This is my code

from pygerber.examples import ExamplesEnum, get_example_path
from pygerber.gerberx3.api.v2 import ColorScheme, GerberFile, PixelFormatEnum

GerberFile.from_file(
    "GerberKicad/dse_vmj_ex_004_legend_top.gbr",
).parse().render_raster(
    "output.png",
    dpmm=100,
    color_scheme=ColorScheme.COPPER_ALPHA,
    pixel_format=PixelFormatEnum.RGBA,
)

It shows

I got same error message when I parse a GBS file.
here is my code:

from pygerber.gerberx3.api.v2 import FileTypeEnum, GerberFile
parsed_file = GerberFile.from_file(
    "./80600_50_6-ISS1/80600_50_6-ISS1_bott_resist.GBS",
    file_type=FileTypeEnum.INFER_FROM_ATTRIBUTES
).parse()
print(parsed_file.get_info())
print(parsed_file.get_file_type())

here I attach my gerber zip file:
80600_50_6-ISS1.zip

please advise how to solve it.
Thanks,
Lily

@Rajkisan the problem in with your file is cause by incorrect zero coding mode. D is not an accepted value accoring to Gerber standard. Do you know how this zero coding mode should be interpreted?

%FSDAX44Y44*%

[Rajkisan]

What Can I do now?

[Argmaster]

Change declared coordinate format. Try L or T instead of D in FS extended fommand and see if one of them yields reasonable results.

If you determine and share here how to interpret D coordinate coding I can add support for it in PyGerber to mitigate this issue in the future.
