Regarding the halftone repeater types

thanks, will keep an eye on that

...The image nodes in Nodebox are also fascinating...
yes, and to be able to create your own Node add yet another Level to thisJohn from NB Forum, create the most of the user defined Nodes
he made also a whole little Library ( free to use ) which can be found here
http://support.nodebox.net/discussions/show-your-work/698-cartan-node-library-33the library comes with a PDF Doc

Voronoi Halftone is fascinating. I know a few free online generators for it, but most only support output as bitmaps. Let me recommend one that I particularly like, which supports PNG input and SVG output, but it has a seeds limit of 800.

Yes, this is really nice. But for now this will not be possible. Maybe in later versions.

Because of the Voronoi pattern, I thought of the Java programming language
“Processing”. which was developed specifically for graphical applications.There are some examples on “Openprocessing” of Voronoi patterns.
But there is much more possible with Processing you can program all kinds
of patterns. Which can then be output as a vector graphic.

@VectorStyler
The application of shape effects has been fixed, and the efficiency is incredibly high. Thank you!Halftone can now perform Area Halftone and Blend Halftone as well, with a speed that is a hundred times faster than the previously used VBA macro. I am grateful beyond words.
The Offset Halftone is almost there, but the scaling effect of an individual shape at different grayscale positions is not yet achieved, similar to the effect of width lines.

An example file for this might help.

@Li-Xiao Is there a vstyler file for this? or was this done in an other app?

It was done by another app. I have tried it with VS, but even version 1.2.019 cannot do it. -
Can be done, requires a few steps: 0_1712857903612_repeaterfile4.vstyler
- define a number variable "offset" of type "Number Slider", set the min/max to -0.6/0.6 and its value to 0.
- add the Offset Path effect to the "VS" text (offset should be small).
- set the offset distance to the "offset" variable (control+click on the distance number field and select "offset").
- create the repeater (offset is constant now).
- in the repeater panel menu, select "Adjust Number Values".
- select "offset" in Number and check the "Adjusted Number"
- set the Adjustment to "Object Content" and min/max to -0.5/0.5 (can use other values to different effect), confirm this.
- now what happens is that the "offset" number variable will vary using the background intensities between -0.5 and 0.5
But the good news is: this can be done with number variables and number fields with any effect, property etc in repeaters.

Using number variables in combination is a good approach, but mapping a single element to a grayscale value alone is not sufficient. Please take a look at the example.
-
@Li-Xiao yes, this is not yet possible. The offset must be the same in an object.
-
@VectorStyler
Yes, that's correct. Currently, the offset feature does not support mapping to grayscale values.I tried using the contour tool and manually expanded it by dozens before using the Repeater, but after several hours of attempts, I didn't achieve any results. I forgot to try using offset with variables.

Block-like Halftone

Unable to generate within Repeater.

Found a little Program made with Processing
which offers Circle Packing and a few other Styles
Results can be saved as SVG

@Subpath
Thank you! I used to use StippleGen (https://wiki.evilmadscientist.com/StippleGen) and HalftonePal before, but I haven't used them since I purchased DrawingBot. DrawingBot includes all the features of both of them. Kumiko (https://kumiko-generator.netlify.app/) is also interesting, DrawingBot is unable to replicate its effects. -
thank you too, for the links
and also for all of your interesting Ideas

Btw. I was following an Idea in Nodebox and it seems i came to a Solution
where you can replace a Shape in an .SVG File with any Shape you like.
Even with Text.
I used the Circle Packing .SVG from my post above and replaced the circle
with the text “Flower”.Import in VectorStyler works via exporting as .PDF from Nodebox
and then import the .PDF in VectorStyler
(.SVG does not work)Here a Example

Here the Nodebox Tree:

.
A short explanation of the Nodes
"Slice" will pick the Shape
"Centroid" calculate the Center of the Shape (Result is the Position)
"fit_to" fits the size of the Shape (Text) into the Size of the Circle
"rotate" allows to rotate the Text -
@Subpath Thank you, I will try Nodebox when I have time to see if it can create more unique designs.
The 1.2.019 update now allows me to create several other halftone styles that I wanted to submit.
Repeater is indeed powerful.
However, there is still room for improvement in terms of space filling and sorting.
