How difficult problem in pdf solved by just creating it

Yes! in programming the thing that gave me blow was creating PDF having URL images.

I Used lot of methods for it but all were with some corns and pros. e.g if you are able to load replica of table on PDF then problem was with loading URL images e.g amazon S3, google images etc. Here i will describe you what technology i used what methods i applied for generating pdf.

TECHNOLOGIES:

JavaScript(Client Side), NodeJS (Server Side)

METHODS or PACKAGES:

jsPDF, PDFMake, PDFkit

DESCRIPTION ABOUT TECHNOLOGIES AND PACKAGES:

As using these technologies and methods I have some points that will help you to use efficiently

  • Using jsPDF and PDFMake You can generate PDF file having static data and images easily.
  • When it comes to URL based images it become difficult to load directly to PDF file we can load images to PDF file by using some JavaScript methods like canvas which first use URL images as its function parameter then convert it into Base64 string which then can be used by jsPDF or PDFMake’s methods
  • Now if we have images and table’s data both but there will be another problem of converting numbers of images to base64 and it is hang of application.
  • So i found a way for converting PDF file is the PDFkit. it is the practice to converting PDF file, the only thing that it requires is hit and trail, the method that best for it according to me is PDFkit as mentioned. it all requires server side support like file system, request packages e.g var fs = require(‘fs’), var request = require(‘request’) ;
  • Request method basically overcome the base64 issue what it does it take image URLs and make it buffer the pdfkit used that buffer data and load it to PDF page without hanging application. pdfkit even support many properties like decorating text with font property, geometries like line, triangle, square and many all you just need apply hit and trial and you will get almost same table with dynamic images example you want to create pdf for vehicle inspections .

TIP:

The more math you have, the more fast you are.
