First of all, this is my very FIRST attempt to actually try to accommodate myself with an existing script, namely the recent charcoal.scm (which me and Rod asked for leaving the original layer and working on a copy at the Registry). I'm sort of glad the author showed indifference because I knew eventually it would push me into trying harder to do it myself. So I did. Took me several hours, but I figured it out.

This script now gives you the ability to leave the original layer (tick new layer toggle) and to max the original layer to the new image size (tick Max original layer toggle) should you tick the Resize for optimum effect toggle.

I've added Saulgoode's suggestion to the script and resubmitted the zipped file. It will no longer require the extend layer script to work.

The Max Original toggle calls up Saulgoode's sg-extend-layer.scm script, so grab that if you don't have it.

Lovely, thanks mahvin.



I think if i were to select all the black in several dif layers i could color it nicely.

Do you maybe knows what the script does?
i may see the effect, i mean do you know how does that, which steps automatize ?

I like having the original image preserved. Nice job, mahvin.

great on the tiger !

I like this Mahvin. Thanks

It appears that whenever your version of the charcoal script calls the Extend Layer script, there is no selection present. If this assessment is accurate, it would be quite easy for your script to rescale the layer by itself, without calling Extend Layer (if there is no selection when Extend Layer is called, the script merely scales the entire layer to match the image size).

Saulgoode:

Couldn't you then tell it to unselect the image before scaling? I mean, I looked at different ways to make it scale, but wasn't sure what was involved in the procedures. But I knew your script performed the task. So, if I wanted to remove all selections first, then perform the code you have above, would that need to include:

(gimp-selection-none image) - ?

I may have missed something, but from my cursory examination of the (charcoal) script, there doesn't seem to be a selection active* at the time you perform your scaling. Performing a 'gimp-selection-none' would not hurt anything, but I didn't think it necessary (and if it were necessary then I should feel compelled to re-examine my understanding of what is supposed to happen).


* The preceding operations entail a Select By Color, followed by copy and paste. When the paste occurs (creating a floated selection layer), there is no longer any selection present (even though the display may show marching ants around the original selection), and there is still no selection present after this floated layer is anchored.

When I can, I will try it out! I like the results! If you keep your original color layer, you can experiment with blend modes and see what sweet images you get!

Saulgoode:

I was just asking in the scope of how scripts work. The script already removes all selections at the beginning, and I followed the procedures to make sense of how it laid out before I called up your script. I guess I should have experimented with the various procedures before taking the lazy approach.

The procedure database isn't really all that explanatory in its usage and debugging bad syntax in the console isn't entirely helpful, either. If someone wrote a book on Scheme (GIMP script-fu) I'd buy it, even though I know it helps to look at existing scripts to make sense of what does what.

I had to turn off the resizing, because I was getting some weird results. When I did this image, I merged all the non original layers and placed it above the original image. I set the blend mode to value. I really loved the effect. Then I took it one step further by selecting the darker part of the sky and filling it with white on a new transparent layer between the other two.

The original image is my own, by the way.

PM: I've run this script in every possible imaginable way and it works out just fine in every instance. The only thing that I can possibly envision being a problem is the merging layers being commented out. I can't reproduce any "weird" effects, as you experience.

Even if I turn off resize for optimum effect and turn on Maximize original layer, still runs fine.

Which version are you using, btw?

I've run across a problem if NO toggles are true. The script then does NOTHING. Hmmm, default should be the charcoal script still runs. I'm not seeing that happen.

It could be something flakey with the dinosaur computer I am trying it on.

PM: Ok. I want the script to do what it's suppose to do. Unfortunately, in all my testing, suddenly Saulgoode's recommended changes stopped extending the layer, even though I did nothing new to the script (just turned toggles off and on).

So, I reverted back to my calling his extend layer script and it works again. Thankfully.

that saulgoode script has a very different effect if there is or not a selection on the image

As behaviour it is very logic but for me was unexpected...maybe you want try to run on 2 copy of the same layer to extend, once with nothing selected
the second for example selecting all the layer ,shrinking selection of 1 px from the border

Yes, I could do that, but I want the script to work out of the box for everyone, without them having to deal with these issues.

I haven't tested your suggestion, but I will try it and see if it changes anything for this input:



Right now I reverted back to the following because after playing with the toggles on the script (in usage, not in edit mode) it somehow "broke" his above recommendation:

Hy i didn't intend to say that you need to modify something in the charcoal script about selection

my point was that the sg script you call does something very different if there is a selection or not

...basically i was suggesting only to try the saulgoode script with and without selection just to check its peculiarity

PC: I am aware of that. I was just stating that I want the script to work without the user having to do something to make it happen. But I am all for testing. One way for me to learn.

Try this code instead:
