Add noise to transparent layer?

Recommended Posts

Hi,

 

I want to use the "Add Noise" effect but have it apply to a transparent layer. In other paint programs, this would just add generated noise pixels to the currently selected layer, but in Paint.NET it appears like it's using the source pixels as input for the noise effect. While visually this effect is pretty on existing image, it doesn't work on transparent layers. Is there a way to just add regular noise to my transparent layer?

What I'm just trying to achieve is generate a television static effect, but have those pixels that were left untouched by the noise effect remain transparent. I need the transparency for use outside of Paint.NET. Is there a way to do this?

Hello Eraesr,

 

Some noise effects work on transparent layers - some don't.

If you would like to try my 'Noise choice' plugin here is the link http://forums.getpaint.net/index.php?/topic/24397-noisechoice/

If you uncheck the 'on object only' button, it will put noise on a transparent layer.

 

Remember to save the layer as a .png to keep the transparency.

 

Hope that helps.

I was going to suggest your plugin, then decided you would probably like to do it yourself :)

 

@Eraesr there are more ways to do it, but ochre's plugin is by far the easiest. Take special notice when he says to save as a .png or some other transparency-supporting filetype. (depending on what you're doing, you might get away with .gif)
