UEZ, i thought more to the pixel definition of the photo...

Do you think, it will be displayed with same quality when zoom will be used ?

Look here what I mean:

UEZ, I have modified script for work with a smaller photo as you said and you're right, window is not jerky,

but as you can see, zoom on my son return a very bad quality ! 

This is well what I feared 

First photo with  v1.0.3.0 and 2nd with v1.0.3.1

I haven't tried this at all... but would it be possible to re-render the preview photo at a higher resolution only when you use the zoom feature? Or would that cause a lot of lag / delay?

Problem is that photo is LoadFromFile with gdi function when photo is dragged on gui...

I can't divine what will be user's actions.

Would it be possible to load the image into memory, then work on copies of it, so you can keep the original full res version available for zooming, etc? It might not be, depending on your app's design.

[UEZ]

wakillon,

you can add this to line 473

DllCall($ghGDIPDll, "uint", "GdipSetInterpolationMode", "handle", $hGraphic2, "int", 7)

to increase the quality. I would recommend that you use a larger preview dimension without impacting GUI repaint speed but not largen than 800x600.

Or as wraithdu suggested scale down from original image only when zooming.

I didn't see a real difference with GdipSetInterpolationMode added...

Try with this changes in the _GuiGetDroppedFilePath function where previewer is set to 570x570 px.

Local $iNewWidth, $iNewHeight
        If $iPicWidth > $iPicHeight Then
            $iNewWidth = $iPolaPicSize*2 * $iPicWidth/$iPicHeight
            $iNewHeight = $iPolaPicSize*2
        ElseIf $iPicHeight > $iPicWidth Then
            $iNewWidth = $iPolaPicSize*2
            $iNewHeight = $iPolaPicSize*2 * $iPicHeight/$iPicWidth
        ElseIf $iPicHeight = $iPicWidth Then
            $iNewWidth = $iPolaPicSize*2
            $iNewHeight = $iPolaPicSize*2
        EndIf

It's a bit better, no ? 

[UEZ]

Change 7 to 5 to see a real difference.

 

This works with a proper speed on my system:

Local $iNewWidth, $iNewHeight, $fFactor = 2.25
        If $iPicWidth > $iPicHeight Then
            $iNewWidth = $iPolaPicSize*$fFactor * $iPicWidth/$iPicHeight
            $iNewHeight = $iPolaPicSize*$fFactor
        ElseIf $iPicHeight > $iPicWidth Then
            $iNewWidth = $iPolaPicSize*$fFactor
            $iNewHeight = $iPolaPicSize*$fFactor * $iPicHeight/$iPicWidth
        ElseIf $iPicHeight = $iPicWidth Then
            $iNewWidth = $iPolaPicSize*$fFactor
            $iNewHeight = $iPolaPicSize*$fFactor
        EndIf

Ok, it gives a good compromise between quality and ease of use.

Thanks for your help UEZ !

I suppose you use google translate...try with http://www.bing.com/translator/

[UEZ]

Yes, because my french is even worse than google translate

What is the correct translation for "Your are welcome / Bitte schön"?

Je vous en prie. Or like ordinary normal working plain people would say - de rien.

[UEZ]

Merci trancexx.

...So I was taught. Don't take my word for it.

I'm much better with Portuguese.

 Yes both salutation answers are good.

In some cases you could add "tout le plaisir est pour moi !" or "ce fut un plaisir !"

Je tenais a vous remercier tous les deux pour votre aide.

C'est cool de tomber sur des personnes a la fois compétentes et sympas !

Cordialement.
