It don't work for me

My image turns black!

    public override void Render(EffectConfigToken parameters, RenderArgs dstArgs, RenderArgs srcArgs, Rectangle[] rois, int startIndex, int length)
   {
       Bitmap image = new Bitmap(srcArgs.Surface.CreateAliasedBitmap());
       Graphics.FromImage(image);
       for (int i = startIndex; i < length; i++)
       {
           Rectangle rectangle = rois[i];
           for (int j = rectangle.Top; j < rectangle.Bottom; j++)
           {
               for (int k = rectangle.Left; k < rectangle.Right; k++)
               {
                   ColorBgra bgra = dstArgs.Surface[k, j];
                   bgra.R = 0;
                   bgra.G = 0;
                   bgra.B = 0;
                   dstArgs.Surface[k, j] = bgra;
               }
           }
       }
   }

Perhaps the attachment is wrong!

Actually, that's what he intends to happen. It silhouettes images with partial transparency; turns the RGB to 000000 while preserving alpha. (he posted the explanation in Offtopic)

[iRock]

my just turns back

Edit: Nevermind i got it

I've never go to the "off-topic" topic.

Explanations are much better "in-topic" where we can find them with the plugin!

I agree. sabrown, you should post an explanation here. :-)

[Myrddin]

As well as an explanation, perhaps also sample images would be handy?

I would suggest this for all your plugins where you lack screenshots, but as this one has so far had a few people stumped to its use, pushing for samples here would be best.

That's something I do wonder, why don't you have screenshots/examples for your plugins?

I think it's some kind of outline, this is what I got:

I started with this:

Ended with this:

Not sure what it should do?

[david.atwell]

That's what it is supposed to do. Try it with a slightly transparent area.

[Simon Brown]

Try it on a photograph and you will see properly what this plugin is intended to do.

[IceFusion]

O, thanks. I thought I was more or less on the right track.

Sorry - wrong plugin

Update Posted

This should be much faster than the previous version.

[bEPIK]

Thanks for the plugin!

Can this please be moved to the 'Object' menu as it has a few widely used plugins that go into it (so nobody would only have 1 item in the menu). My distort menu, (and I imagine many other peoples) are very cluttered and I think it would fit well into the objects menu as the plugins in that menu need to be used on a layer that has some sort of transparency.

Anybody agree?

[Simon Brown]

I've GPL'd it and released a new version. If someone hasn't by the time I get round to it i'll post a build.

[Aethec]

Am I wrong or is this simply 1 line in CodeLab ? :?

[Simon Brown]

I know, but it was created to fill a need.

Build posted.

[crimsonsorrow]

turns everything i've tried to black. that's it.

[Simon Brown]

It's meant to do that - however, it's only useful when working with images with transparency.
