gerbolyze's Issues

Hi there, thanks for the package. Is there any way we can integrate this into a python file?? any resources that we can refer? I want to convert svg file into gerber and show them in a website

SystemError: resvg executable not found

Based on the documentation it seems that one doesn't need to install 'resvg' unless one wants to speed up execution.

However, running 'gerbolyze template', I get the following error:

  File "/mydata/gerbolyze/venv/bin/gerbolyze", line 5, in <module>
    gerbolyze.cli()
  File "/mydata/gerbolyze/venv/lib/python3.10/site-packages/click/core.py", line 1130, in __call__

SystemError: resvg executable not found```

Note: I also don't have 'rust' or 'cargo' installed -- are they prerequisites?  I don't see them mentioned in the docs except in the seemingly optional section of speeding up with native binaries.

Problem with SVG image containing hollow cutouts

I am trying to use svg-flatten to convert SVG images to kicad footprints (silkscreen graphics).
My drawings contain multiple closed shapes with cutouts but these are rendered as plain filled areas, here are original image from inkscape and result in kicad:

Am I missing something or do I need specific preparation of the SVG file ?

The command line I use is:
svg-flatten --format kicad --sexp-layer F.SilkS --sexp-mod-name tentacles_02 tentacles2.svg ../pcb/drawings.pretty/tentacles_02.kicad_mod

Thank you very much 😀

Gerbolyze convert fails silently when an SVG contains a polygon with a large number of points.

Description

Gerbolyze fails to produce all layers contained in a template SVG generated by the empty-template sub-command when one of the layers contains a polygon with many points. The following can be used to generate a test SVG as well as demonstrate that the directory is lacking the expected set of files:

import numpy as np
import subprocess

from bs4 import BeautifulSoup
from pathlib import Path

def generate_polygon_and_append(soup, layer, radius, point_count=5e5, **kwargs):
    theta_array = np.linspace(0, 2*np.pi, num=int(point_count))
    # don't remember how numpy concat works rn so do it ugly
    point_array = np.array([radius * np.cos(theta_array), radius * np.sin(theta_array)]).transpose() + radius
    points = ' '.join([f'{x}, {y}' for (x, y) in point_array])
    layer.append(soup.new_tag('polygon', points=points, **kwargs))

def recursive_rmdir(directory):
    directory = Path(directory)
    for item in directory.iterdir():
        if item.is_dir():
            rmdir(item)
        else:
            item.unlink()
    directory.rmdir()

def main(output_dir='./gerbolyze_polygon_size_test', svg_template_name='gerbolyze_polygon_size_test.svg', point_count=512):
    output_dir_path = Path(output_dir).resolve()
    print(output_dir_path.as_posix())
    output_dir_path.mkdir(parents=True, exist_ok=True)
    svg_template_name_path = output_dir_path.joinpath(svg_template_name)
    if svg_template_name_path.exists():
        svg_template_name_path.unlink()

    maximum_radius = 50

    # Call Gerbolyze to generate an empty template SVG.
    command = ['gerbolyze', 'empty-template', f'--size {2*(maximum_radius)}x{2*(maximum_radius)}mm', svg_template_name_path.as_posix()]
    subprocess.run(' '.join(command), shell=True)

    # Open file we just generated.
    with svg_template_name_path.open() as svg_template:
        svg_template_soup = BeautifulSoup(svg_template, 'xml')

    # Construct SVG.
    for layer in svg_template_soup.find_all('g'):
        if layer['id'] == 'g-top-copper':
            generate_polygon_and_append(svg_template_soup, layer, maximum_radius)
        if layer['id'] == 'g-bottom-copper':
            generate_polygon_and_append(svg_template_soup, layer, maximum_radius)

    with svg_template_name_path.open('w') as svg_template:
        svg_template.write(svg_template_soup.prettify())

    # Call Gerbolyze program to convert SVG to Gerber.
    gerber_dir_path = output_dir_path.joinpath('gerber')
    if gerber_dir_path.exists():
        recursive_rmdir(gerber_dir_path)
    command = ['gerbolyze', 'convert', svg_template_name_path.as_posix(), gerber_dir_path.as_posix()]
    subprocess.run(' '.join(command), shell=True)

if __name__=='__main__':
    main()

This python script will create a directory called gerbolyze_polygon_size_test, populate it with a template SVG generated by Gerbolyze with two large polygons (with 5e5 points) added to the top and bottom copper layers, then call Gerbolyze to convert this SVG to Gerber files in a new subdirectory called gerber. The result of this on my machine appears as follows:

$ ls -hall ./gerbolyze_polygon_size_test/gerber_validation 
total 13M
drwxr-xr-x 2 luke users   6 Mar 19 21:52 .
drwxr-xr-x 4 luke users   5 Mar 19 21:52 ..
-rw-r--r-- 1 luke users 13M Mar 19 21:52 gerbolyze_polygon_size_test-F.Cu.gbr
-rw-r--r-- 1 luke users  86 Mar 19 21:52 gerbolyze_polygon_size_test-F.Mask.gbr
-rw-r--r-- 1 luke users  86 Mar 19 21:52 gerbolyze_polygon_size_test-F.Paste.gbr
-rw-r--r-- 1 luke users  86 Mar 19 21:52 gerbolyze_polygon_size_test-F.SilkS.gbr

Notably, this is missing the bottom copper layer, which we know in this case has elements in the SVG.

