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 ) rCrDrFrHrJrLrArBctx)r _camera_input) r-rCrDrFrHrJrLrArBrPr0r0r1r?Vs_zCameraInputMixin.camera_input)rArBrPrPScriptRunContext | 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_idrCrFfile_uploader_state_value)on_change_handlerrJrL deserializer serializerrP value_type)rr dgr rr CameraInputProtoidrCrVrArrBvaluerrFr rr:r2_enqueuer$r)r-rCrDrFrHrJrLrArBrP element_idcamera_input_protoserdecamera_input_stater0r0r1rQsR     zCameraInputMixin._camera_inputrcCs td|S)zGet our DeltaGenerator.r)r)r-r0r0r1r\s zCameraInputMixin.dg)NNNNN)rCr6rDrErFrGrHrIrJrKrLrMrArNrBr r"rO)rCr6rDrErFrGrHrIrJrKrLrMrArNrBr rPrRr"rO)r"r)r;r<r=rr?rQpropertyr\r0r0r0r1r>Us. n ?r>)4 __future__r dataclassesrtextwraprtypingrrrtyping_extensionsr!streamlit.elements.lib.form_utilsr streamlit.elements.lib.policiesr r streamlit.elements.lib.utilsr r rrr(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>r0r0r0r1s,
