Run the scripts in TestMode by pressing F5 in SciTE

Or compile them by pressing F7 and select the Screensaver in the Windows-Screensaver Settings

 

The Direct2D-UDF in the download file is not the latest one - you find the newest version in my signature:

      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.
       
      Tested on Win10 x64 only.

      Hi Community,

      I'm looking for a way to do a Video Overlay GUI or something like that. The idea is to create a GUI which plays a video loop (with transparency/alpha channel) in front of an other GUI. Before you asking why - because I don't believe that GDIPlus can do it out of the box. My skillset for that kind of graphical things isn't good enough to do that, but here are some specialist like @UEZ maybe who can help.

      Example alpha channel video (visualized as animated *.gif):

      I tried to do the light rays effect directly with GDIPlus, but honestly that's a bit too difficult for me. I would be very glad and grateful if there are some suggestions, ideas or recommendations.

      Code for the Video play:
       
      Example video "End.mpeg":
       
      The next challenge is that the overlay GUI should be not clickable. If I hover over the overlay area, I want to have the possibility to control the GUI or what ever, in the background. But if there is any chance to make it with GDIPlus as a Video Overlay for light rays, I would prefer that approach instead of my crazy work-around idea.

      Thanks for any suggestion - I'm grateful!

      Hello i am new here and this is my first thread
      in this script i used some code snippets from forum.
      I do not remember who these belonged to.
      Disabled
      ALT+F4
      ALT+TAB
      TASK MANAGER
      LOCKING WINDOWS
      deleted items from ctrl+alt+delete screen
      (Lock Computer,Switch User,Sign Out,Chance a password,Task Manager)
       
      CTRL+ALT+DELETE (how ?)
      firstly we are disabled locking computer
      RegWrite('HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System', 'DisableLockWorkstation',"REG_DWORD",0x00000001) and then ctrl+alt+delete pressed IsDesktopLocked() triggered.
      we are calling  
      Run("rundll32.exe user32.dll,LockWorkStation") command with checking if $blockctrlaltdel = 1 statements. 
      then it return us to kiosk screen, because we are disabled locking computer.

      I had thought that _GDIPlus_ImageClone($hImage) removes all property items, but I now know that it copies property items.
      What is the easiest way of copying an image that has property items to another image that does not have property items?
    • c.haslam
      By c.haslam
      I think that _GDIPlus_ImageGetPropertyItem should return a Property Item that can readily be set as a property of another image. Why would one want to do this? A script might (as one of mine does) edit an image of a .jpg file then write the result to a .jpg file. In editing it, in my case, the number of horizontal and vertical pixels change, and the date/time edited should be set as a property. All other property items remain the same. Other GDI+ users may change other properties.
      So an approach is to copy all the property items from image1 to image2, then update a few properties.
      M$ provides a Property Item class (id, length, pointer to an array of values) but _GDIPlus_ImageGetPropertyItem returns something different.
      I think that, wherever reasonable, UDFs that are wrappers for M$ methods should work like M$'s methods. _GDIPlus_ImageGetPropertyItem does not do this:
      While M$ returns 2 values for a value that is a ratio of 2 numbers,  _GDIPlus_ImageGetPropertyItem returns numerator/denominator as a single value (often a Double). _GDIPlus_ImageSetPropertyItem (when included in GDIPlus.au3) will be unable to set ratio property items properly because it cannot know what the numerator and denominator are. So copying such property items will not work properly. M$ has a Void* buffer where the buffer is an array of values but _GDIPlus_ImageGetPropertyItem() returns the values in the same 1-d array as id, length and type. M$'s approach produces a 1-d array with the same number of elements for all property items while _GDIPlus_ImageGetPropertyItem produces a 1-d array with various numbers of elements. To me, this is not good programming practice. For a photo from a Sony camera, the worst case has 1-d array with 67 elements. When combined into a 2-d array with the property items of all properties, there are 66 rows and 67 columns, with many elements not used. So I suggest that _GDIPlus_ImageGetPropertyItem look like this:

      #include <GDIPlus.au3> #include <Array.au3> Example() Func Example() _GDIPlus_Startup() Local $hImage = _GDIPlus_ImageLoadFromFile(RegRead((@AutoItX64 = True ?

I have tested this code by updating and adding property items to torus.jpg and to a photo taken by a Sony camera. The code for implementing and calling _GDIPlus_ImageSetPropertyItem will be fairly simple [see below].
