When performance of the local ColdFusion Server is critical as PDF generation is a CPU intensive operation.When the ColdFusion Server is running on an OS not supported by the local PDF service manager.You may need to use a remote PDF service manager instead of the local PDF service manager, if any of the following are true: If you choose to install support for PDF generation during ColdFusion installation, a local PDF service manager (the “add-on service”) is installed. On RHEL 8, you can install the following packages:įor instance, you can use yum to install these packages as shown below: Performs HTML to PDF conversion in process.Encapsulates the PDF conversion library.The component running inside the Jetty server is referred as the service manager, which takes request for PDF conversion from one or many ColdFusion server/s. The WebKit implementation for is referred as PDFG (acronym of PDF Generator) which is shipped as part of the Jetty installer. creates high quality PDF output from a text block containing CFML and HTML using the PDF Service Manager. In your browser, open website http :///xorg/font/ibm-type1/ĭownload the compressed filefont - ibm -type1-1.0.3.tar.gz or font- ibm -type1-1.0.3.zip.The compressed file contains the required fonts.Įxtract the downloaded zip file to the/usr/share/fonts directory.To install the fonts, perform the following tasks: On Linux platforms, install the following additional packages:įor instance, you can use yum to install these packages as shown below:Īlso, you need to install a few required fonts for generating PDFs on Linux. On Linux, ensure that the following additional requirements are met: Additional package requirements On Windows, there are no additional requirements for generating PDFs. PDF generation is supported on both Windows and Linux operating systems. WebKit - Is a layout engine software designed to allow web browsers to render web pages.Service Manager - Manages the PDF generation service processes, monitors the service process states, spawns new processes for conversions, and facilitates recycling of processes.Service - Refers to the process which carries out series of activities to convert HTML documents to PDFs.The following terms are the commonly used in (WebKit): This document describes the usage and functionalities of these tags. If found, indicate which section of code need to have a page break inserted before it, and then reproduce the report.To generate high quality PDFs from HTML documents, use the tags and. Once the PDF file has been created, use Raymond's pdfutils to check each page for a start without a matching end. Keep_together_end_#NumberFormat(keep_together_count,"000")# Keep_together_start_#NumberFormat(keep_together_count,"000")#Īt the end of the section to be kept together On initialisation of the page that creates the pdfĪt the start of a section of output that I want kept together, put the following If the matching start and end tags are not on the same page, then the pdf is recreated with an appropriate page break prior to the section to be kept together. Keep_together_start_001, keep_together_end_001, keep_together_start_002, keep_together_end_002 etc It creates hidden fields in the pdf, formatted as Others may like to embellish the following. It is not overly efficient, in that it recreates the entire report for each instance whereĪ page break needs to be repositioned, but the preliminary testing is good. This has enabled me to do a workaround fix for the problem where cfdocument does not support The zip includes 2 PDFs, the component, and my test script. And what's cool is that if your intent is to get the text out for searching/indexing purposes, you can still find it useful. When the method is run on this PDF, the text does come back, but it is a bit crazy looking. Ok it isn't wacky looking per se, but it isn't a simple letter. The other one is a highly graphical, wacky looking PDF. As you can imagine, the function works great with it. I've included on this blog post two sample PDFs. Each item in the array is the text on that particular page. You pass in the path to a PDF and you get an array of pages. Right now the CFC has one method, getText. For those who thought it might be too difficult to use the DDX, I've wrapped up the code in a new ColdFusion Component I'm calling PDF Utils. One of the cooler examples was that DDX could be used to grab the text from a PDF file. Yesterday I blogged about ColdFusion and DDX, a way to some fancy-pants neato transformations of PDF documents.
