GDIPlus PNG Manipulation - not sure how to...

[Kovacic]

Hi all.. I am not all that good with GDIPlus, but it seems that is what I need to use to do what I need to do. 

This application will be a simple wizard type application with panels. There will be 6 panels total, and I have included a generic image for each to show the example. I am using GDIPLus to put PNGs on top of PNGs. I am stuck at 2 things

I would like to be able to create a mouse over effect for each button. I don't care much what it is, only I would like something to happen, like a 1.2 zoom, or a color shift of the button.
I would like to show, and hide panels / buttons depending on what step the user is on which will be defined by a variable, or by a simple function.
I cant get either one to work and have over 8 hours invested in designing and testing, and I can't do this for the life of me. If anyone can throw me a hint or a line of code, or even breadcrumbs to the right direction, it would make my December.

Most of the influence for the code is here: https://www.autoitscript.com/autoit3/docs/libfunctions/_GDIPlus_GraphicsResetTransform.htm

Here is the attached code and sample images... The backgrounds contain the places where the buttons should be..

To get your script run properly I would suggest to put the images with its original names into one zip archive and uplaod the zip archive here.

Update to the code... I can now selectively switch panels, and show images as needed.. I just need to be able to create a button for an imaged called int he following example:

 

This control somehow needs to act like a button..

Global $ddd = _GDIPlus_ImageLoadFromFile(@ScriptDir & "\" & $GoBack)
            Global $ddd2 = _GDIPlus_GraphicsCreateFromHWND($hGUI)
            Global $ThePicGoBack = _GDIPlus_GraphicsDrawImage($ddd2, $ddd, 7.68, 391.68)

(ignore the globals, I will clean them up later)

 

All code so far:
