query while working with PDPageNode using pdfBox - 


  दस्तावेज़ = PDDocument.load (filePath); System.out.println ("पृष्ठ संख्या =" + document.getNumberOfPages ()); PDDocumentCatalog docCata = नया PDDocumentCatalog (दस्तावेज़); मानचित्र के & lt; स्ट्रिंग, पूर्णांक & gt; Pmap = document.getPageMap (); System.out.println ("count =" + pmap.size ()); // यह गिनती = 562 pnode = docCata.getPages () प्रिंट करता है; KidList = pnode.getKids (); System.out.println ("बच्चे की सूची का आकार =" + kidList.size ()); // यह बच्चे के आकार का भी छापता है = 0 // सिस्टम। आउट.प्रिंटलैनी(--------size= "+ pnode.getRotation ()) // नल सूचक अपवाद फेंकता

नमस्ते मैंने ऊपर कोड के साथ काम करने की कोशिश की, हालांकि मैं बच्चों को pnode.getKids का उपयोग करने में सक्षम नहीं हूं।

उपरोक्त निम्नलिखित आउटपुट देता है: 

  पन्नों की गणना = 562 गिनती = 562 बच्चा सूची का आकार = 0

पीडीएफ के पन्नों पर भी जब बच्चे की आबादी नहीं आ रही है तो मुझे नहीं मिल रहा है कृपया इस संदर्भ में कुछ सहायता प्रदान करें।

धन्यवाद।

अधिकतर आप चाहते हैं करने के लिए 

  PDDocumentCatalog docCata = document.getDocumentCatalog ();

के बजाय 

  PDDocumentCatalog docCata = नया PDDocumentCatalog (दस्तावेज़);

getDocumentCatalog () मौजूदा दस्तावेज़ कैटलॉग को पुनर्प्राप्त करता है जबकि नया पीडीडी दस्तावेज़कॉक (दस्तावेज़) किसी भी पेज के बिना एक नया बनाता है।

php - Select box validation (in laravel) -

I have a text that includes text input and selection box. I was trying to apply Laravel validation. I now want to retain user input values ​​if the verification does not succeed. I'm able to get it on the input box, but not on the selection box.

What I do is that I add the "default" option which is "nothing" Is set to. In the validity rules, I say this value is necessary. If the user does not choose any of the other options, the verification fails. $ op...

Creating a sparse matrix in Matlab with a specified number of independent Bernoulli +-1 nonzero entries -

How can we create matrix x, 1000 by 1000 in the matteback, which is sparse, say Are, 5% of independent Bernoulli + 1 nonzero entries? I.e. In such a matrix, rho = = X Choose 5% of irregular elements n = Numel (x); Ind = Randie (n, round (.05 * n), 1); Assign these elements with random variables x (ind) = binorend (1, .5, length), 1) * 2-1; Check for more information To prevent duplicate rand numbers, from the Statistics Toolbox, or randperm as mentioned in some, or something like this Ind = []; T = round (.05 * n); T1 = length (IND); While T1 & LT; T Ind (end + 1: t0) = rand (n, tt-1, 1); Ind = Unique (Ind); T1 = length (IND); End
