okay, so here are the scripts (you can delete the old one since these are renamed file names too).
They'll be available under
<Image>/Script-Fu/Path To Darken Layer

<Image>/Script-Fu/Sel To Darken Layer


Note: it's registered under "Sel To Darken Layer" and not "Selection To Darken Layer" (not sure why but when i tried to register it under "Selection To Darken Layer" the script wouldn't get registered)

Hi trandoductin

These two scripts work but the end - step 10 and 11 don't seem to be cropping the layer. I wonder if maybe the crop can be done after, or as part of step two where the selection is already there and has created a the layer already.

2. I create a new white layer.
(set! new-layer (car (gimp-layer-new image width height
RGBA-IMAGE "new white" 100 NORMAL-MODE)))
(gimp-drawable-fill new-layer WHITE-FILL) ;fills background with white
(gimp-image-insert-layer image new-layer 0 0) ;parent 0, insert layer on top position(0)

My bad... I ran into a problem when i forgot to set foreground color as black and thought the script was broken so i commented out step 10 and step 11. And then when selected foreground color as black, the scripts work again but i forgot to uncomment step 10 and step 11.
So here are versions where step 10 and step 11 are uncommented.




PS: would this Height Stretch Selection Script be of any use to you?

Got them...

Yes, now they work good.

I have an idea for a script that would use a little noise, blur and desaturate for smoothing. I may be able to put some info together soon.

Thanks

alright hurray for ideas. can't wait.

I've been playing around with ways of smoothing out gradients, either air brushed or filled, and have come up with a way that seems to work the best.

A script that could give the user a choice to change the Gaussian blur and then followed by two other blur methods that don't need to be set by the user, would be the best. It would go like this.

1. [Filters] [Blur] [Gaussian Blur] with the ability to set it at what you want.
2. [Filters] [Blur] [Pixelize] With the Width and Height set at 3
3. [Filters] [Blur] [Selective Gaussian Blur] with a blur radius of 5 and max delta of 50 (which is the default I believe)

Now the first step would basically smooth out really jagged edges depending on what kind of pixels you have on the image layer, either gradient fills or airbrushed pixels can be very blotchy. But other stuff like lines and details might need less blur. But those other two functions would work very well at the same settings every time. You could just make them editable if you want though. Well just see if you can make them editable by the user.

This whole process works fine on the Darken Only Layers that have the Alpha channel Lock turned on. These are the kind of layers that I would be using it on. No selection is required but it would be able to work on only a selection too. At least it does when I do it manually.

Here it is... I have set the defaults to your described settings for the pixelize blur and selective gaussian blur (but options are there to change it if user chooses to).

Will be available under Script-Fu/Multiple Blurs...

It works on the whole image if there isn't a selection and works on the selection if there is one (this is what it does automatically just like when you're doing it manually).

It works great! I noticed that I need to have at least a 1 for the Guassian Blur (can't have a zero). Otherwise it give an error. I've already given it a keyboard shortcut. This will come in handy.

Thanks, you're pretty good at this script stuff. I appreciate it.

yeah it's weird if you do it manual you can enter for 0.0 for gaussian blur.
But if you do it with script you have to pass in a value > 0.0...should add set the minimum value to 0.1 instead of 0.0?

Oh, yes I will do that.

Oh, I was asking you if i should put 0.1 as the minimum value for the user's input prompt.

Yes I think that would work good. I will be using different values for different kinds of stuff but starting with .1 would be good.

Would I just replace the 5 with a 0.1 in this part of the code: (0.1 0 2000 1 50 1 0)


SF-ADJUSTMENT "Gausian Blur Radius" '(5 0 2000 1 50 1 0)
SF-ADJUSTMENT "Pixelize Blur Width/Height" '(3 0 2000 1 50 0 0)
SF-ADJUSTMENT "Selective Guasian Blur Radius" '(5 0 2000 1 50 2 0)
SF-ADJUSTMENT "Selective Guasian Blur Max. delta" '(50 0 255 1 50 0 0)

nope 1st number is default second number the 0 is minimum (you'll want to change the 0 to 0.1 so that it's
(5 0.1 2000 1 50 1 0)


UPDATE: oh you want it to default to starting with 0.1 then yeah you were right... I just thought to change the minimum too since 0 will give error when run.

I put in (0.1 0.1 2000 1 50 1 0) and it opens first time with 0.1 as the default but if I scroll the arrow down it just goes to 0 anyway and gives error messages.

that's odd it doesn't scroll down to zero for me, it stops at 0.1

I went in a changed the 0.1 back to 5 and it stops now.

Before: (0.1 0.1 2000 1 50 1 0)

Now: (5 0.1 2000 1 50 1 0)

These scripts will change FG and BG colors to default Black and White before running script
then restoring context colors after script is done.

Ah much better. Now I don't have to have the default chosen at the time of using the script.

Thanks,
