Basic Slideshow Wallpaper (Multiple Monitor)

Recommended Posts

While looking for a way to change my desktop background of only my secondary monitor, I found a few simple solutions that are built into Windows. But when you look up how to do such with a slideshow... You only find programs that cost money. So, I set out to make it myself.
This is a pretty basic program. It simply displays an image in the center of the screen (scaled to fit screen) and uses a black background.
The program does allow mouse passthrough, though you can't drag and drop over it, so it wouldn't really work well if you have icons on your second monitor.

      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.

      This is a project that I have been working on for several months off and on.
      It's a simple "What You Hear" MP3 @ 320Kbps and WAV audio recorder.
      Features:
      - LoudMax, a Gain Controller and Look-Ahead Limiter
      - Auto Shut-Off after one minute of silence
      - Side-by-Side Simulated LED Meter
      - Running Time Counter
      It started off being a large project, but I eventually stripped it down to its
      bare essentials because I came to realize that it would be very difficult to
      deal with every sound card and every way a PC is set up for audio. It would
      have been a nightmare that I was not willing to go through.
      This project contains the most up-to-date BASS.dll v.2.4.15.0 - December 17, 2019.
      All BASS Dll's are 32bit. Those and the needed UDF's are included in the zip file.
      I will try to explain how it works in the next post.

      I have been working on audio graphical scripts these last several months.
      This is my last script on this subject for now. On to other projects.
      Credits: UEZ, Eukalyptus, BrettF, Prog@ndy, Authenticity and the AutoIt Community.
      Thanks to all that made these scripts possible!
      Please let me know if you have any problems with it.

      I have been playing with this script off and on for about a month - trying to get the needles to look more realistic.
      It's best to use with an audio limiter on the source audio, or else you'll be tweaking the input levels on every song.
      It should work with any version of AutoIt, starting with 3.3.8.1.
      Please report any problems with it. Credits are in the script.

      How can you select the specific style of a font with multiple * .otf files?
      The font in question has several files:
       
      Thin Thin Italic Extra-Light Extra-Light Italic Light Light Italic Regular Regular Italic Medium Medium Italic Semi-Bold Semi-Bold Italic Bold Bold Italic Extra-Bold Extra-Bold Italic Black Black Italic But after doing several tests I can recall the font like this, without being able to specify the precise style:
      Local $hFamily = _GDIPlus_FontFamilyCreate("Poppins") ; Local $hFont = _GDIPlus_FontCreate($hFamily, 95, 1+2, 3) ; Example I cannot therefore select "Poppins Black Italic"
      but only "Poppins" 
      Thank you
