My plays with your last 3 images posted.

I am struggling to keep up!

Nice dress/skirt, teapot. lol

It is always so pleasant to see your results in the photos. I really like the focus that you give to the photos, each one of you.
Dinasset, David, teapot thank you.
David, how did you get the 5611-1 pencil effect?
teapot, your creation is spectacular and very funny, the result is very good.

@Issabella,

IMG_5611. I used Picture to Line Art. On the "visible" (Burn) layer moved the bottom point of Curves to the right until there was enough black.
New from Visible. Added a new layer and filled with yellow (ffff00). Changed this layer to LCh Colour mode.
Reduced the saturation of this layer or it's opacity to make the background a pale cream - either method produces the same result.

Thank you so much David. You know to get the best look for each photo. I'll try to do it..

@Issabella,

An improvement on what I suggested.
If you put the coloured layer in LCh Colour mode directly above the visible (Burn) layer - that is to say, no New from Visible layer, it allows adjustment of the previous layers to create other results.
This example was by increasing the contrast of the desaturated layer using curves.

I thank you for the explanation. I got the previous result as you told. I'll try this last steps, too. Thanks David.

@Issabella,

Perhaps you might like to try the latest variation. I have modified the Picture to Line Art plug-in to include the option to set a paper-colour.
(Apologies to Tim for mutilating his script yet again!!!)

Attached is the script. Comments, suggestions and criticisms are most welcome!



Edit: The file is now updated to the latest version.
The changes:
1. If there is a pre-existing selection it is saved to a channel for future use.
2. Added the option to select an "ink" colour in addition to the "paper" colour.
3. The layers have been renamed, hopefully to something more meaningful.

Altering the opacity of any of the layers (except the base layer) can create a wide range of effects.

Thank you so much David. My comment; It's easier and practical your plug-in. Nice results.
Of course, Thanks Tin. I love this effect so much.
Thanks to both of you.

Very nice river view lineart Issabella.

Lyle and Issabella, Thank you for your nice comments

David, I too like your line art made from image IMG_5611

Thank you for the picture_to_line_art plugin. I tried the version you uploaded to post #271 with IMG_5611 but it made the first copy layer all black.

After comparing with an older version of the plugin I think it's caused by this line:
pdb.gimp_drawable_curves_spline(layer_copy, HISTOGRAM_VALUE, 6, [0, 0, 157, 110, 255, 255])

which was this in the older version that worked for me:
pdb.gimp_curves_spline(layer_copy, HISTOGRAM_VALUE, 6, [0, 0, 157, 110, 255, 255])

I took a guess and tried the following which gave a result like the old version:
pdb.gimp_drawable_curves_spline(layer_copy, HISTOGRAM_VALUE, 6, [0.0, 0.0, 0.615, 0.431, 1.0, 1.0])

I don't know why that is in my case when it's working for you and Issabella.

Sorry. I must clarify that I did my test with David's plug-in having previously removed Tim's. The two plug-ins were not together in my folder when I did my test.
Teapot, try to remove Tim's plug-in and leave David's to do your test.

@teapot,

Thanks for your valuable feedback. The reason for the difference, I believe, is that your colour selector is set to specify colours as floating-point numbers, whereas mine uses the range 0-255.

I am working on a solution, but don't hold your breath!!!

I also discovered that I had forgotten in the script to convert greyscale images to RGB, which results in the paper-colour not appearing. This will be corrected in the next revision.

@teapot,

Despite spending most of the day on this problem, I have not yet been able to come up with a solution!

I have attached my latest version which, at least, now works for greyscale images.



Edit: See #271 (above) for the latest version.

Two more photos - these are ones that I found difficult to achieve the result I wished for.

You got it! David. The green plant took relevance with the background. The little bird is nicer.
I post these tw more photos.
One, it is part of the facade of the Cathedral of my city.
Other one it's from the garden of a friend of mine.
Last one it is a result with David's plug-in ( I love it)

My plays on your last two photos, Issa.