Expected Behavior

First, Gerbolyze should not fail silently in these cases - there should be some sort of warning or failure reported, which is not the case when I run this (from my shell, the python script is not hiding any stdout). Second, this probably shouldn't fail at all - the layers that are written appear to be correct when zipped and viewed with the Gerber viewer tool in KiCad. This level of resolution is useful for me, as I am using geometry from the boundary edges of a face of a high-resolution, manifold mesh to construct polygons in the template SVGs.

How do you increase resolution of included images

I used Inkscape to add a high resolution JPEG photo to the bottom silkscreen layer.
I tried both with the original 9MB color image and separately with a 17MB B&W dithered version of the same image.
The resulting SVG templates output by Inkscape ended up being 14MB and 23MB respectively -- so the resolution was captured by Inkscape.

In both cases, the resulting Gerber file showed only a very low resolution image (though still a little higher than the native image import tool in EasyEDA). Note that the Gerber zip file increased by only about 1.5MB.

(Interestingly, when I used Inkscape to crop the same image and then resized the smaller cropped image to the same size as the original, the resolution of the Gerber image was even worse with larger 'circles')

I am using the default settings (and thus presumably the default vectorizer) in 'gerbolyze paste'.

Is there any way to increase the resolution?
(e.g., setting the minimum size of the poisson discs/squares/hex etc)
It would seem that the silkscreen layer should handle finer resolutions -- after all it prints tiny letters and thin lines.

How to delete and how to update

Add to the description how to delete and how to update gerbolyze

Documentation mentions 'gerbolyze template' option called '--bbox' but doesn't seem to exist

Running
gerbolyze template --bbox x,y [--bottom|--top] etc.
gives error:

Try 'gerbolyze template --help' for help.

Error: No such option: --bbox```

Documentation for svg-flatten CLI incorrect

I've just installed the package through pip on OSX Ventura 13.4.1. I was struggling with using the svg-flatten module since the documentation says to call it with

svg-flatten [options]

This, however, results in an error that the module cannot be found.

Then I looked into the setup.py for the svg-flatten module and found that the script should be called using

wasi-svg-flatten [options]

Now it works with no problem.

Should either the documentation or the setup.py file be updated?

svg-flatten stuck on gerbolyze::dehole_polytree()

Hi,

When trying to generate gerbers from SVGs for internal PCB layers, I had a case of svg-flatten being stuck forever.
I edited the shape in Inkscape, and I trimmed in order to get the simplest shape that causes the issue.

Looking at the code, it seems gerbolyze::dehole_polytree() is stuck in an infinite loop.
I tried debugging further but I need to familiarize myself more with that code at the moment.

Minor issue: Git clone doesn't point to a branch

Running the suggested command:
git clone --recurse-submodules https://git.jaseg.de/gerbolyze.git
gives the following error:
warning: remote HEAD refers to nonexistent ref, unable to checkout.

Workaround is to run:
git branch -a
and then checkout one of the branches, e.g.,
git checkout main

Suggest either this is "fixed" or noted in the documentation.

very cool!

thanks! this is what i always want to do with svg2sz but have no time and clue, im looking a way to integrate to svg2sz...

USVG_OPTIONS='--keep-named-groups' required

I'm trying to use this tool, but I have to yet succeed once. So far I managed to find one problem: usvg seems to be removing all groups from the svg file, unless we tell it not to with the --keep-named-groups option. Simply adding USVG_OPTIONS='--keep-named-groups' before the gerbolyze command does that, and gets rid of the Corresponding overlay layer not found. Skipping. errors.

I'm still getting empty output, though, so there must be more bugs to find.

No Change using --scale or --usvg-dpi

Hi;
This is an incredible toolbox, well done on making it!

I've been experiencing an issue related to illustrator exporting SVG that are scaled wrong. This has to do with the viewbox field in the SVG. There are numerous issues in online forums about this within illustrator.

