I am using itext-5.3.4.jar and xmlworker-1.2.1.jar library for generate pdf from html string , html contains image logo and inline css.
My html file and image is in Asset folder , using this library my pdf generating successfully but there is no image display and no css style randering. anyone has a suggestion what should i do to fix this issue, if any other library or any other option for generate pdf from html will be helpful.
I am using these function for generate pdf:
public static void generatePdfFromHtlm(String fileName, String htmlString){
try {
File mediaStorageDir = new File(Environment.getExternalStorageDirectory(), AppConfig.getContext().getPackageName() + "/" + "Pdf");
if (!mediaStorageDir.exists()) {
mediaStorageDir.mkdirs();
}
File fileWithinMyDir = new File(mediaStorageDir, fileName);
FontFactory.registerDirectories();
Document document = new Document(PageSize.A4);
PdfWriter writer = PdfWriter.getInstance(document,
new FileOutputStream(fileWithinMyDir));
document.open();
HtmlPipelineContext htmlContext = new HtmlPipelineContext(null);
htmlContext.setTagFactory(Tags.getHtmlTagProcessorFactory());
htmlContext.setImageProvider(new AbstractImageProvider() {
public String getImageRootPath() {
Uri uri = Uri.parse("file:///android_asset/");
String newPath = uri.toString();
return newPath;
}
});
CSSResolver cssResolver =
XMLWorkerHelper.getInstance().getDefaultCssResolver(false);
/*Pipeline<?> pipeline =
new CssResolverPipeline(cssResolver,
new HtmlPipeline(htmlContext,
new PdfWriterPipeline(document, writer)));*/
// Pipelines
PdfWriterPipeline pdf = new PdfWriterPipeline(document, writer);
HtmlPipeline html = new HtmlPipeline(htmlContext, pdf);
CssResolverPipeline css = new CssResolverPipeline(cssResolver, html);
XMLWorker worker = new XMLWorker(css, true);
XMLParser p = new XMLParser(worker);
InputStream is = new ByteArrayInputStream(htmlString.getBytes());
p.parse(is);
document.close();
} catch (Exception e) {
e.printStackTrace();
}
}
my html file is

I have Fixed Pdf Generate Issue With Xml Worker class.
For overcome CSS issues i have create external css file and apply it with the html.
For ex.
InputStream is = new ByteArrayInputStream(aHtmlString.getBytes());
InputStream css = new ByteArrayInputStream(cssString.getBytes());
XMLWorkerHelper.getInstance().parseXHtml(writer, document, is, css);
For Image Display issue copy your image From assets folder to phones internal folder.
Add give your img tag to that folder image path.
For ex.
<img src="/storage/emulated/0/MyApp/Images/my_logo.jpg"/>
Use This methods for copy files from asset to folder.
public static void listAssetFiles(String path,Context ctx,String folderPath) {
String [] list;
try {
list = ctx.getAssets().list(path);
if (list.length > 0) {
// This is a folder
for (String file : list) {
copyIntoFolder(file,ctx,path+"/",folderPath);
}
}
} catch (IOException e) {
}
}
public static void copyIntoFolder(String fileName, Context ctx, String filePath, String folderPath){
AssetManager assetManager = ctx.getAssets();
InputStream in = null;
OutputStream out = null;
try {
in = assetManager.open(filePath+fileName);
File outFile = new File(folderPath , fileName);
out = new FileOutputStream(outFile);
Utility.copyFile(in, out);
in.close();
// in = null;
out.flush();
out.close();
//out = null;
} catch(IOException e) {
Log.e("IOException", "copyIntoFolder: ",e );
}
}
Itext doesnt support all css properties below is a list of suported css properties, create your html according this supported css properties.

iText Sharp is not supported all css property.You can load html in webview and generate pdf using this code.
private void createWebPrintJob(WebView webView) {
try {
PrintDocumentAdapter printAdapter;
String jobName = getString(R.string.app_name) + " Document";
PrintAttributes attributes = new PrintAttributes.Builder()
.setMediaSize(PrintAttributes.MediaSize.ISO_A4)

File path = new File(Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/AamirPDF/");
path.mkdirs();
PdfPrint pdfPrint = new PdfPrint(attributes);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
printAdapter = webView.createPrintDocumentAdapter(jobName);
} else {

}
pdfPrint.printNew(printAdapter, path, "output_" + System.currentTimeMillis() + ".pdf", getActivity().getCacheDir().getPath());
