#### Options

- **--warnings** [default|ignore|once] - Enable or disable file format warnings during parsing (default: on).
- **-m, --input-map** `<json_file>` - Extend or override layer name mapping with name map from JSON file. The JSON file must contain a single JSON dict with an arbitrary number of string: string entries. The keys are interpreted as regexes applied to the filenames via re.fullmatch, and each value must either be the string `ignore` to remove this layer from previous automatic guesses, or a Gerbonara layer name such as `top copper`, `inner_2 copper` or `bottom silk`.
- **--use-builtin-name-rules / --no-builtin-name-rules** - Disable built-in layer name rules and use only rules given by `--input-map`.
- **--force-zip** - Force treating input path as a zip file (default: guess file type from extension and contents).

- **--command-line-units** `<metric|us-customary>` - Units for values given in other options. Default: millimeter.
- **--margin** `<float>` - Add space around the board inside the viewport.
- **--force-bounds** `<min_x,min_y,max_x,max_y>` - Force SVG bounding box to the given value.

- **--colorscheme** `<json_file>` - Load colorscheme from given JSON file. The JSON file must contain a single dict with keys `copper`, `silk`, `mask`, `paste`, `drill` and `outline`. Each key must map to a string containing either a normal 6-digit hex color with leading hash sign, or an 8-digit hex color with leading hash sign, where the last two digits set the layer's alpha value (opacity), with `ff` being completely opaque, and `00` being invisibly transparent.
```

--------------------------------

### Gerbonara Rewrite Command

Source: https://gerbolyze.gitlab.io/gerbonara/_sources/cli.rst.txt

Parses a single Gerber file, applies transformations, and re-serializes it into a new Gerber file. This command can be used to convert files to different settings or normalize them.

```APIDOC
## gerbonara rewrite

### Description

Parse a single gerber file, apply transformations, and re-serialize it into a new gerber file. Without transformations, this command can be used to convert a gerber file to use different settings (e.g. units, precision), but can also be used to "normalize" gerber files in a weird format into a more standards-compatible one as Gerbonara's gerber parser is significantly more robust for weird inputs than others.

### Method

`gerbonara rewrite`

### Endpoint

`gerbonara rewrite [OPTIONS] INFILE OUTFILE`

### Parameters

#### Options

- **--warnings** <default|ignore|once> - Enable or disable file format warnings during parsing (default: on).
- **-t, --transform** `<code>` - Apply a transformation to the Gerber file.

### Modify Solder Mask with Gerbonara

Source: https://gerbolyze.gitlab.io/gerbonara/_sources/examples.rst.txt

This script modifies solder mask layers in a KiCad-exported board file. It removes solder mask everywhere except for a thin ring around pads. The script assumes the solder mask layer is 'negative' and works with regions and arcs, converting them to shapely objects for offsetting.

```python
from gerbonara import *
from shapely import *

stack = layers.LayerStack.open('gerber')
# Let's work in mm here. Gerbonara will take care to convert units when the file is in US customary units.
(x1, y1), (x2, y2) = stack.bounding_box(unit=utils.MM)

for l in [stack['bottom mask'], stack['top mask']]:

    # The solder mask gerber layer by convention is "negative". That is, a "dark" polarity (drawn) Gerber primitive
    # will result in an opening in the solder mask. Conversely, an empty gerber file would lead to the entire board
    # being covered in solder mask.
    #
    # Here, we add a rectangle covering the entire board so the entire board is *free* of solder mask.

    new = [graphic_objects.Region(
        [(x1, y1), (x1, y2), (x2, y2), (x2, y1), (x1, y1)],
        unit=utils.MM,
        polarity_dark=True)]

    # Iterate through all objects on the solder mask layer. In later KiCad versions, everything on the solder mask
    # layer is exported as a Gerber region, which is a really bad idea, but makes things easy for us here.
    for obj in l.objects:
        if isinstance(obj, gerbonara.graphic_objects.Region):
            regions = []
        else:
            regions = [gerbonara.graphic_objects.Region.from_arc_poly(prim.to_arc_poly()) 
                for prim in obj.to_primitives(unit=gerbonara.utils.MM)]

        for obj in regions:
            # Convert the region to a shapely line string
            ls = LineString(obj.outline).normalize()

            # Ask shapely to offset the line string by 1 mm
            out = ls.offset_curve(obj.unit(1, 'mm'))

            # For negative offsets, this operation can result in an object being split up into multiple parts, so we
            # might get back a MultiLineString instead of a LineString.
            for ls in (out.geoms if hasattr(out, 'geoms') else [out]):

                # Convert the resulting shapely object back to a Gerber region.
                new.append(graphic_objects.Region(
                    unit=obj.unit,
                    polarity_dark=not obj.polarity_dark,
                    outline=list(ls.coords)))

    # Append the new objects to the original layer data
    l.objects = new + l.objects
# Write the modified layer stack to a new Gerber directory
stack.save_to_directory('output-gerbers')
```

- `--offset <COORDINATE>`: Offset for the n’th file as a `x,y` string in unit given by `--command-line-units`. Can be given multiple times, and the first option affects the first input, the second option affects the second input, and so on.
- `--rotation <ROTATION>`: Rotation for the n’th file in degrees clockwise, optionally followed by comma-separated rotation center X and Y coordinates. Can be given multiple times, and the first option affects the first input, the second option affects the second input, and so on.

This option can be given multiple times, in which case the n’th option affects only the n’th input. The JSON file must contain a single JSON dict with an arbitrary number of string: string entries. The keys are interpreted as regexes applied to the filenames via re.fullmatch, and each value must either be the string “ignore” to remove this layer from previous automatic guesses, or a gerbonara layer name such as `top copper`, `inner_2 copper` or `bottom silk`.
- `--default-settings, --reuse-input-settings`: Use sensible defaults for the output file format settings (default) or use the same export settings as the input file instead of sensible defaults.
- `--output-naming-scheme <altium|kicad>`: Name output files according to the selected naming scheme instead of keeping the old file names of the first input.
- `--output-board-name <TEXT>`: Override board name used with `--output-naming-scheme`.
