Attached is a zip file containing the original XCF images that I used for producing not only the results illustrated as examples in my opening post, but also those, if any, shown in all other posts of mine in this thread.
Each XCF file is placed in a separate subdirectory that also contains two screenshots: one of the illustration itself and one of the dialog box showing the appropriate settings to get the particular sequence of layers related to the specific example.
I hope this will be useful for you to understand even better how the script works.

@ Graechan: nice example of duplication! You have perfectly interpreted the real scope of my script.

@ PhotoComix: grazie a te per l'apprezzamento.

That's very good of you Gino D. I think your script is great and the documentation for Multi-Replicate at GIMP Plugin Registry is also very well done

in agree with Odinbc, the documentation is very good !

any chance we can have it as a pdf ?

Here's a PDF copy of the Multi-Replicate info page at the Gimp Plugin Registry.

excellent Odinbc !!!

Thank you, Gino! I appreciate your help.

@other guys. I've never said that documentation was poorly written or I don't understand the meaning of script's main functions.
They are, in fact, more simple to understand than, for example, a similar tool in Inkscape - Tiled Clones Tool.

The script just did not produce what I'd expected, then it was producing the same image regardless of settings, on the third attempt it crashed GIMP.
That might have occurred because I gave the script a hard time changing settings back and forth so many times.
That's the only reason I asked Gino about script's exact settings to reproduce the images in the opening post.
As for the script itself, I think Gino has done a great job and I do always appreciate complex software.

well obviously Graechan, they were in such a hurry they even left their cute little bear house shoes on

As some of you might have noticed, I tried to make the documentation at the GIMP Plugin Registry as similar as possible to the layout used on the official GIMP online documentation. I also thought that a script fitted with such an amount of settings of course would have needed to be accompanied by a detailed explanation, so that's the reason why (sorry!) I have been a bit wordy.



Odinbc: thanks a lot for converting it to PDF format. Well done, the file looks perfect.

the flyout text looks really great, Graechan !

i had to use a bit of anisotropic smoothing, because the extrusion was loooking too jagged

and a variation

10 copies with Graechan's settings above

impressive outcome, K1te !

Don't know how I missed this thread but somehow I did.

Could somebody explain the maths behind the scaling factor please.

The "Final scale factor in X direction" represents the value by which the width of the original layer has to be multiplied so that obtaining what will be the width of the last duplicate.

For instance, supposing that the original layer features a width of 200 px, if we set the "Final scale factor in X direction" to 1.25, then the width of the last duplicate will be: 1.25 * 200 = 250 px.

As for the intermediate copies (if any), their widths will vary linearly between the width of the original layer and the one of the last duplicate.

In general, if n is the number of copies and a is the integer number representing the stage of duplication from which the scaling process must begin (as specified through the "Step to start transforming from" slider), we can express the width w(k) of the generic k-th duplicate by means of the following formula:

         /                 w(0)                                     ,    1 = k < a      
        /                                                                                
w(k) = <                                                                                 
        \                                                                                
         \  w(0) + [(k - (a - 1)) / (n - (a - 1))] * (w(n) - w(0))  ,    a ≤ k ≤ n - 1  

where w(0) and w(n) respectively symbolize the width of the original layer and the width of the last namely the n-th duplicate, while the latter value is obtained by multiplying the former by Sx , that is the final scale factor in X direction:

w(n) = sX * w(0)


For a = 1, we simply get:

w(k) = w(0) + (k / n) * (w(n) - w(0))  ,    1 ≤ k ≤ n - 1


With appropriate change of symbols, identical remarks apply to the "Final scale factor in Y direction".

Gino D - Thanks for the explanation, I think I've pretty much got the gist of it now.I have hacked the script to allow for 500 repeats to suit my requirements.

After mentioning in another thread about creating 3d perspective text going to a vanishing point thought I'd better take a look at the easiest way to do this.

I tried the method with three different vanishing points and three different methods of creating the lighting shadow on the text.

1. Standard bump map filter.
2. Esper and DD emboss filter tutorial
3. Using a white to black linear gradient.

The method is quite simple, decided where you want your vanishing point to be then create a square layer thats big enough to cover the object you wish to manipulate but making sure the centre of this layer is over the vanishing point.
Then merge the two layers together, its better to right click in the layers dialogue and use the merge visable layers option as this will not autocrop layers to image size.
Finally run the script, just make sure you uncheck "Autocrop Duplicates" and change Stack Duplicates to "below previous layer"

oh wow, the pink one is great

you should try posterize on the final picture, could give you an interesting vector-esque effect
