Titanium Native Module (Android) and libraries for generating PDF files based on HTML
- The Android module has been tested with Titanium SDK 5.x and up.
- All the PDF creation is done by iText: http://itextpdf.com
iTextG, which is a port for AndroidXMLWorkerwhich is intended for parse HTML files into PDF- Important:
XMLWorkerdoes not support the whole subset of CSS styles, for the suppoerted list refer to their docs - iTextG is licensed under
GNU Affero General Public License version 3and depending on the nature of your app you might need a license. Please visit license for details.
- Go to the Releases Tab.
pdfGeneration.jsis optional to use, it contains the basics for generating a PDF file.pdfGeneration.jsdepends on mustache.js for parsing templates.
- For iOS, NappPDFCreator is recommended
##PDFCreator Module
-
Make sure you have the module dependency added on
tiapp.xml<module platform="android">com.propelics.pdfcreator</module> <module platform="iphone">dk.napp.pdf.creator</module>
-
Require the module(s) where needed
var PdfCreator = require('com.propelics.pdfcreator');
-
The usage of the module is based on events:
completeanderror.complete- Triggered once the PDF has been generated and no errors occured.error- Triggered if some error happens, stops the generation of the PDF.
-
The actual PDF creation can be achieved by the methods
generatePDFWithHTML()orgeneratePDFwithWebView()generatePDFWithHTML()- Parses some HTML string and creates a PDF file from it. UseXMLWorkerfor it. PDF files have the best quality but not all HTML/CSS properties are supported yet.generatePDFwithWebView()- Takes a screenshot from a givenTi.UI.WebViewand divides the resulting image into several pages. PDF files have medium quality and use a lot of space on disk, but supports all the HTML/CSS properties available.
var PdfCreator = require('com.propelics.pdfcreator');
PdfCreator.addEventListener("complete", function (_evt) {
//Handle the PDF created
var pdfFile = Ti.Filesystem.getFile(Ti.Filesystem.applicationDataDirectory, _evt.filename);
//...
});
PdfCreator.addEventListener("error", function(_evt){
//An error has ocurred
});
// Generate a PDF based on HTML
PdfCreator.generatePDFWithHTML({
html : '<html><body><h1>Hello World!</h1></body></html>',
filename : 'hello.pdf'
});
//Generate a PDF based on a webview
var webview = Ti.UI.createWebView({
scalesPageToFit : true
});
webview.addEventListener('load', function (e) {
PdfCreator.generatePDFwithWebView({
filename : 'hello.pdf',
webview : webview,
quality : 100
});
});
webview.url = 'www.apple.com';- This lib is intended to handle the common use cases for the PDF module creation. Therefore it depends on the
PDFCreatormodule. - Add
pdfGeneration.jsandmustache.jsunderapp/lib(for Alloy projects). - 2 functions are included to generate the PDF files
generateWithWebView()- Generates a PDF file based on an HTML File using a webview to load it's data. It does NOT usePDFCreator.generatePDFwithWebView()generatePDFWithTemplate()- Generates a PDF file based on an HTML Template, will load usingmustache.js
- Both functions take a set of options to generate the PDF.
htmlFile- File object to load that includes the HTML file to parsedata- Dictionary with data to be parsed inside the HTML before generating the PDFsucessCallback- Function called when the PDF gets generatedfailCallback- Function called if an error occurs
var PdfGeneration = require('pdfGeneration');
// Workaround to load images
var imageFile = Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, 'image.jpg');
var imgTemp = Ti.Filesystem.createTempFile();
imgTemp.write(imageFile.read());
PdfGeneration.generateWithWebView({
// Name of the PDF file to create
pdfFileName : 'webview',
// File containing the html to load
htmlFile : Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, 'webview.html'),
// A view to contain the Webview (should be inside an opened Window)
wrapper : $.index,
// Data to parse
data : {
customerName : 'John Doe',
image : imgTemp.resolve().replace('file:', '')
},
successCallback : function (_data) {
// The PDF was created
},
failCallback : function (_data) {
// An error occured
}
});
PdfGeneration.generatePDFWithTemplate({
// Name of the PDF file to create
pdfFileName : 'template',
// File containing the html to load
htmlFile : Ti.Filesystem.getFile(Ti.Filesystem.resourcesDirectory, 'template.html'),
// Data to parse
data : {
customerName : 'John Doe',
image : imgTemp.resolve().replace('file:', '')
},
successCallback : function (_data) {
// The PDF was created
},
failCallback : function (_data) {
// An error occured
}
});- In order to load images, the absolute path for the images is needed under the
srcattribute. - CSS styles should be loaded within the HTML file.
- Only the system fonts are supported. If the
font-faceincludes an specific name, it will take more time to load that usingseriforsans-serif
