• Rh10 Fm conversion with references to PDF with page number

  I have a FM document with images that are references to PDF with page number. After I do the conversion, by simply using the default settings/mappings, I get a HR document with the first image to reproduce throughout the document where the other images should be.

  What should I do to get the correct images converted?

  The class author template we created duplicate ID. The ID did not cause other problems other than with the conversion. The fix has been applied to the model so all is working now.

• ISO 3200 - 7.5.8 flow cross reference

  Hello

  I cannot interpret the example 4 on page 48 of the PDF 32000-1: 2008, specifically regarding the blue bold text below.

  The first field in these entries is the entrance type (2) - what is represent it 2?

  Item number stream (15) - what is represent it 15?

  
  

  position in the order of objects in the stream (0, 1, and 2) object - what this refer to?

  
  

  It is not clear which is the 15 if it is the second entry?   Someone would be able to explain where these numbers come from?
  

  The following example shows the same objects in the previous example, stored in the stream of an object in a PDF 1.5, as well as a stream of cross-reference.

  The cross-reference stream (see 7.5.8, "Reference Streams") contains entries for fonts (items 11 and 13) and the descriptor (item 12), which are compressed into the flow of an object. The first field in these entries is the entry type (2), the second field matches the number of the object stream (15), and the third field is the position in the order of the objects in the object stream (0, 1, and 2). The stream of reference also contains an entry of type 1 for the flow of the object itself.

  Refer to table 18 (7.5.8.3). The last 3 lines of this table describe what type (2), item (15) number and significance of the third field.

• E operator and horizontal scaling?

  I'll try to find an example of a PDF with horizontal scaling in one of it is the Tm.

  The other thing, I want to find is a pdf file with an operator used in Th.

  I think that I can't find anything on it it's because Th operator is used to create pdf files from scratch rather than the automatic writing of a pdf document from any file (using Adobe writer).

  My understanding is that if I have a Tm like that.   12 10 20 36 0 99

  and I have an operator of text fonts showing this:

  / F2 1

  the horizontal scale would then 20 x 1 = 20.

  But if that's the case then why a pdf file will contain an operator of Th.  Maybe they do not.  I have yet to find an example of one?

  Also, the my assumptions are correct on the horizontal scale above?

  My colleague and I try it worked, so we can incorporate this into our analysis tool pdf we write used in our workplace?

  An' th' is not an operator but a state parameter, which is initially set to 100. If a Tz operand is called, it will simply change the value of Th (level100).

  So you will never find a PDF document that uses a 'Th' operator because it is not defined (see "appendix table A.1: PDF content stream operators ' in the format PDF 32000-1: 2008).

• The hierarchical analysis of a document

  I am trying to create an outline/index for a document. In Acrobat, I see all the chapters and subsections in here. I want to reproduce it in the code. My platform is OS X so I use CGPDF calls *.

  What I have done until now is the following:

  • I take the documents catalog
  • Then I take the dictionary of contours
  • Because now I'm just looping in dictionaries of high level, starting with Outlines.First and then watch the next up next is not available

  Dictionaries contours, I take A entry. This dictionary contains S and D. I see S if type Name is "GoTo" and D is of type String and contains values such as "01_Chapter_One_Foo".

  So I managed to grab the outline and I have two titles and internal names for the chapters.

  What I don't understand is how to translate the 01_Chapter_One_Foo to index page. Is there a dictionary that contains this mapping or should I could parse the entire document to find an element with this value?

  S.

  You want to look at the section of the Reference/ISO PDF 32000-1 on "named destinations".

  Hi ToM,

  Yes, an object name can be an empty string (PDF 32000-1: 2008 - 7.3.5):

  The SOLIDUS (slash followed by no regular character) token introduced a valid unique name, defined by the empty character sequence.

• Cross reference flow problem

  Hello

  I try to develop a PDF parser, but I'm stuck at the stream of cross-reference.

  First of all, my program reads all the objects in a PDF document, and then saves it.

  If the version is 1.5 or superior, the cross-reference is an object that uses the filter FlateDecode and a predictor of 12.

  Everything seems to be good, but the PDF reader cannot open the file.

  When I save the file with a normal cross-reference, the PDF works fine.

