![]() ![]() When layout=False: Adds spaces where the difference between the x1 of one character and the x0 of the next is greater than x_tolerance. extract_text(x_tolerance=3, y_tolerance=3, layout=False, x_density=7.25, y_density=13, **kwargs)Ĭollates all of the page's character objects into a single string. (See Issue #71 to understand the motivation.) Returns a version of the page with duplicate chars - those sharing the same text, fontname, size, and positioning (within tolerance x/y) as other characters - removed. objects for which test_function(obj) returns True. 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. Sadly, the encryption can also be a hindrance to the viewing of an archived document if the person trying to open it doesn’t have the password or the encryption algorithms used.Īs the PDF standard evolves, there may be new additions to the capabilities and restrictions in PDF/A as well.The output will be a CSV containing info about every character, line, and rectangle in the PDF. Encryption is one way used by companies to prevent any restricted material from being viewed by anyone who doesn’t have permission to. Lastly, PDF/A files cannot be encrypted for the very same reasons stated above. If the external resource referenced is not found, it can cause the document to not appear appropriately. In general, PDF/A does not allow the file to reference to any external resource as there is no telling whether that resource would be there or not. This ensures that those resources are always available. Pictures are allowed in a PDF/A document given that they are embedded, along with the fonts to be used in rendering the documents. You cannot embed audio, video, and executable files in a PDF/A since the PDF viewer would not be able to open those on its own and there is no telling whether the appropriate software for them would still be available in the future. The first major difference between PDF and PDF/A is the latters’ restriction when it comes to certain types of content. In order to preserve the information in the file and to ensure that the contents will still appear as it should even after a very long time of storage, PDF/A sets stricter standard than those used by PDF. PDF/A is a subset of PDF that is meant for archiving information. There is also a different type of PDF known as PDF/A. One major use of PDF is in digital book publication where all readers support this format. Adobe’s Portable Document Format, more commonly known as PDF, has become the worlds’ most used format for ensuring that a document appears as it should regardless of what computer is used to create or view it. ![]()
