test\merlin.txt" , $BArray)

$fromFile2 = _load("c:\test\oobe.txt" , $BArray)

Dim $ZArray[8100][3]
$k = 0
For $i = 0 To 89
    For $j = 0 To 89
        $ZArray[$k][0] = Random(0,10000,1)
        $ZArray[$k][1] = $i
        $ZArray[$k][2] = $j
        $k+=1
    Next
Next
_ArraySort($ZArray)


_DrawPicfromArray ($fromfile1, '15000')

_DrawPicfromArray ($fromfile2, '15000')

    For $i = 0 To 8099
        $D = $ZArray[$i][1]
        $E = $ZArray[$i][2]
        _PixelSetColor($D, $E, $Srcarray[$D][$E])
        _HPSleep(100,0)
    Next
  DllCall("user32.dll", "int", "ReleaseDC", "hwnd", 0, "hwnd", $dc[0])

Split into Save section and Load section
