I appreciate your courtesy anyhow. 
@Everyone
So far, I have been looking into Colour Matrix to meet my goals, however that may or may not be right. Hopefully it is. Hopefully there is a solution. I am dreading having to re-purpose thousands of color object shapes, and trying to come up with a automated 'colour overlay'.  ... so I can make a Red/Green/Blue become totally Blue, or a Rainbow become just Green, by transforming pixels 
I'd be looking forward to seeing what Tic comes up with in his magic labs!  [color]Thanks![/color] |

| Does anybody know how to get a copy of the desktop window, without all the opened windows; in fact, just the wallpaper ? |

I was wondering how it would be possible to load a specific icon from a .ico file using Gdip, instead of loading the first image in the file? It's a bit inconvenient to be only able to see the first (and generally smallest) image!
I tried searching MSDN, but the Gdip API seems very limited...

Look in the registry; I believe the current wallpaper is located in the HKCU root key, Subkey Control Panel\Desktop, either the OriginalWallpaper or the Wallpaper value... |

Yes, I know that
I'd prefer take the wallpaper directly from memory. I can do this with gdi but I'm not able to reproduce it with gdi+  |

tic, I've found another flat API function which may be useful enough to add to gdip.ahk:
| Code: | GpStatus WINGDIPAPI
GdipImageRotateFlip(GpImage *image, RotateFlipType rfType);
|
Corresponds to Image::RotateFlip. |

|
|
Hello,
I think about include the main window of IE4AHK (not the menu, not the tool bar, not the status, only the included content: a web page with its viewer) into Gdip.ahk form , for instance the form#10 of the tutorial.
Is it possible? Is somebody tried to do it in order to design a personal nice browser, without standard window. Something more "graphic".
Elsewhere, is it possible to program the resizing of the window example #10?
I will be very very happy if somebody has these two programs.
Thank for your reply.
Dominique

Hi! Has anyone been able to figure out how to do the colour overlay thing? It seems logical the colour matrix described by Tic is the way to go (maybe not)...but I have tried many combinations of the function. I think I am doing it wrong! I can't get the function to do anything. I don't know why...
Just to re-cap the vision I am hoping for: Re-draw bitmaps into one solid color I specify, while preserving transparency levels. Meaning, basically the complexity of a image is irrelevant. I just want to turn each pixel in a image into a flat single color. |

tic, I'm currently developing a little app that will use your functions.
I just wanted to say thanks for wrapping it up so nicely (one might even say "in AHK spirit"). And also thanks for the very detailed examples (I know next to nothing about GDI+).
Also, your idea of PostMessaging WM_NCLBUTTONDOWN to the title bar to move the GUI is ingenious! |

I have a question. When you want to update the GUI, do you have to redraw everything, or is there a way to only redraw and refresh a portion of the GUI?
Is it efficient to redraw the whole GUI every time when only a small part of it is changing? |

I guess you should redraw all the gui
But you can build the basic layout and store it into a bitmap, then use that bitmap, change what needs to be, and update the gui. It's eating some memory but save cpu time.
It's up to you to choose what you want to sacrifice... |

I see. How would I do that?
It would mean that I would have to copy the original bitmap before using it in SelectObject(), right? So, how do I copy a bitmap?
Sorry for the noobness, lol.
Edit: OK, so the value returned by CreateDIBSection is a pointer to the bitmap. But how do I know the size of the bitmap if I want to copy it to another variable? |

I've done this like that:
| Code: | BGUpdate()
{
; hBG need to be save between redraws to save cpu time
Static hBG
; create the needed stuff as usual
hbm := CreateDIBSection(w, h)
hdc := CreateCompatibleDC()
obm := SelectObject(hdc, hbm)
G := Gdip_GraphicsFromHDC(hdc)
if not hBG {
hBG := Gdip_CreateBitmap(w,h)
pBG := Gdip_GraphicsFromImage(hBG)
; draw the initial stuff onto pBG
; ...
; then delete pBG (as we don't need it anymore)
Gdip_DeleteGraphics(pBG)
}
; draw the previously stored hBG onto G)
Gdip_DrawImage(G, hBG, 0, 0, w, h, 0, 0, w, h)
; draw what need to be added
; ...
UpdateLayeredWindow(hWnd, hdc, x, y, w, h)
; delete the stuff as usual
SelectObject(hdc, obm)
DeleteObject(hbm)
DeleteDC(hdc)
Gdip_DeleteGraphics(G)
}