I thought I might be able to account for this (scaling by 0.66) in command line with Gerbolyze.
I've invoked svg-flatten --format svg --scale 0.66 /home/path/to/svg.svg /home/path/to/out.svg
I've also tried
svg-flatten --format kicad --sexp-mod-name TestModule --scale 0.66 /home/path/to/svg,svg /home/path/to/out.kicad_mod

I've also tried to address this with the --usvg-dpi flag, but also have seen no effect.
I've tried svg-flatten --format kicad --sexp-mod-name TestModule --usvg-dpi 72 home/path/to/svg.svg /home/path/to/out.kicad_mod

I get no acknowledgement of either of these switches being thrown, but I also get no errors. Am I missing something on when these can be toggled?

I've attached a troublesome SVG (hilarious that Github doesn't support SVG uploads) to this post if anyone wants to experiment. It should be 53.3 x 32.3 mm. It seems to always come into KiCad as 151 x 92 mm
2_nostroke_clipping_mask_noresp.zip

better instructions how to use this would be appreciated.

I have a really hard time to get this running, help is appreciated.
If I run "gerbolyze convert test.svg test.gbr" on my machine (WSL linux on Windows 11) I get the following error which I am not sure what the problem is. I assume that the test.svg in the repository good, but I am not even sure about that?

Using paste command / Problem with gerbv

Hi,

when I try to use gerbolyze paste I get an error. It seems like there is a problem with gerbv. But I'm not sure, if I did something wrong or if something else is broken.
I'm on macOs 11.3.1

subprocess.CalledProcessError: Command '['gerbv', '-x', 'svg', '--border=0', '--origin=4.972441x-5.032677', '--window_inch=3.103150x1.131890', '--foreground=#ffffff', '-o', '/var/folders/dd/fmghlwq1677bxlf1n9f_qjwm0000gn/T/tmpu2mco5z3/dilate-tmp.svg', 'oscger/OSC-F_Mask.gbr']' returned non-zero exit status 1.

When using Gerbolyze paste, the program throws an error after the Overlay Mechanical Outline layer.

In this instance, KicadGerberOUT is the original set of gerber files, input.svg is an inkspace SVG made with the template from gerbolyze template, and KicadGerberIN is an empty output directory.

gerbolyze convert generates... nothing, or a bunch of identical broken files?

I'm trying to get the protoboard generator working again, and I've mostly succeeded, but I'm running into something I haven't managed to chase down in the bowels of gerbolyze: the gerber files made seem to be broken or blank. I need help pinpointing the issue. For an example, I will use a file generated by generate_protoboards.py, called output_protoboards/svg/tht_normal_pitch100mil_large_holes/no_mounting_holes/tht_normal_pitch100mil_large_holes_30x40.svg (referred from now on as proto.svg)

When I run the command that export_protoboards.py would run, I get a pile of tiny, identical gerber files:

This looks incorrect. I'd at least expect some of the files to be different from each other...

Possible Windows (or alternately web) version?

Hi!

I've been following the project for a while now and I love the results you are getting. Dithering rocks.

I see that there is a macOS build via homebrew. Is there an easy way to run this in Windows without resorting to a docker container or something similar? A way to build this in windows would be great, or something akin to homebrew, or even just a little portable app. I know a webUI version is far more complicated as well but I've seen a lot of projects in this space also use those so that might be looking into.

Thank you so much for your work so far! The results are gorgeous.

Error trying to use svg-flatten

Hi,

I'm trying to test the svg-flatten code using the provided test images:

./svg-flatten --format gerber last_dash.svg dash.grb

but I get this error: Error: Cannot find usvg. Is it installed and in $PATH?

Can you please tell me what am I missing?

Thank you.

Best,
Radu

Examples

Can we get at least one step by step example how to use this tool?
There're some command lines in description but they show options that are not documented anywhere and in general I have no idea how to make my SVG files into gerbers. how to prepare them, etc.

Add smarter background handling

Currently, when converting an SVG file with black background and white foreground using --format gerber will produce clear gerber primitives on top of clear background in the output. We should figure out a way to handle this properly in all cases.

Simply pasting a rect of the same color as the background behind everything will not work properly since that may actually change the bounding box of the design. Possibly the best way to deal with this might be to add some logic to catch this case that will advertise the --flip-gerber-polarity flag.

See #13.

gerbolyze only fills coutouts

Hey, I ran into a problem. My board has a few cutouts and gerbolyze vectorize rendered my image only onto/into the cutouts, is there a quick fix for this problem?

Thank you in advance, gerbolyze is an amazing tool! :)

https://gerbolyze.jaseg.net/ only gives `Internal Server Error`

I tried using the website for this code, but it only gives me Internal Server Error when trying to open/download files. Is it possible to get it fixed? I didn't find any contact info on it so I assumed this would be the place to ask.

Cannot Download Target Preview Image on Site

Hi, I'm trying to download the top and bottom image but I'm getting an Internal Server Error.

