I don't speak Klingon, but I do speak Gringo.See haa-blah ess-pan-ol'.

Going through this frequency thing is going to take a bit of time. That is, I need to think things through a bit more and organize. Maybe my brain will work on this while I'm sleeping. Yes, sometimes I dream in techno-babble.

For now, check this out:
Code:
OnFilterstart:{
	//Info("isTileable %d",isTileable);
	isTileable=0;
	setZoom(1);
	return false;
}
See the setZoom? It is set to 1 and that means preview at 100% no matter what you do because it is in the OFS structure. If you use scaleFactor like I showed eariler, you can comment out setZoom() in OFS. The preview won't be entirely accurate when you zoom out, but it will be close enough.

If you want to see something really cool, change:
Code:
isTileable=0;
to
Code:
isTilable=True;
What you see when you click Okay will be *very* relevant.

Adaptive Equalization by Reindeer is one of my favorites. I've used it in the past very successfully for some forensic things.

So now your a mind reader too?
I was going to ask about that last night, but the clock keeps whizzing round too fast.

Seems that any filter that depends on a slider with some measure in pixels, requires some trickery to get the preview accurate - or, otherwise, best just to clamp the preview to 100%.

If I understand this right, unless you take the necessary precautions the preview can be completely different to the applied filter.

If I am still understanding right then the precaution would be to scale everything up / down for the preview with the scaleFactor.

(let's go slow, I'm still waking up)

You got it, Roland. You can easily test this with the border code that Ken posted. If you got the yarbles for it, fix it with scaleFactor.

Let's see, the series goes something like this:

setZoom(1) = scaleFactor of 1 = 100%/1 = 100%
setZoom(2) = scaleFacotr of 2 = 100%/2 = 50%
setZoom(3) = scaleFactor of 3 = 100%/3 = 33%
setZoom(4) = scaleFactor of 4 = 100%/4 = 25%

All the way to 16, I believe.

Jeez, Roland, looks like you nailed it. I ran it through some paces and it seems to be a bit of alright. Way to steal some of my thunder. Kudos.

Now, deGrunge can already be done with stock tools. Can also be done with Lum Frequencies. But it sure feels good doing it your own way, eh? It's all your own nuts-n-bolts. Can you feel it? Can you?

Tomorrow I'll start back on my HsY thing. Hopefully soon you'll see some real goodness come of it. After that, I'm planning on some other convolution stuff.

Of course, I'll do my best to field any questions that come up regarding whatever.

Well Done Rô
That was quick. And it works great. Your C knowledge obviously helped a lot.
Are you going to make it seven band?

I know exactly what Stroker means. I can almost see the pixels whizzing through the code.
That’s why I prefer to leave them as ffp files rather than 8bf files,

Stroker it Sounds like you have another genius in the family. Are you going to teach her Photoshop next?

The documentation always seems to stop just short of what I need. There's a whole load of things to discover, but it's an uphill struggle.
Maybe I'll put a list of questions together and see if Stroker can fill me in.

Yeah, but if it was easy it wouldn't be fun. Would it?

Trying to download

What am I missing here? I am trying to download the filter in the zip file and all I get is an attachment.php that says I am not registered. Are there some restrictions or something that I am not aware of?
