Display an animated picture / vidéo with alpha.

[Guest]

Hello everyone,

Does anyone knows if I can display an animated picture with an alpha layer in a dialog / display ?

If not I will take a look myself. This thread is just for helping me saving some time and tell people if that kind of thing is possible.

Thanks.

I don't think you understood the question. It's not how but does it work. I want to know if I can display an animated gif for exemple.

In the vanilla game there are some animations which are done by creating a series of RscPictures with each animation frame as their texture. And then some script goes through them with ctrlShow. (I guess. Haven't seen the actual related scripts.)

Or you could create just one control and change its texture with ctrlSetText.

Yeah so I need a frame by frame thing... I'm disapointed there is no "video" format allowed in Arma. I will have to compress the .jpg to have the smallest size possible.

It would be definitively easier to support a video format.

JPEG doesn't support alpha either, right?

 

You can play normal opaque videos in .ogv format.

Yeah just remembered that. I will need to use paa or tga sadly.

Thanks for the help I will take a look at that.

class RscTitles {
	class TopHud: RscText
	{
		idd = 1100;
		duration = 1e+1000;
		movingEnable = 0;
		fadein = 0;
		fadeout = 0;
		name = "TopHud";
		controls[] = {
			TopHud_2
		};

		class TopHud_2: RscPicture
		{
			idc = 1101;
			x = 0.381406 * safezoneW + safezoneX;
			y = 0.016 * safezoneH + safezoneY;
			w = 0.5;
			h = 0.5;
			colorBackground[] = {-1,-1,-1,-1};
			text = "20.paa";
		};
	};
};

colorBackground[] = {-1,-1,-1,-1};

Should this be 0,0,0,0 for transparent background?

Nope, it does not work

Yeah, you're right. It wasn't that.

 

I tried your class definitions and the image was transparent as it should. So I guess your .paa is faulty? Recheck it with TexView to see if the background is transparent.
