Help with two _GDIPlus_ImageGetGraphicsContext to one _GDIPlus_GraphicsCreateFromHWND

[Luigi]

Hi, I try draw diferents buffers in the same Gui, without manipulate it like one big handler (or unique), but, divide it in little handlers and control each one in diferent way.

The idea is a window with normal controls (GUICtrlCrateButton and similars) and with two or more _GDIPlus_ImageGetGraphicsContext...

I search in the forum and found wonderful exemples (but very complex to me at this moment), I cant see 'where' are correct form to write this two controls/handlers.

I will try many times, but does not work... I need help to draw pics/handlers.

Thanks.

I can write this. Is the best way to write 3 or more BackBuffers in one Gui?

What do you want to achieve using 3 different graphics context handles? The only reason I can see is when you want to rotate each objects.

This is what you asked for?

@UEZ, I am new with GDIPlus and try many things, but this moment I want build a little image editor, like this below. Need write a zoom tool... perhaps another time.

Maybe I thinking wrong, but is not all graphics context handles is updated every time, this is a reason to break a big control in small controls, or this is not necessary? Thanks for your reply.

@Andreik, realy thank you for your reply, but not is this I want. Thanks.

This script is not ready, still a draft, but is half functional.
