Some Graphical Examples using GDI+ Vol. I

Recommended Posts

@monoceres: thanks for feedback -> changed it to sleep(20)

Apropos sleep - it's a good idea now -> Goto Sleep(6h) :)

Nice effect. :)

Playing with transparency gives an interesting variation too:

Wow I really need to start learnin GDI+. I'm wondering, is there a way for this to run in the background and export the image as a jpeg?

Yes. You can search examples in the forum like the captcha (can't remember the author). Edited by Josbe

Wow I really need to start learnin GDI+. I'm wondering, is there a way for this to run in the background and export the image as a jpeg?

Yes and very easy too.

Since UEZ is double buffering the with a standard bitmap you can replace the following line:

_GDIPlus_GraphicsDrawImageRect($Graphic, $ParticleBitmap, 0, 0, $width, $height) ;copy to bitmap

with:

_GDIPlus_ImageSaveToFile($ParticleBitmap,@ScriptDir&"\"&$LoopCount&".jpg"

where $LoopCount is an integer that you increment every loop.

I don't know why Barbarella is in my head when looking this. And Jane Fonda.

Very nice!

Strange fantasy :) LOL :o

Naw, this is a start to a possible 3D game. I need to do more with that. I've been slacking lately. http://www.autoitscript.com/forum/index.ph...;hl=au3irrlicht

Edit, the reason I was asking about exporting the image was possibly adding that to my 3D work, having a spinning cube with the pearl necklace on it, that would be nifty.

In my opinion the problem is not GDI+ but the mathematics to realize 3D :)

I'm just a beginner, too.

looks like a good base for building a "3D" game (the squares script) :o

great work btw! :):D

      capture content of scrollable window/control capture cascaded menus Due to DllCall("User32.dll", "int", "PrintWindow", "hwnd", $hWnd, "handle", $hMemDC, "int", 0) limitation some windows cannot be captured properly (GDI+, ProgDVB, etc.) but can take screenshots of hidden windows. One workaround is to use full screen capturing (F11/F12) or "Grab Screen" function! Or try double click with rmb on listview items (beta).
      Download source code (8885 downloads previously): AutoIt Windows Screenshooter v1.83 Build 2019-06-14.7z (version 3.3.12.0+ needed!)

      When 'Grab Screen' is clicked you can hold down the ctrl key to switch to 'grab controls' mode. Control under mouse will be framed red.
      ctrl + shift will take the screenshot of appropriate control. To capture GUI menus you can press rmb which simulates the lmb. When a menu is opened press shift additionally to capture it.
      Press and hold only the shift key to capture any region on the desktop using freehand capturing - release it so capture marked regions!
      Or just mark resize able area which you want to grab. Press CTRL key to grab marked area or right mouse button to capture the marked area every x seconds for a duration of y seconds.

      Just press the lmb and move your mouse. When lmb is released you can adjust the size of the window by dragging the white rectangle to any direction. Rmb will move the marked area.
      Press ESC to get the coordinates of the marked region.
      If you have any improvements, please post it here.
