Orion example is failing #28

Closed mrosseel closed 1 year ago

mrosseel commented 1 year ago

For the standard orion example:

from starplot import MapPlot, Projection, SkyObject
from starplot.styles import PlotStyle, extensions

style = PlotStyle().extend(
    extensions.BLUE_LIGHT,
    extensions.MAP,
    {
        "bayer_labels": {
            "font_name": "GFS Didot",  # use a better font for Greek letters
            "font_size": 7,
            "font_alpha": 0.9,
        },
    },
)
style.star.label.font_size = 11

p = MapPlot(
    projection=Projection.MERCATOR,
    ra_min=3.6,
    ra_max=7.8,
    dec_min=-16,
    dec_max=23.6,
    limiting_magnitude=7.2,
    style=style,
    resolution=3600,
)
p.plot_object(
    SkyObject(
        name="M42",
        ra=5.58333,
        dec=-4.61,
        style={
            "marker": {
                "size": 10,
                "symbol": "s",
                "fill": "full",
                "color": "#ff6868",
                "alpha": 1,
                "zorder": 4096,
            },
            "label": {
                "font_size": 10,
                "font_weight": "bold",
                "font_color": "darkred",
                "zorder": 4096,
            },
        },
    )
)
p.export("03_map_orion.png", padding=0.5)

this is the error i'm getting, might be some version mismatch:

were you able to compile shapely from source in this environment? I'm still trying to reproduce this, but I'm thinking it must be some kind of version mismatch, as you suggested.

@mrosseel just to follow up on this, I was able to reproduce this issue with Python 3.11 + Pydantic 2.4 and just pushed a fix to PyPi (v0.3.3) -- it also seems that you don't have to compile shapely from source with Python 3.11 😃

after doing a poetry update starplot upgrading from 0.3.1 to 0.3.3 the Orion example now indeed works! Only getting some font warnings: findfont: Font family 'GFS Didot' not found., which I could resolve by choosing another font from the mac 'font book' app (Hack Nerd Font). The image seems correctly generated.
