Valentines Hearts

Recommended Posts


Credit's go to @UEZ for his post from 5 years ago for the GDI+ Heart!

Really, I was just bored... I didn't have a valentine (:'( )so I whipped this up in a couple of hours. Pretty sure I cleaned up all my resources properly but it's late and I'm tired.

$HAPPY_VALENTINES is the string that is shown in the middle of the screen

$MAX_HEART_COUNT controls how many hearts are displayed

When you first run it it will display a tooltip with the % of the string drawn (since it needs to drawn line by line). The larger the heart, the longer it'll take to draw it. Once it's been drawn once it's saved (@TempDir & "\heart.png") and will be reloaded on each startup. It will check to make sure that the heart saved is the size in the current script. If the sizes don't match it deletes the old saved heart and redraws the correct size. (I.e., if the heart saved is 350px wide and the $MAX_HEART_SIZE is 250, it deletes the old heart.png and remakes it the correct size)

Most of it should be pretty self explanatory. There's a lot of comments too.

And since I like to see pictures of the code people post, here's mine! (The script is animated, my picture is not ;))



Edit: Moved the Drawn string and rectangle outside the for loop for each heart. Increased FPS dramatically! Lol Also included the .ico and .exe

Edited post, moved the drawn string and rectangle outside my big for loop. That increased fps dramatically. Also included .ico and .exe in original post.

      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!

I only want the edit box to be partially transparent.
      Help appreciated.

      I am searching for a way to display a transparent image (or Icon) over an Button. And the image should always stay on top.

      Here is what i have so far:
      At script start the picture is over the button..but if you move the mouse over the button it overlaps the image.
      And if i add $GUI_ONTOP to the picture, the transparency is gone

      Maybe someone has an idea..

      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:

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].
