The parameters horizontal_ltr and vertical_ttb indicate whether the words should be read from left-to-right (for horizontal words) / top-to-bottom (for vertical words). A similar approach is taken for non-upright characters, but instead measuring the vertical, rather than horizontal, distances between them. Words are considered to be sequences of characters where (for "upright" characters) the difference between the x1 of one character and the x0 of the next is less than or equal to x_tolerance and where the doctop of one character and the doctop of the next is less than or equal to y_tolerance. Returns a list of all word-looking things and their bounding boxes. extract_words(x_tolerance=3, y_tolerance=3, keep_blank_chars=False, use_text_flow=False, horizontal_ltr=True, vertical_ttb=True, extra_attrs=, split_at_punctuation=False) Page objects can call the following text-extraction methods: Method It can also attempt to preserve the layout of that text, as well as to identify the coordinates of words and search queries. Pdfplumber can extract text from any given page (including cropped and derived pages). (More details about policy.xml available here.) Extracting text You can use this method to flush the cache and release the memory. When parsing large PDFs, however, these cached properties can require a lot of memory. objects for which test_function(obj) returns True.īy default, Page objects cache their layout and object information to avoid having to reprocess it. Returns a version of the page with only the. within_bbox, but only retains objects that fall entirely outside the bounding box. outside_bbox(bounding_box, relative=False, strict=True) crop, but only retains objects that fall entirely within the bounding box. within_bbox(bounding_box, relative=False, strict=True) (See Issue #245 for a visual example and explanation.) When strict=True (the default), the crop's bounding box must fall entirely within the page's bounding box. If relative=True, the bounding box is calculated as an offset from the top-left of the page's bounding box, rather than an absolute positioning. If an object falls only partly within the box, its dimensions are sliced to fit the bounding box. ![]() Cropped pages retain objects that fall at least partly within the bounding box. Returns a version of the page cropped to the bounding box, which should be expressed as 4-tuple with the values (x0, top, x1, bottom). crop(bounding_box, relative=False, strict=True) imagesĮach of these properties is a list, and each list contains one dictionary for each such object embedded on the page. The sequential page number, starting with 1 for the first page, 2 for the second, and so on. Most things you'll do with pdfplumber will revolve around this class. The pdfplumber.Page class is at the core of pdfplumber. ![]() Typically includes "CreationDate," "ModDate," "Producer," et cetera.Ī list containing one pdfplumber.Page instance per page loaded. The top-level pdfplumber.PDF class represents a single PDF and has two main properties: PropertyĪ dictionary of metadata key/value pairs, drawn from the PDF's Info trailers. If that is not intended, pass strict_metadata=True to the open method and pdfplumber.open will raise an exception if it is unable to parse the metadata. Invalid metadata values are treated as a warning by default. Defaults to all available.Ī JSON-formatted string (e.g., '). types Ĭhoices are char, rect, line, curve, image, annot, et cetera. The json format returns more information it includes PDF-level and page-level metadata, plus dictionary-nested attributes.Ī space-delimited, 1-indexed list of pages or hyphenated page ranges. The output will be a CSV containing info about every character, line, and rectangle in the PDF.