  Can someone please help me find the problem in the following file:

  Download

  The file above is the result of the following file:

  Download

  With a normal cross reference table, therefore this file (work):

  Download

  Note that the difference between 1 and 3 is only at the end, where the dealer or the purpose of the xref.

  I checked the table of cross references again and again, but I could not find the error.

  Thanks a lot for your help!

  13 + 1 would be better

  The specification also says: 7.5.4 [...] For a file that has never been updated incrementally, the reference section contains only one paragraph, one object numbering starts at 0. [...]

  If you follow it, you must also not the Index Entry, or?

  Could you show me the results of your current work?

  See you soon,.

• Most common PDF Reference Manual here is no longer available?

  Hello!

  It's been a while since I needed to work with the PDF.  The latest version of the PDF reference manual is no longer available as a free download from the Adobe Web site?  Instead, I have to go buy it from the ISO web site?

  Thank you!

  There is a free version of the standard, ISO 32000-1: 2008 standard available on the Adobe site.

• Can I change a cross-reference without having view to recreate it?

  When the cross refer to the numbers on the same page, I leave the cross point to unique reference numbers ("see view 25"). When it is on another page, I use the paragraph and page numbers ("see 25 page 34"). But when my text changes, sometimes text moves, sometimes move the images and I need to change the cross-reference. It's quite annoying, I have to old rmeove and create a new one in the hunt for the removal of a list of 150 or more.

  Is there a simpler way? For example, put the insertion point in the cross reference, then an easy way to choose a different look?

  There is reference to updated and re-issued reference of choice in the hyperlinks Panel menu. Have you tried those? You can also change the formatting of a reference in Cross Reference Options.

• Using cross-references in the index?

  I was wondering if there are any suggestions out there for using cross-references in the index.
  
  I don't think you use the option 'see also' is what I'm looking for; what I want to do is to create index with a cross next to them reference entries.
  
  I tried this by creating an entry index and typing (see "another name of the topic") next to it, but when I compiled the project that this index entry has not been included because I do not have a subject entrusted to him.
  
  Is it possible to create an index entry of reference without an assignment of subject? Or are there other workaround solutions that you use?

  Index of cross-references are designed to allow you to have keywords in the index when you click on redirect the user to another keyword. For example I use for acronyms to redirect users to the long version. You are subject cross references within the project? If so, you may not use the index of references by indexing the same way? If the cross-reference you want is outside the project, using the index is not the way I would say. Why not use a link in a topic to a URL, file, etc. You may be able to do what you want with a redirection topic, but I haven't looked into this. Come back with more details if I leave the brand.

• content stream

  Hello

  When a content of the page consists of a table of flow, is it valid to split a resource name in the stream?

  Example of a valid workflow:

  Stream 1:

  < start Stream >

  ....

  / F143

  < end flow >

  Stream 2:

  < start Stream >

  1 Tf

  ...

  < end flow >

  But is it valid?

  Stream 1:

  < start Stream >

  ....

  / F14

  < end flow >

  Stream 2:

  < start Stream >

  3 1 Tf

  ...

  < end flow >

  Should Acrobat also manages the second example and understand the full stream "... F143 1 Tf..."?

  PDF reference there is character delimiters said but it seems when < end flow > is reached, the name of the resource is considered complete (what would be reasonable, I just need to know for sure if I can handle PDF files like this even if I don't expect to see a such PDF often).

  Polda

  -Perfectly valid Yes!   It is said in the standard (ISO 32000-1: 2008) water courses are considered to be a single merged stream (with an added single whitespace character between).

• 'Convert pdf to Excel' vs 'export pdf to Excel.

  In the new subscription CD, the option of PDF conversion options ($ 1.99 / month) says we can "Convert pdf to Excel", while the PDF package option ($ 7.99 / month) says you can "export pdf to Excel.  What is the difference between 'Convert pdf to Excel' and 'export pdf to Excel?

  'Marketing' talk.

  Is the file being developed 'PDF' and PDF format published by Adobe for ISO a few years ago.

  In the Adobe PDF Reference documents and now in ISO 32000-1: 2008 (and the following; 'Part 2') 'export' PDF is described - not "convert".

  Factually, it would be 'export '. So 'convert' seems to be a malignant fever of marketing.

