Is there any way of safely resetting the canvas state?Ĭookie settings Strictly necessary cookies But I can’t even reach that point since it seems that the canvas_answer.json_data seems to be lagging by one step behind the most recent drawing resulting in a continuous ping pong between the two states. Where the st.session_state is set to True during the saving of the segmentation. St.session_state = canvas_answer.json_data If st.session_stateĮlse st.session_state, I am trying to use it as a form of segmentation tool but I can’t manage to reset the canvas even if I reset the initial_drawing as follows: canvas_answer = st_canvas(īackground_image=Image.open(tiled_buildings), How is it possible to reset the canvas while changing the image displayed as well? ![]() Objects = pd.json_normalize(canvas_result.json_data) # need to convert obj to str because PyArrowįor col in lect_dtypes(include=).columns: #if canvas_result.image_data is not None: # Do something interesting with the image data and paths Point_display_radius=point_display_radius if drawing_mode = 'point' else 0, Double click on label to delete.", False) else drawing_mode, Image_to_label = imported_imagesīackground_image=_image if imported_images else None,ĭrawing_mode="transform" if st.checkbox("Click for edition mode.

Accordingly, I like the canvas size match the shape of the corresponding current image. After I uploaded multiple images, I like to update the canvas with the next image from the list of uploaded files (st.file_uploader module). ![]()
