Parameters ---------- label : str A short label explaining to the user what this widget is used for. The label can optionally contain GitHub-flavored Markdown of the following types: Bold, Italics, Strikethroughs, Inline Code, Links, and Images. Images display like icons, with a max height equal to the font height. Unsupported Markdown elements are unwrapped so only their children (text contents) render. Display unsupported elements as literal characters by backslash-escaping them. E.g., ``"1\. Not an ordered list"``. See the ``body`` parameter of |st.markdown|_ for additional, supported Markdown directives. For accessibility reasons, you should never set an empty label, but you can hide it with ``label_visibility`` if needed. In the future, we may disallow empty labels by raising an exception. .. |st.markdown| replace:: ``st.markdown`` .. _st.markdown: https://docs.streamlit.io/develop/api-reference/text/st.markdown key : str or int An optional string or integer to use as the unique key for the widget. If this is omitted, a key will be generated for the widget based on its content. No two widgets may have the same key. help : str or None A tooltip that gets displayed next to the widget label. Streamlit only displays the tooltip when ``label_visibility="visible"``. If this is ``None`` (default), no tooltip is displayed. The tooltip can optionally contain GitHub-flavored Markdown, including the Markdown directives described in the ``body`` parameter of ``st.markdown``. on_change : callable An optional callback invoked when this camera_input's value changes. args : tuple An optional tuple of args to pass to the callback. kwargs : dict An optional dict of kwargs to pass to the callback. disabled : bool An optional boolean that disables the camera input if set to ``True``. Default is ``False``. label_visibility : "visible", "hidden", or "collapsed" The visibility of the label. The default is ``"visible"``. If this is ``"hidden"``, Streamlit displays an empty spacer instead of the label, which can help keep the widget alligned with other widgets. If this is ``"collapsed"``, Streamlit displays no label or spacer. Returns ------- None or UploadedFile The UploadedFile class is a subclass of BytesIO, and therefore is "file-like". This means you can pass an instance of it anywhere a file is expected. Examples -------- >>> import streamlit as st >>> >>> enable = st.checkbox("Enable camera") >>> picture = st.camera_input("Take a picture", disabled=not enable) >>> >>> if picture: ... st.image(picture) .. output:: https://doc-camera-input.streamlit.app/ height: 600px ) rDrErGrIrKrMrBrCctx)r _camera_input) r.rDrErGrIrKrMrBrCrQr1r1r2r@Ys_zCameraInputMixin.camera_input)rBrCrQrQScriptRunContext | Nonec Cst|}t|j||dddt||td|t|j||d} t} | | _|| _t|j| _ || _ t || j _ |dur@t|| _t} t| j|||| j| j| dd} |jd| t| j tradS| j S)NF) default_valuewrites_allowedr@)user_keyform_idrDrGfile_uploader_state_value)on_change_handlerrKrM deserializer serializerrQ value_type)rr dgr rr CameraInputProtoidrDrWrBrrCvaluerrGr!rr;r3_enqueuer%r)r.rDrErGrIrKrMrBrCrQ element_idcamera_input_protoserdecamera_input_stater1r1r2rRsR     zCameraInputMixin._camera_inputrcCs td|S)zGet our DeltaGenerator.r)r)r.r1r1r2r]s zCameraInputMixin.dg)NNNNN)rDr7rErFrGrHrIrJrKrLrMrNrBrOrCrr#rP)rDr7rErFrGrHrIrJrKrLrMrNrBrOrCrrQrSr#rP)r#r)r<r=r>rr@rRpropertyr]r1r1r1r2r?Xs. n ?r?)6 __future__r dataclassesrtextwraprtypingrrrtyping_extensionsr*streamlit.elements.lib.file_uploader_utilsr !streamlit.elements.lib.form_utilsr streamlit.elements.lib.policiesr r streamlit.elements.lib.utilsr rrrr(streamlit.elements.widgets.file_uploaderrstreamlit.proto.CameraInput_pb2rr^streamlit.proto.Common_pb2rr$rUploadedFileInfoProtostreamlit.runtime.metrics_utilrstreamlit.runtime.scriptrunnerrrstreamlit.runtime.staterrrr'streamlit.runtime.uploaded_file_managerrrstreamlit.delta_generatorrr __annotations__r!r?r1r1r1r2s.