• fgetc reports ' argument open stream ", the fopen() function succeeded

  Hello

  I'm looking to implement the GNU 'getline()' function in CVI and the function starts as:

  getline.dll:

  Ssize_t getline WINAPI LIBAPI (char * lineptr, size_t * n, FILE * stream) {}

  int c;

  While (TRUE) {}

  c = fgetc (stream);    Error occurs here

  ...

  }

  }

  (LIBAPI is DLLEXPORT or DLLIMPORT). It is then compiled as a DLL and put it somewhere in the world. Then I have another DLL that does this:

  Driver.dll:

  int ReadWaveform (void) {}

  FILE * fwave;

  char * lineptr = NULL;

  int n = 0;

  fwave = fopen ("waveform.txt", "r");

  Len = getline (& lineptr, & n, fwave);

  ...

  }

  I get the error "Argument must be an open stream" when the 'fgetc()' function is called. It does not produce an error if this fgetc() is put in the ReadWaveform() function. The file exists, it is readable (the permissions of files are read-only, but read/write changes its behavior either). The two libraries are compiled in debug (or the getline.dll has also been compiled as a liberation, but does not change because the file can not be read and fgetc() reports EOF immediately that it should in case of error).

  So there seems to be some issues to limit cross-DLL when using file streams if open the stream in the DLL driver.dll and work with her in getline.dll. I did not have this problem with other C languages.

  any help on this would be appreciated. I use CVI 9.0 on Windows XP.

  Thank you

  Jason.

  I think this problem is the same as malloc/free deliver you in the other thread. Basically, I think that your two dll is built with runtime different support options, and so, engine running different CVI DLLs are called to manage resources. If you build your dll/program with the same runtime support option, then you should be able to share the FILE pointer through modules - you can't always do it for other reasons of design.

• My mind is wiped out. I'll put up pages in Photoshop 9.0 to be then placed in InDesign 4.0 for professional printing. Can you help me configure the proper color settings, and what PDF preset to use. And output parameters, etc. Thanx.

  My mind is wiped out. I'll implement the color pages in Photoshop 9.0 to be then placed in InDesign 4.0 for commercial printing in book form. Can you help me with the settings of color in Photoshop, that is to incorporate the color profile; convert in space work, Adobe RGB, etc. and which PDF preset to use, i.e. printing, PDF / X - 1 or 3, etc. Also, what I have to select the output settings such as the conversion of colors with the Destination or the printer deals with that. I know I asked a lot, so thanks in advance for any input or advice.

  Best regards, ScottyB34

  What are the settings of your printer wants? Some may deal with sRGB some want Adobe RGB Ctrl/Cmd-Shift-k in Photoshop, then choose North Amercian prepress 2

  He'll take care of the tags for you, or if sRGB is important, Norh American General Purpose 2.

  Here is a summary of the settings PDF and their meaning:

  When you are ready to create a PDF file from an application such as Illustrator or InDesign Adobe, we give you a list of the predefined PDF settings from which to choose. Well how do you decide which is the right choice? Well, let me explain what they do.

  Let's start with the smallest file size and the name of the type of the story. It is compatible with Acrobat 6, which means that anyone who has Reader or Acrobat 6 or above will be able to open the file. Now it converts everything in sRGB color which is a common space for color monitor.

  All RGB is truncated to sRGB, CMYK and spot colors also. So that means if you have a job to print, you can see some color shifts in this outgoing PDF. You must decide whether it is acceptable. He can't stand live transparency, not flattened. It downsize image content to 100 pixels per inch and this is part of how she made a reduced file size. It also uses aggressive JPEG compression of poor quality on the content of the image. So, you can see some of these rectangular JPEG artifacts.

  But it is how it gives you a reduced file size, and results are appropriate to be posted online or attached to an email.

  High quality printing has compatibility with Acrobat 5 and above. There is no color conversion. RGB RGB stays, rest spot, stays of CMYK CMYK spot and it supports live, not flattened transparency. It does not perform some downsampling to 300 pixels per inch. So, for example, if you placed an image which was 300 ppi and then set to scale up to 50 percent there actually a res then 600 pixels per inch.

  Well, this process would take half out these pixels. Therefore, it can create larger files but that makes it suitable for in the House of printing or sending Let's say a remote office if they want to print we tell cells leaves, or brochures, or something like. It's beautiful out on an internal printer.

  Print quality and high quality printing have similar names, so this may be a bit confusing, but print quality has compatibility with Acrobat 5 or higher. It converts the content of RGB to CMYK destination values according to what you specify as the destination.

