How to load an image to RAM

1 post in this topic

My problem is:

I use ImageSearch.dll to search an image on desktop

and this is ImageSearch.au3

#include-once
; ------------------------------------------------------------------------------
;
; AutoIt Version: 3.0
; Language:    English
; Description:  Functions that assist with Image Search
;                Require that the ImageSearchDLL.dll be loadable
;
; ------------------------------------------------------------------------------
;===============================================================================
;
; Description:    Find the position of an image on the desktop
; Syntax:          _ImageSearchArea, _ImageSearch
; Parameter(s): 
;                  $findImage - the image to locate on the desktop
;                  $tolerance - 0 for no tolerance (0-255). Needed when colors of
;                               image differ from desktop. e.g GIF
;                  $resultPosition - Set where the returned x,y location of the image is.
;                                    1 for centre of image, 0 for top left of image
;                  $x $y - Return the x and y location of the image
;
; Return Value(s):  On Success - Returns 1
;                  On Failure - Returns 0
;
; Note: Use _ImageSearch to search the entire desktop, _ImageSearchArea to specify
;      a desktop region to search
;
;===============================================================================
Func _ImageSearch($findImage,$resultPosition,ByRef $x, ByRef $y,$tolerance)
   return _ImageSearchArea($findImage,$resultPosition,0,0,@DesktopWidth,@DesktopHeight,$x,$y,$tolerance)
EndFunc
Func _ImageSearchMouseArea($findImage,$resultPosition,$radius,ByRef $x, ByRef $y, $tolerance)
    Return _ImageSearchArea($findImage,$resultPosition,MouseGetPos(0)-$radius,MouseGetPos(1)-$radius,MouseGetPos(0)+$radius,MouseGetPos(1)+$radius,$x,$y,$tolerance)
EndFunc

Func _ImageSearchArea($findImage,$resultPosition,$x1,$y1,$right,$bottom,ByRef $x, ByRef $y, $tolerance)
;MsgBox(0,"asd","" & $x1 & " " & $y1 & " " & $right & " " & $bottom)
if $tolerance>0 then $findImage = "*" & $tolerance & " " & $findImage
$result = DllCall("ImageSearchDLL.dll","str","ImageSearch","int",$x1,"int",$y1,"int",$right,"int",$bottom,"str",$findImage)
; If error exit
    if $result[0]="0" then return 0

; Otherwise get the x,y location of the match and the size of the image to
; compute the centre of search
$array = StringSplit($result[0],"|")
  
   $x=Int(Number($array[2]))
   $y=Int(Number($array[3]))
   if $resultPosition=1 then
      $x=$x + Int(Number($array[4])/2)
      $y=$y + Int(Number($array[5])/2)
   endif
   return 1
EndFunc

; Description:    Wait for a specified number of seconds for an image to appear

; Syntax:          _WaitForImageSearch, _WaitForImagesSearch

Func _WaitForImageSearch($findImage,$waitSecs,$resultPosition,ByRef $x, ByRef $y,$tolerance)
$waitSecs = $waitSecs * 1
$startTime=TimerInit()
While TimerDiff($startTime) < $waitSecs
  sleep(100)
  $result=_ImageSearch($findImage,$resultPosition,$x, $y,$tolerance)
  if $result > 0 Then
   return 1
  EndIf

return 0
EndFunc

; Description:    Wait for a specified number of seconds for any of a set of
;                  images to appear
;   
; Syntax:          _WaitForImagesSearch
; Parameter(s): 
;    $waitSecs  - seconds to try and find the image
;                  $findImage - the ARRAY of images to locate on the desktop
;                             - ARRAY[0] is set to the number of images to loop through
;        ARRAY[1] is the first image
;                  $tolerance - 0 for no tolerance (0-255). Needed when colors of
;                               image differ from desktop. e.g GIF
;                  $resultPosition - Set where the returned x,y location of the image is.
;                                    1 for centre of image, 0 for top left of image

Func _WaitForImagesSearch($findImage,$waitSecs,$resultPosition,ByRef $x, ByRef $y,$tolerance)
$waitSecs = $waitSecs * 1
$startTime=TimerInit()
While TimerDiff($startTime) < $waitSecs
  for $i = 1 to $findImage[0]
      sleep(100)
      $result=_ImageSearch($findImage[$i],$resultPosition,$x, $y,$tolerance)
      if $result > 0 Then
       return $i
      EndIf
  Next
WEnd
return 0
EndFunc

and this is my Program just like this

#include <ImageSearch.au3>
$x1 = 0
$y1 = 0
$ImageToSearch = @Scriptdir &"\Image.bmp"
HotKeySet("x","_exit")
Sleep(7000)
$i = 1
While $i < 100000
      $res1 = _ImageSearch ($ImageToSearch ,1,$x1,$y1,100)
   If ($res1 = 1) Then
   Exit
   Else
   Call("_ChangeDesktop")
   EndIf
WEnd
Func _exit()
Exit
EndFunc

Func _ChangeDesktop()
   ;Dosomething to change desktop
   $i = $i + 1
EndFunc

Absolutely my program will load the Image.bmp in HardDrive 100000 times

I want to load the image to some where on RAM to low down the time of reading from Hard Drive

Please help

Sorry about my bad English!
