How paragraph extracted from Pdf using Adobe Pdf Library in c# or Java

Using this library I extracted the contents of the Pdf file.

I content line by line (using the last wordOnline)

Contents of < row > < / Line >

But I want to extract content paragraph by paragraph as

< Paragrph > content < / paragraph >

In this case, the notion of paragraph has no special meaning. It's an interpretation put on a layout by the human brain, which uses clues like the indentation and spacing between the lines to decide how to structure the text.

There is in fact no notion of setting or line spacing back in a PDF document either. There is only text, with positions. Increased line spacing could be inferred from a greater difference in the coordinate Y (but it could also be the largest type, or a space for an image). Indentation could be deduced from a largest abscissa of the first item in line (but this may be too complicated if the base line is changed, with respect to the indices and exponents).

Your program can make any decision he likes based on the text and its position, including guess what is a paragraph (or a margin or a column, or a reference, or header or footer...)  If your entry is compatible, you can have good success in these assumptions.

  • Commenting on PDFs with text from websites using Adobe

    Hi all

    I work in a team and we want to download articles, documents and Web sites deposits, convert them to PDF format, highlight and comment on the text.  Currently, we use Adobe Acrobat XI Standard to convert the Web site text in PDFs using OCR to recognize the text and then highlighting the text that recognizes the OCR.  Our team share the documents commented on an internal cloud.

    There are two problems with our process.  First of all, once the OCR recognizes text, it replaces the old text with new text which is a bit blurry, making it hard to read.  Second, the OCR takes a long time to run on long documents.

    Does anyone have any suggestions?  Is Adobe program more effective to use?

    Thanks for your help!

    Hi AdobeNewUser1,

    You can use the function 'Find and correct OCR Suspect' to fix the blurry replaced the OCR text.

    If the document is long so it is normal that the OCR engine to take the time to read the entire document.

  • How to disconnect from creative cloud Adobe on a pc so that I can re - install programs on another? (I already use one login at work)

    Hello

    Can someone tell me how I can re - install the Adobe programs on my new laptop at home? I know that we're allowed 2 installs, so I use one at work and one at home. Thank you!

    You can connect to https://creative.adobe.com/products and download the app CC, while it contains access to install it your authorized to.

    If you mean you want to install on another computer at home, which would be a third install, the second on a computer at home and one at work, simply login to Office CC of the older the home computer, and when you connect to CC Desktop on the third computer it will ask you to turn it off on the other two.  To do this, then do not connect to CC Desktop on another computer that you intend to use CC on, that would work.

  • GH4 - 4 k 4:2:0 to 1080 p 4:4:4 using Adobe CC

    We talk a lot about the ability to 'downsample' GH4 filmed in-house in 4 k at 1080 p and the advantage of it is 4:2:0 to 4:4:4. But he talked a lot about HOW better to do it using Adobe first Pro CC (or other software). So, how is this work exactly? I guess simply put a 4 k hit on a 1080 p timeline dimensionnera just, right? So, how can we get added advantage of color space? What are the steps to make this happen when editing with Adobe Creative Suite. Thank you!

    The GH4 puts 4 k - 10 bit only through HDMI out, not by internal record. So... the real after complete Assembly 10-bit 4:4:4 1080 p to get out 4 k - 10 bit 4:2:0 and then in transcoding in 1080 p, it can be left whole 1080 10 bit 4:4:4 through a 'natural' trans-mogrification of the additional data luma to color data. I saw the wonderful scientific discussions about this, Yes, it works that way. Leaves entire bt-10 4:4:4.

    A slight problem at the moment... There is apparently no portable recorders, which can record the range of the framerates the GH4 shoot at 4 k - 10 bits. A very expensive perhaps, but nothing to say Atomos those. So... IF you also Panny the YAGH (or "brick") unit attached to your GH4, with how it converts HDMI to SDI outputs, AND you happen to have a recorder SDI-connectable with any 4 k/10 bits-framerate capacity sitting there, you can get your film GH4 in a great for delivery edition wrapper.

    I've also seen the scientific discussion as to why take 4 k - 8 bit 4:2:0 and transcoding to 1080 p gets some improvements in the depth of color... data roughly equivalent of bits of 8.67. As one person has noted, as it is not an arithmetic scale is always a significant improvement of 'depth' of color data. More than 8 bits, but nowhere near the 10-bit.

  • How to extract information from tree logical structure using the PDF Library?

    How to extract information from tree logical structure using the PDF Library?

    Adobe's PDF Library has PDSEdit APIs to extract information of the logical structure of a tagged PDF file.

    But I couldn't find any example code to demonstrate the C API on PDSEdit layer.

    I google search using different keywords, find none.

    I contact datalogics (which gives me the evaluation of adobe PDF library copy), no code sample on APIs PDSEdit yet.

    Everyone knows any code example can demonstrate extract structure logic tree information PDSEdit APIs (in C/C++ or Java)

    from a tagged PDF file? And is there any sample to demonstrate that connects a tagged logical tree contained in the content stream?

    I thank very you much in advance!

    Did you look at the code snippets in the SDK?  There are a bunch of samples to work with PDSEdit and structure/marking.

    How can I add white space between areas that contain text fields?

    I use Adobe Acrobat Pro DC 2015.

    I'm trying to change an existing PDF. I need to add white space between areas that contain text fields to allow these areas to be developed and do not overlap the text and the text below fields.

    For example:

    1. 1.

    Progress/strategies:

    1. 2.

    Progress/strategies:

    1. 3.

    Progress/strategies:

    1. 4.

    Progress/strategies:

    The space between each 'progress/strategies' increasing needs. A text field is under each of them. If it's a Word doc, I could just press on enter. What is the best way to do this with Adobe Acrobat Pro DC?

    There is no easy way to do it. You need to move the text fields more apart and if there are static elements, then you will need to use the tool edit text & Images to move them, separately.
