Add background color to Canvas _txt : feature request

[Corjan]

Corjan,

Can we please have opacity for..
_fill("red",0.8)

Keith

This already works?

Yep, opacity already works but I don’t think it’s documented on the wiki. Be careful using this though as you also have canvas opacity that will effect the txt. I find it better to put all the txt on a canvas and use opacity on the canvas.

Corjan, Tony,

Correct, not in the wiki.

Tony I am trying to get an annuator to light up. So I want to put a red on top of a yellow.

Any ideas on how to get the best effect?

Keith,

Do you mean a dual colour annunciatior that can be either red or yellow. Also assuming you want to do this with canvas right?

You just need an if else that either draws in red or yellow. I doubt you’ll need opacity. You must call the draw function every time the annunciation state changes so it redraws correctly each time.

Tony,
Correct.
With regards to the annunciator I am doing what you say.
Regarding Opacity, I am using to darken the panel for night vision. So when the sun go's down the MIP gets darker. I use opacity to darken the panel.

Will post a vid clip on what I am doing later today. It is coming along quite nicely.

Oh ok that sounds like a similar method as my panel lighting. I would still use canvas opacity rather than txt though.

Hello Keith

try using a black bitmap overlay with transparency set to 50%
then varying opacity in AM from 0 to 1

Corjan,

Ok the fill works BUT _stroke does not. If I try and add opacity then the thickness of the line changes not the opacity.

Can you please add opacity to _stroke

Keith


EDIT:

The opacity does change BUT when using _arc() there is an issue.

test with this code and you will see what I mean.

Code: Select all

opasw=0.4
		_arc(242, 180,315,317,35)
		_stroke("#CDCDCD",25,opasw)	
		_arc(242, 180,270,272,35)
		_stroke("#CDCDCD",25)

Hi,

Change it into "_stroke("#CDCDCD",opasw,25)" and you should be good.
I'll make sure to add this to the wiki.

Thank you Corjan.
