Diego, one question. I´m trying to make it work with bimp, but when i try to enter the information regarding palette name and others it just let me choose a number. Do you know what are the correct numbers on those dropdowns to make it work for patterns?
thanks a lot

The script is running light and as expected, with a little note for the Gradient option of BG/FG Colors.

When selecting FG/BG colors for Gradient, there is repeatability in the output produced, the random feature does not seem to be taken into account in this case, and only two areas were continuously painted (at least in the image I used as an experiment). Always giving the same shade of red (orange) and yellow.

Dinasset, the way the selected gradient is producing its result is very satisfactory (except when selected FG/BG rgb), but it would be possible to have a second option, where the painted result would be shown in gradient rather than in solid colors of the selected gradient?

If only one of the two options is possible, I would prefer the way the script is now. As in the sample - Gradient- Golden from the image below.

Thanks for extending the life of this script and for the 7-animals patterns available.

@regido
I'm not an expert of Bimp, but I presume the numbers it wants differ in each installation (i.e. depending on which palettes, gradients, patterns are installed in the specific user Gimp)
@Krikor
filling each area with a gradient could be an additional option, similar to the pattern option, i.e. using a different gradient in each area, but as a difference from the patterns a gradient requires additional parameters (how to "draw" the gradient, mode, starting point, ending point) and this will "complicate" this simple "divertissement".

@Krikor
using FGtoBG(RGB) I get different outcomes, not always the same.

Dinasset literally yes, different results, but visually very similar.
The images below are all different, generated from the same black and white original.
FG = ff0000 ; BG = ffee00



Ok, I like the result that the selected gradient produces. Thx

I can only guess that the Gimp function "gimp_gradient_get_uniform_samples" does not work as we could expect when the gradient has in fact only two start/end colours.
Just a guess.

edit:(or: let me better check...)

Sorry...
Found errors in my script; could you try now?
This is the amended version:

FG=FFFF00, BG=0000FF

What was good now is even better!
Dinasset, thanks for your efforts to improve this script and meet Gimpmaniac's wishes.

Krikor,
many thanks for your kind words and especially for your continuous testing, which let me remove some problematic errors.

Dinasset could you please take a look at that bimp thing i mentioned?
When i try to use it in the dropdown i can only put numbers, not text. I just want to fill everything with patterns, the patterns are called meme (meme1,meme2 etc)
This will be a lifesaver for me.
Thanks a lot for your great work

As I told you, I do not know BIMP, but -if for pattern it requires a number- this means clearly that it accepts just ONE SINGLE SPECIFIC pattern for parameter (for instance: the ninth in the list), therefore it is not possible to specify a string (like "meme") to select randomly among all the patterns having that specific string.
Sorry.

Let me think about a specific solution without the use of Bimp.
If I succeed, I will post it here.

@regido

I prepared a filter will calls the filter "filling" for any .png or .jpg file inside a selected input folder and places the outcome in a selected output folder.
To test it:
1.create (maybe on desktop, I did so for my tests) a folder containing some (not too many for the initial tests) B&W drawings which you will like to have filled on each area for instance by random patterns (I know you are more interested on fill-with-patterns, aren't you?)
2.prepare an empty folder for the outcomes that will be produced (must exist, before launching the filter!)
3.launch the "batch_filling" filter
4.choose your defined input folder
5.choose your defined output folder
6.run and wait the completion (you get a final message saying "processed n files")
Good luck and let me know.


(note: modified the "filling" by removing the info messages, to avoid annoying the user)

Diego this is great. Thanks a lot for your work it works perfectly.
Thanks a lot again, you´re a genius

Glad it works and can help you in your activity.

Quick question diego, do you have any idea on why this is happening? check the following photo

As you can see there´s a white border around the shape form.
Another question. If i use white and black and define white as the color to be replaced there´s a strange error where the pattern whites are also deleted. If i use green that doesn´t happen.
One suggestion. I think it would be great to give the possibility to remove the black lines right after the filling proccess is finished, it would be very helpful.

Thanks a lot in advance, you are very kind
Have a nice day

Problem 1:
It happens often, because the source is not "really" black and white.
Ensure the source is really black and white by running "threshold" first.
This is my outcome using Nidhogg's image after having applied threshold before running filling.

As you see, there are no white margins.

Problem 2:
I don't know, post your sources (both the black and white and the black and green)

Problem 3:
Replacing black with what?

PostScriptum:
concerning problem 3:
if the black lines are all of the same dimension, it can be used the "dilate" function of Gimp, try yourself and tell me if this if what you would see.

Because we live in different time zones, I took my decision without waiting for your reply.
This version removes the drawing lines (even if of different sizes).
Check and let me know.
