I am proud to announce an UDF collection for FreeImage.

The Library contains all functions of the 3.15.0.0-release (the documentaition is located here (PDF) )

If you need more informatin about the functions, you have to read the PDF since i did not include comments in the AU3-file.

If you want to download it, click here: [uDF] FreeImage library Downloads:Posted Image

And now an example for resizing an image (it saves the resized image in a new file, e.g. image.png will be saved as image_rsz.png)

#include <FreeImage.au3>

_FreeImage_LoadDLL(@ScriptDir&"\FreeImage.dll")
_FreeImage_Initialise()

$sFile = "800x600.jpg"
; new sizes
$width = 400
$height = 300

$FIF = _FreeImage_GetFileTypeU($sFile)
If $FIF = $FIF_UNKNOWN Then
    $FIF = _FreeImage_GetFIFFromFilenameU($sFile)
EndIf
$hImage = _FreeImage_LoadU($FIF, $sFile)

$hImageResized = _FreeImage_Rescale($hImage, $width, $height, $FILTER_LANCZOS3)
$dot = StringInStr($sFile,".",1,-1)
$Name = StringLeft($sFile,$dot-1)
$Ext = StringMid($sFile,$dot)
_FreeImage_SaveU($FIF, $hImageResized, $Name &"_rsz"&$Ext)
_FreeImage_Unload($hImage)
_FreeImage_Unload($hImageResized)

_FreeImage_DeInitialise()
</div>

And an other example for Flip and Rotate:

#include <FreeImage.au3>

Global $ImageHandle=-1, $WorkingFileName, $FIF

_FreeImage_LoadDLL(@ScriptDir&"\FreeImage.dll")
_FreeImage_Initialise()

Func OnAutoItExit()
    If $ImageHandle <>-1 Then _FreeImage_Unload($ImageHandle)
    _FreeImage_DeInitialise()
EndFunc

GUICreate("FreeImage Test GUI",800,700)
$ShowPic = GUICtrlCreatePic("",0,0, 800,600)

$btnOpen = GUICtrlCreateButton("Choose File", 10, 610, 100, 30)
GUICtrlSetTip(-1,"Only a copy of the image will be used")

$btnFlipH = GUICtrlCreateButton("Flip Horizontal", 120, 610, 100, 30)
$btnFlipV = GUICtrlCreateButton("Flip Vertical", 230, 610, 100, 30)
$btnRotate = GUICtrlCreateButton("Rotate ...", 340, 610, 100, 30)

GUISetState()

While 1
    Switch GUIGetMsg()
        Case -3
            Exit
        Case $btnOpen
            _OpenImage()
        Case $btnFlipH
            If $ImageHandle <> -1 Then
                _FreeImage_FlipHorizontal($ImageHandle)
                _FreeImage_SaveU($FIF, $ImageHandle, $WorkingFileName)
                _ShowImage()
            EndIf
        Case $btnFlipV
            If $ImageHandle <> -1 Then
                _FreeImage_FlipVertical($ImageHandle)
                _FreeImage_SaveU($FIF, $ImageHandle, $WorkingFileName)
                _ShowImage()
            EndIf
        Case $btnRotate
            If $ImageHandle <> -1 Then
                $hImageNew = _FreeImage_RotateClassic($ImageHandle, Number(InputBox("Rotate", "angle for rotation", 90)))
                _FreeImage_SaveU($FIF, $hImageNew, $WorkingFileName)
                _FreeImage_Unload($ImageHandle)
                $ImageHandle = $hImageNew
                _ShowImage()
            EndIf
    EndSwitch
WEnd

Func _OpenImage()
    Local $sFile = FileOpenDialog("Choose Image","", "Image Files (*.jpg;*.jpeg;*.bmp;*.gif)", 3)
    If @error Then Return
    If $ImageHandle <> -1 Then _FreeImage_Unload($ImageHandle)
    Local $dot = StringInStr($sFile,".",1,-1)
    Local $Name = StringLeft($sFile,$dot-1)
    Local $Ext = StringMid($sFile,$dot)
    $WorkingFileName = $Name &"_FI4AU3"&$Ext
    FileCopy($sFile,$WorkingFileName)
    $FIF = _FreeImage_GetFileTypeU($WorkingFileName)
    If $FIF = $FIF_UNKNOWN Then
        $FIF = _FreeImage_GetFIFFromFilenameU($WorkingFileName)
    EndIf
    $ImageHandle = _FreeImage_LoadU($FIF, $sFile)
    _ShowImage()
EndFunc

Func _ShowImage()
    Local $Width, $Height
    _SizeProportional($Width, $Height, 800, 600, _FreeImage_GetWidth($ImageHandle), _FreeImage_GetHeight($ImageHandle))
    GUICtrlSetPos($ShowPic,0,0,$Width, $Height)
    GUICtrlSetImage($ShowPic, $WorkingFileName)
EndFunc






Func _SizeProportional(ByRef $Width, ByRef $Height, $WDesired, $HDesired, $WSrc, $HSrc)
    ; Prog@ndy
    Local $RatioDes = ($WDesired / $HDesired)
    Local $CurrentRatio = ($WSrc / $HSrc)

    If $CurrentRatio > $RatioDes Then ; scale height
        $Width = $WDesired
        $Height = $WDesired / $CurrentRatio
    Else ; scale width
        $Width = $HDesired * $CurrentRatio
        $Height = $HDesired
    EndIf

EndFunc   ;==>_SizeProportional

Corrected... forgot to rename it. That happens when you copy / paste functions 40 times in a row...

I tried to download, the other day, for about dozen times and failed every time. :party:

edit: It's happening again. I just can't download. It starts and then DL slows down to 0 after few seconds. :)

We all get this with lots of lookie-loos around here.

I used your demo and it worked fine. However, when I read some of the abilities of the dll, like rotations and etc, I thought maybe you should have given a better demo that displayed some of the capabilities of your UDF.

Nice job overall, just don't understand all the applications.

Yeah, i didn't have time to write a good example. I'm thinking about a GUI with some Buttons :)

@trancexx: I'll send you a PN with the Library. I'm sorry, but i doN#t know the reason why it is not working for you.

Nice work Progandy... certainly is a hog on the cpu during the calling sequences though.

Huge and nice work ProgAndy (as always :party: ).

...so, imagine the size of the heads of creators of FreeImage.dll. :)

One more thing. I see this thread is rated 3 and three peoples voted. Yashied gave 5. So, other two forum members rated it with 4 or 3 (together!!!). Either sick or by accident. In any case - stupid.

I believe that ProgAndy has done the hard work, and the result of the work exceeded all my expectations. This is definitely 5+. If someone does not understand how to use a library or do not want to understand, this is not the reason for the reduction of rating. This is not an objective opinion. This UDF will facilitate the work with images to many people. If you look at the counter, then the library has been downloaded 108 times during the 4 :) days. This speaks to the interest of people to this work. I do not understand what reasons people rated it at 3* or 4*. Maybe they will tell us about it?

ProgAndy, 5 stars that I have promised.

Good work man, was actually thinking of a similar UDF a couple of weeks ago but never got to it :)

Huge and nice work ProgAndy (as always :idea: ).

Thank you all :party:

@ProgAndy

Nice work as usual.

If some feels better off with the COM version, you can download the wrapper here.

Including the Help file and Example application.
