plotterfun's Issues

Add a licence

This is a really cool project and since it's JS based I could see myself using one of the algorithms on a client website, a simple MIT licence should suffice.

More than 500 divisions in halftone mode

Hello. I tried more than that on 4000*2000 image and this didn't work for some reason.

[Feature request] Connect squiggle ends

It's great to have these tools as a single useful web app. For squiggle plots, one useful feature that's missing is to 'connect ends' of each line, so the plotter has a continuous squiggle line that alternates between each endpoint, e.g.

The result is fewer pen lifts for each plot.

Here is the full svg that shows it, to open it, rename the file extension from 'zip' to 'svg'
mao_2121128.zip

You can find the connect ends switch implemented in the original Squiggledraw source.

The function is named 'connectEnds'

What are the odds of getting it implemented into plotterfun?
Maybe I could try and make a pull request for this but my java is rusty.

return pixData.data[i]*0.299 + pixData.data[i+1]*0.587 + pixData.data[i]*0.114 // ITU-R 601-2

Reading through this code to be able to implement a new algorithm. I noticed the third element in the addition doesn't add 2 to the index.

Add button 'Copy SVG to clipboard'

It would be useful to copy the generated SVG to the clipboard instead of saving it, because pasting the SVG into the target program is much quicker...

This could be useful: https://stackoverflow.com/questions/400212/how-do-i-copy-to-the-clipboard-in-javascript

Linedraw algorithm can't get the result

Hi, this is a great work that I like so much! Thanks for your work.

The problem is I have a bright image(a photo captured by camera and I adjust it to a very bright version, see attachment) input into the Lindraw algorithm, but get blank result.

I have tried original linedraw.py, it works fine. I attach the image file and the output of linedraw.py, please take a look.

Tuning the parameters makes no help.

Original image:

linedraw.py output:

Halftone creates nonsense vectors

Certain settings in the halftone tool create arcs of zero radius, leading to parsing errors in other svg tools.

ex. a 0.000 0.000 0 1 0 0.001 0Z

Example generated svg.

How to get controls to work?

I've been tinkering with a new algorithm. I don't code much any more, so it's taken longer than it should have! It's still a bit of a work in progress.

Thing is, I can't get the controls to have an initial value. It seems to be the value property but mine always have a value of 1. Any ideas?

postMessage(['sliders', defaultControls.concat([
  {label: 'Tile size', value: 60, min: 6, max: 100},
  {label: 'Lines', value: 6, min: 2, max: 50, step: 2},
  {label: 'Sublines', value: 3, min: 1, max: 10}
  ,{label: 'Amplitude', value: 0.1, min: 0.1, max: 5, step: 0.1}
  ,{label: 'Sampling', value: 5, min: 2, max: 10, step: 0.1}
])]);

Color mode

Your tool is so cool!!!
I made a color version but didn't test the result with my plotter up to now - https://grbl-plotter.de/plotterfun-color
Also drag & drop of an images on to the canvas is possible
To do: I can't change the order of the colors (the lightest color first would be nice), output scaled to given mm (somehow a factor of 3.78 is applied...)

[Feature Request] Open web image and non-popup progress indicator

I would wish that I could directly open images from a URL, and that, if plotterfun is recalculating, the popup wouldn't shift the whole layout when recalculating.

I am using Firefox 85.0.1 64-bit on Ubuntu 20.04.1 LTS.

Allow up/down arrows for input incrementation

I don't really get why they're text inputs and not number inputs

Paths in exported svg stretch outside the canvas, causing problems in other programs

Cricut Design Space refuses to import SVG-s if the image is bigger than the canvas. It's not a big deal to scale it down in Inkscape, but it's still an extra step.

Add new algorythm https://github.com/LingDong-/linedraw

Very nice collection!
Perhaps you could add this algorithm: https://github.com/LingDong-/linedraw
