Lately I wanted to make a 3D animation, printing a result of the PrintWindow function in a polygon. So I started from loading an image to check if it works. But it doesn't  . I used GdipDrawImagePointsI here and I believe that this is the problem, because with the GdipDrawImageRectI it works. What am I missing? I'm posting the code:
| Code: | #WinActivateForce
Gui, +LastFound -Caption +Owner +AlwaysOnTop +E0x80000
; -0x20 -E0x80 +Disable
AddImage("test.png",WinExist(),W,H)
Gui, Show, w200 h200, Experiment
AddImage(sFile,hGui,ByRef Width="",ByRef Height="",pBits="")

You'll need an image called test.png in the scripts directory. |