How do you use this with EasyEDA Gerber files

So, after finally getting gerbalyze template & paste to install and run in an Ubuntu Docker python3.10-pip environment (both using a full 'git' install and separately just using 'pip install'), I loaded the output files in several different Gerber viewers but the image I added in Inkscape didn't show up in the newly created Gerber file.

My steps were as follows:

Export Gerber file from EasyEDA
Run gerbalyze template --bottom easyeda.zip output.svg - No errors though a couple of warnings (see below)
Open 'output.svg' in Inkskape and add/resize/move my image (a dithered high res B&W photo) to the bottom silkscreen level (called 'bottom-silk'). Save the image to output-image.svg
Run gerbalyze paste easyeda.zip output-image.svg easyeda-image.zip - No errors though a couple of warnings (see below)
Load 'easyeda-image.zip' into a Gerber viewer

The resulting top and bottom board views looked the same as the original -- i.e., no image added.
When I looked inside and compared the new and original zip files, I found that

Some layers in the original Gerber file were deleted (e.g., Gerber_TopAssemblyLayer.GTA, Gerber_DocumentLayer.GDL, Gerber_DrillDrawingLayer.GDD, How-to-order-PCB.txt -- presumably at least the last one is not really relevant)
The individual file sizes were all slightly smaller -- hopefully, no essential data was lost
No evidence of an image being added (as all files were smaller than their original counterparts)

Specifically, the files before looked like:

And after looked like:
```Archive:  Gerber_PCB4_2023-04-18-new.zip

---------                     -------
   635163                     10 files```

So in summary:
- Has anything been lost by deleting the listed files and by (slightly) shortening the existing remaining files
- Why wasn't the image added?
- Could the problem be that EasyEDA uses a different Gerber file format and/or layer naming/id than KiKaid?
- What do I need to do to make this work for EasyEDA Gerber files in general and my case in specific?


Note the warnings I got were as follows:

Bezier flattener flattens beziers too much

I'm trying to get some icons onto my silkscreen, but no matter what I try it comes out super "low resolution", for lack of a better term. Specifically circles seem to become rotated squares.

For example, I tried various music note icons from various websites:

https://www.svgrepo.com/vectors/music/monocolor/
https://feathericons.com/?query=note
https://remixicon.com/

(any of those should do)

I put them on the silk layer in inkscape. I've tried embedding png images but that didn't get included in the silk layer at all. Had to draw some primitives onto the silk layer to make sure the process is working end to end. All I've gotten to show up on the gerber is if I drag in a svg file and choose to include it (first radio button. ie. not as an image tag).

This is just a test to get some screenshots. When I make the icons smaller (which would be my intention for how I'd want to use it in this case) the effect is even more pronounced.

Is there something obvious I'm missing? A setting I have to change perhaps? Would be nice if the round parts looked a bit rounder.

MacOS support?

Howdy, thank you for all of the work you've put into this! I would love to be able to use this on MacOS.

Since this could significantly make my life easier I'm happy to pay to see this feature - either via github sponsorship, ko-fi, paypal, or a donation to a non-profit of your choice.

Thanks again for this! 💜

Possible output resolution error with render command

Hey first of all thanks for making this amazing tool!
I am running into a possible issue with how the render command is outputting an image. I have a pcb project with dimensions of 91x37mm(3.57x1.46 inches). However when I run the gerbolyze render command on the gerber files (gerbolyze render top gerber_files output.png), I get a png file with a resolution of 96 pixels(W) by 235 pixels(H).
However according to the default resolution setting (10px/6mils) I would be expecting a width of 2427 pixels (1456 mils / 6 mils * 10 pixels). I was able to get around this by setting the fab resolution to .238 which left me with a width of 2421 which was closer to what I was expecting. I'll be using the new output with custom fab resolution but I just wanted to let you know and was wondering if I am just doing something completely wrong. I'll include the gerber folder and 2 outputs in-case you wanna look into it.

Conversion results have no data except LPD/LPC by svg-flatten command with --flatten option

I use the svg-flatten command with the options of --force-svg --flatten -o gerber example.svg example.gtl to convert svg to gerber file. The files are paste below.
The Gerber content is weird as below. If I remove the option of --flatten, the output gerber is OK. If I want to flatten the svg, it will fail. Is there something I am missing?

Can't build on Ubuntu

I hate to be that guy who is clueless about what exactly is going wrong, but I really want to try out this software and can't get this to build in a fresh Ubuntu virtual machine.

Before I bother you too much with what's going wrong, can you tell me the exact version of python that I should be using to install, as it is ambiguous and depending on which version I try to use, I get different errors.

There's also some errors due to upgrading pip3 to a point where even running pip3 with no args will fail with syntax errors, I think because it's using a python older than 3.x

Just want a known good starting point to try first and then I can show you error logs while trying to get it installed.