  It is usually SWOP, S-W-O-p. It supports live, not flattened transparency. It performs the subsampling bicubic to 300 pixels per inch and because that it keeps at least 300 pixels per inch, which means that it can create some large files, but it is suitable for professional printing.

  Then we start to get into the presets named 'X '. 'X' is now for Exchange. They agree on specifications and the idea is to have a set of specifications if a PDF file is compliant to these specifications, we know it's going to be printable.

  We know that imaging devices are going to treat them properly. So this goes back to 2001, and which can seem a bit old, but bear with me. PDF/X-1 has a compatibility with Acrobat 4. I know, it sounds old. It converts RGB to CMYK content, it keeps the content of good tones. It flattens transparency. Downsize it at 300 pixels per inch. It can large enough crat files if you have large size images in your project and that it is suitable for professional printing.

  The idea behind X-1 is if you send a PDF file to an unknown printer, you do not know what are their capabilities, you send abroad, it will be able to be photographed on any device. No matter the age, it is, they can print. Over the years, the concepts of Exchange became more sophisticated the workflow and devices become more sophisticated.

  SP PDF / X-3: 2002, remains compatible with Acrobat 4 and that means that it flattens transparency, but it does not perform any color conversion.

  This means that it maintains RGB content, place remains in place, rest of CMYK CMYK. He still performed bicubic downsampling at 300 pixels per inch, and therefore, it can create large files. But this is suitable for commercial printing, if the printer signals you that it is present RGB content is correct.

  PDF / X-4: 2008 is compatible with Acrobat 7 and later. See, we're getting more modern. No color conversion. RGB RGB stays, stays CMYK CMYK, spot rest spot and it supports live, not flattened transparency.

  He still performs bicubic downsampling. Therefore, it can create large files because it maintains the pieces of the image to 300 pixels per inch or higher and it is suitable for commercial printing, as long as the printer tells you that RGB content is not serious and dynamic transparency is acceptable. Some older workflow does not support dynamic transparency, or they treat well, and that's why always ask. It is a special case in Illustrator, something called default Illustrator. Its compatibility is Acrobat 6 or higher.

  It does not perform the color conversion, everything continues like this. It supports transparency live, not flattened, and it also contains the original, editable Illustrator file in the PDF file. It preserves layers and it may be return, can be reopened safely in Illustrator and it's really the only PDF format you can do with safely. But it can create larger files, because you sort of two files for the price of one, they sometimes get huge.

  So what predefined PDF is Right For You? Well, if you want to send for printing, the first thing you should do is to ask your printer how they want the created PDF.

  They should be able to give you the plug for the creation of the PDF file. They may be able to give you job options files you can simply import and use as your preset target. But if it's a stranger the printer or the printer for some reason any said, well, I don't know, just make a PDF and this happens, well, choose the lowest common denominator to the PDF/X-1 test. Anyone can image that. If it is a more modern printer and up to date, especially if you send it to someone who uses digital presses, PDF/X-4 should be safe.

  I always go back to point one, ask the printer. If you send it as an attachment or you're going to post online, well, smaller size of file is a pretty clear choice. But remember this, you can start with one of these predefined parameters, and you can always edit it to customize your specific needs. So get to know the presets, understand the destiny of the PDF you create, and then make the best PDF that you can.

• I need to convert a PDF file to Excel every day at work.

  When I do, it changes some of the formatting on a daily basis where I have to re-enter all the headers.   I do something wrong when I export the PDF file? Thank you!

  PDF (format / technology defined and described in the standard PDF ISO, ISO 32000-1: 2008) isn't like a processor or format worksheet.

  There is no 'columns', 'rows', 'styles', "formats", etc.

  Content objects are painted on the PDF page. According to just what is used to create the PDF file, this process can be a bit like a random painting by numbers in terms of content case which is painted when.

  To optimize the export from a PDF file, you need a well-trained marked PDF (ISO 14289-1, PDF/UA-1 compliant PDF).

  Two key design of the tagged PDF document considerations are (1) Accessible PDF & (2) export of content to the file formats supported.

  Without this well-trained marked PDF your exports will be what you have seen.

  What should do? You must use Excel to clean the XLS content. (or print PDFS on paper and transcribing paper in a new fresh XLS file).

  Be well...
