Compare images

2 posts in this topic

#1 ·  Posted (edited)

I think here I need to put loop/arrays but im not so experienced in this.

Func works very good with two images but I need to compare 10 images.

Always is one main image and need to find same image as main. So if func returns false, loop to other image.

#include



_GDIPlus_Startup()

$mainimage = "C:Documents and SettingsMyDesktopAutoitnewSukarpyti skaiciaic0.bmp" ;main image, this img wont change


$fname1 = "C:Documents and SettingsvDesktopAutoitnewpicturesc1.bmp"


;=========experimenting
$fname2 = "C:Documents and SettingsMyDesktopAutoitnewpicturesc2.bmp"
$fname3 = "C:Documents and SettingsMyDesktopAutoitnewspicturesc3.bmp"
$fname4 = "C:Documents and SettingsMyDesktopAutoitnewpicturesc4.bmp"
$fname5 = "C:Documents and SettingsMyDesktopAutoitnewpicturesc5.bmp"
$fname6 = "C:Documents and SettingsvDesktopAutoitnewpicturesc6.bmp"      ;I think all these need to put into
$fname7 = "C:Documents and SettingsMyDesktopAutoitnewpicturesc7.bmp"     ; array and make loop
$fname8 = "C:Documents and SettingsMyDesktopAutoitnewapicturesc8.bmp"
$fname9 = "C:Documents and SettingsvDesktopAutoitnewpicturesc9.bmp"
$fname10 = "C:Documents and SettingsMyDesktopAutoitnewpicturesc10.bmp"
;=========experimenting

$bm1 = _GDIPlus_ImageLoadFromFile($mainimage) ; dont changes (main img)

;find for same img
$bm2 = _GDIPlus_ImageLoadFromFile($fname2)




MsgBox(0, "bm1==bm2", CompareBitmaps($bm1, $bm2)) ;shows if true or false, if it returns false then need to make to go for another img.


_GDIPlus_ImageDispose($bm1)
_GDIPlus_ImageDispose($bm2)
_GDIPlus_Shutdown()

Func CompareBitmaps($bm1, $bm2)

$Bm1W = _GDIPlus_ImageGetWidth($bm1)
$Bm1H = _GDIPlus_ImageGetHeight($bm1)
$BitmapData1 = _GDIPlus_BitmapLockBits($bm1, 0, 0, $Bm1W, $Bm1H, $GDIP_ILMREAD, $GDIP_PXF32RGB)
$Stride = DllStructGetData($BitmapData1, "Stride")
$Scan0 = DllStructGetData($BitmapData1, "Scan0")

$ptr1 = $Scan0
$size1 = ($Bm1H - 1) * $Stride + ($Bm1W - 1) * 4


$Bm2W = _GDIPlus_ImageGetWidth($bm2)
$Bm2H = _GDIPlus_ImageGetHeight($bm2)
$BitmapData2 = _GDIPlus_BitmapLockBits($bm2, 0, 0, $Bm2W, $Bm2H, $GDIP_ILMREAD, $GDIP_PXF32RGB)
$Stride = DllStructGetData($BitmapData2, "Stride")
$Scan0 = DllStructGetData($BitmapData2, "Scan0")

$ptr2 = $Scan0
$size2 = ($Bm2H - 1) * $Stride + ($Bm2W - 1) * 4

$smallest = $size1
If $size2 < $smallest Then $smallest = $size2
$call = DllCall("msvcrt.dll", "int:cdecl", "memcmp", "ptr", $ptr1, "ptr", $ptr2, "int", $smallest)



_GDIPlus_BitmapUnlockBits($bm1, $BitmapData1)
_GDIPlus_BitmapUnlockBits($bm2, $BitmapData2)

Return ($call[0]=0)


EndFunc

Tried to do very simple, like If it returns false then declare other variable or smth like that. But how to read return value?

I can see if its true or not with these

iF CompareBitmaps($bm1, $bm2) = False then msgbox(0,"","lol false")

iF CompareBitmaps($bm1, $bm2) = True then msgbox(0,"","lol true")

But how to make to loop throught images?

In primitive way it could be

While 1
;find for smae img
$bm2 = _GDIPlus_ImageLoadFromFile($fname1)

iF CompareBitmaps($bm1, $bm2) = False then
msgbox(0,"","1st one false")
$bm2 = _GDIPlus_ImageLoadFromFile($fname10)
CompareBitmaps($bm1, $bm2)
If CompareBitmaps($bm1, $bm2) = true then MsgBox(0, "bm1==bm2", CompareBitmaps($bm1, $bm2))
Endif
;MsgBox(0, "bm1==bm2", CompareBitmaps($bm1, $bm2))

_GDIPlus_ImageDispose($bm1)
_GDIPlus_ImageDispose($bm2)

WEnd

And I could write this crap in over 50 lines lol
