![]() ![]() normal : preserve the location and line breaks in each text block.exact : preserve the exact location of each individual character (a large and messy HTML).Y layout_mode Specifies how the page layout should be preserved. A Forces to perform layout analysis for all the text strings, This will reduce the memory consumption but also slows down the process. When this value is out of the range (e.g. 1.0 (only horizontal position matters) to 1.0 (only vertical position matters). F boxes_flow Specifies how much a horizontal and vertical position of a text matters The default valuesĪre M = 2.0, L = 0.5, and W = 0.1, respectively. The length to the size of each character in question. Represented as a space, but indicated by the positioning of each word.Įach value is specified not as an actual length, but as a proportion of ( W), as a blank between words might not be If the distance between two words is greater than the word_margin Also, two lines whose distance is closer thanĪs a text box, which is a rectangular area that contains a "cluster" of text portions.įurthermore, it may be required to insert blank characters (spaces) as necessary The char_margin (shown as M) is consideredĬontinuous and get grouped into one. In the figure below, two text chunks whose distance is closer than Therefore, text extraction needs to splice text chunks. In the middle of its running, depending on the authoring software. In an actual PDF file, text portions might be split into several chunks M char_margin -L line_margin -W word_margin These are the parameters used for layout analysis. I image_directory Specifies the output directory for image extraction.Ĭurrently only JPEG images are supported. Tags used here are defined in the PDF specification (See §10.7 " Tagged PDF"). pdf2txt tries to extract its content streams rather than inferring its text locations. A tagged PDF has its own contents annotated with Not recommended for extraction purposes because the markup is messy. The following formats are currently supported. p pageno Specifies the comma-separated list of the page numbers to be extracted.īy default, it extracts text from all the pages. Options -o filename Specifies the output file name.īy default, it prints the extracted contents to stdout in text format. (extract a text from an encrypted PDF file) $ pdf2txt.py -P mypassword -o output.txt secret.pdf (extract a Japanese HTML file in vertical writing, CMap is required) $ pdf2txt.py -V -c euc-jp -o output.html samples/jo.pdf (extract text as an HTML file whose filename is output.html) $ pdf2txt.py -o output.html samples/naacl06-shinyama.pdf Not all characters in a PDF can be safely converted to Unicode. You cannot extract any text from a PDF document which does not have extraction permission. ![]() ![]() You need to provide a password for protected PDF documents when its access is restricted. It also extracts the corresponding locations, font names, font sizes, writingĭirection (horizontal or vertical) for each text portion. It cannot recognize text drawn as images that would require optical character recognition. text represented as ASCII or Unicode strings. It extracts all the text that are to be rendered programmatically, Pdf2txt.py extracts text contents from a PDF file.
