Gui: Making a specific color fully transparent? Topic is solved

[Scr1pter]

Hi friends,

I created a Gui which consists of a picture that doesn't perform any action.
By doing some researches I was able to find out how to do:
- transparency
- clicking through

The code is this:

Code: Select all

F1::
x := (A_ScreenWidth/2)-(Width/2)
y := (A_ScreenHeight/2)-(Height/2)
Gui +E0x20 -Caption +LastFound +ToolWindow +AlwaysOnTop
WinSet, Transparent, 120
Gui Show, w1000 h1000
Gui, Add, Picture, x0 y0 w1000 h1000, %A_ScriptDir%\pics\Earth.png
return

Esc::
ExitApp

When starting the gui, I can click through it and it looks like this:


My question:
Is it possible that the pink color (0xFF87FF) has a full transparency
while the rest stays at 120?
This is just an example, yet it would be very useful to me
if I know how to filter out colors/making them fully transparent.

I dont have an answer but the edges look very good on the globe

Well I just did it with IrfanView within seconds - nothing special.
As said, it was just a quick test.

Use: WinSet

TransColor
Makes all pixels of the chosen color invisible inside the target window.

WinSet, TransColor, Color , WinTitle, WinText, ExcludeTitle, ExcludeText

Thanks!
This one did the job:

Code: Select all

F1::
x := (A_ScreenWidth/2)-(Width/2)
y := (A_ScreenHeight/2)-(Height/2)
Gui +E0x20 -Caption +LastFound +ToolWindow +AlwaysOnTop
WinSet, TransColor, 0xFF00FF 120

return

Edit:
By the way, I've noticed it's more clever to swap these lines:

Code: Select all

Gui Show, w1000 h1000
Gui, Add, Picture, x0 y0 w1000 h1000, %A_ScriptDir%\pics\Earth.png

Code: Select all

Gui, Add, Picture, x0 y0 w1000 h1000, %A_ScriptDir%\pics\Earth.png
Gui Show, w1000 h1000

By using method 2, you won't see a 1000x1000 square first, you'll directly see the picture.
Makes a better impression.

I have to ask again:
Is there also a way to do the same not just for 1 color but for a range of colors?
I mean pink is not just pink, there are variations.

Or probably two colors.
The first color is 0xFF00FF, the second is: 0xFC62FD (it's pretty similar).

According to this 7 year old thread it's not possible?

You could use gdip and cut out the circle.

Preprocess the image and use your current technique or do it on the fly and use the method in the link.
GDIP can do a lot if you are going to mess with graphics its worth learning to use.
