wolfhece.PyPictures.find_gps_in_file(picture: str | pathlib.Path) → tuple[float, float, float]

Find GPS coordinates in the picture file. Returns a tuple (latitude, longitude, altitude). If not found, returns (None, None, None).

wolfhece.PyPictures.find_exif_in_file(picture: str | pathlib.Path) → dict

Find EXIF data in the picture file. Returns a dictionary of EXIF data. If not found, returns an empty dictionary.

wolfhece.PyPictures.find_Lambert72_in_file(picture: str | pathlib.Path) → tuple[float, float]

Find Lambert72 coordinates in the picture file. Returns a tuple (Lambert72X, Lambert72Y). If not found, returns (None, None).

class wolfhece.PyPictures.PictureCollection(filename: str | pathlib.Path = '', ox: float = 0.0, oy: float = 0.0, tx: float = 0.0, ty: float = 0.0, parent=None, is2D=True, idx: str = '', plotted: bool = True, mapviewer=None, need_for_wx: bool = False, bbox: shapely.geometry.Polygon = None, find_minmax: bool = True, shared: bool = False, colors: dict = None)

Bases: wolfhece.PyVertexvectors.Zones

PictureCollection is a collection of pictures, inheriting from Zones.

_default_size = 200

hide_all_pictures()

Hide all pictures in the collection.

show_all_pictures()

Show all pictures in the collection.

extract_pictures(directory: str | pathlib.Path)

Extract all visible pictures from the collection to a directory.

add_picture(picture: str | pathlib.Path, x: float = None, y: float = None, name: str = '', keyzone: str = None)

Add a picture to the collection at coordinates (x, y).

_find_coordinates_in_file(picture: str | pathlib.Path) → tuple[float, float]

Find coordinates in the picture file. Returns a tuple (x, y). If not found, returns (None, None).

load_from_url_zipfile(url: str)

Load pictures from a zip file at a given URL. The zip file should contain images with names that can be used as picture names.

load_from_directory_with_excel(excel_file: str | pathlib.Path, sheet_name: str = 'Pictures')
