Note: kwargs annotated with ^ can only be used with flavor='stream' or flavor='network' and kwargs annotated with * can only be used with flavor='lattice'. The hybrid parser accepts kwargs with both annotations. Parameters ---------- filepath : str, Path, IO Filepath or URL of the PDF file. pages : str, optional (default: '1') Comma-separated page numbers. Example: '1,3,4' or '1,4-end' or 'all'. password : str, optional (default: None) Password for decryption. flavor : str (default: 'lattice') The parsing method to use ('lattice', 'stream', 'network' or 'hybrid'). Lattice is used by default. suppress_stdout : bool, optional (default: False) Print all logs and warnings. parallel : bool, optional (default: False) Process pages in parallel using all available cpu cores. layout_kwargs : dict, optional (default: {}) A dict of `pdfminer.layout.LAParams `_ kwargs. table_areas : list, optional (default: None) List of table area strings of the form x1,y1,x2,y2 where (x1, y1) -> left-top and (x2, y2) -> right-bottom in PDF coordinate space. columns^ : list, optional (default: None) List of column x-coordinates strings where the coordinates are comma-separated. split_text : bool, optional (default: False) Split text that spans across multiple cells. flag_size : bool, optional (default: False) Flag text based on font size. Useful to detect super/subscripts. Adds around flagged text. strip_text : str, optional (default: '') Characters that should be stripped from a string before assigning it to a cell. row_tol^ : int, optional (default: 2) Tolerance parameter used to combine text vertically, to generate rows. column_tol^ : int, optional (default: 0) Tolerance parameter used to combine text horizontally, to generate columns. process_background* : bool, optional (default: False) Process background lines. line_scale* : int, optional (default: 40) Line size scaling factor. The larger the value the smaller the detected lines. Making it very large will lead to text being detected as lines. copy_text* : list, optional (default: None) {'h', 'v'} Direction in which text in a spanning cell will be copied over. shift_text* : list, optional (default: ['l', 't']) {'l', 'r', 't', 'b'} Direction in which text in a spanning cell will flow. line_tol* : int, optional (default: 2) Tolerance parameter used to merge close vertical and horizontal lines. joint_tol* : int, optional (default: 2) Tolerance parameter used to decide whether the detected lines and points lie close to each other. threshold_blocksize* : int, optional (default: 15) Size of a pixel neighborhood that is used to calculate a threshold value for the pixel: 3, 5, 7, and so on. For more information, refer `OpenCV's adaptiveThreshold `_. threshold_constant* : int, optional (default: -2) Constant subtracted from the mean or weighted mean. Normally, it is positive but may be zero or negative as well. For more information, refer `OpenCV's adaptiveThreshold `_. iterations* : int, optional (default: 0) Number of times for erosion/dilation is applied. For more information, refer `OpenCV's dilate `_. backend* : str, optional by default "pdfium" The backend to use for converting the PDF to an image so it can be processed by OpenCV. use_fallback* : bool, optional Fallback to another backend if unavailable, by default True resolution* : int, optional (default: 300) Resolution used for PDF to PNG conversion.
