We are using bcl easy pdf sdk 8 to convert files. Except excel and html all other files I could convert. I am getting error as "error converting to pdf, failed to create a pdf rendition". Do any of them have experienced in this Easy PDF software. Please help me on this.
Regards,
sudha
I think you are using a not right method of conversion.
Please see the code below for easy PDF SDK (C#):
Excel to PDF
using BCL.easyPDF.Printer;
namespace TestPrinter
{
class Program
{
static void Main(string[] args)
{
if(args.Length != 2)
return;
string inputFileName = args[0];
string outputFileName = args[1];
Printer printer = new Printer();
try
{
ExcelPrintJob printjob = printer.ExcelPrintJob;
printjob.PrintOut(inputFileName, outputFileName);
}
catch(PrinterException ex)
{
System.Console.WriteLine(ex.Message);
}
finally
{
printer.Dispose();
}
}
}
}
HTML to PDF
using BCL.easyPDF.Printer;
namespace TestPrinter
{
class Program
{
static void Main(string[] args)
{
if(args.Length != 2)
return;
string inputFileName = args[0];
string outputFileName = args[1];
Printer printer = new Printer();
try
{
IEPrintJob printjob = printer.IEPrintJob;
printjob.PrintOut(inputFileName, outputFileName);
}
catch(PrinterException ex)
{
System.Console.WriteLine(ex.Message);
}
finally
{
printer.Dispose();
}
}
}
}
Why don't you just contact their support team for an assistant?

I'm using the javascript SDK of Microsoft Speech Synthesizer and calling speakTextAsync to convert text to speech.
This works perfectly, but sometimes the text is long and I want to be able to cancel in the middle, but I cannot find any way to do this. The documentation doesn't seem to indicate any way to cancel. The name speakTextAsync suggests that it returns a Task that could be cancelled, but in fact the method returns undefined, and I can't find any other way to do this. How can this be done?
Seems there is no way to stop it when it is speaking. But actually,as a workaround, you can just download the audio file and play the file yourself so that you can control everything. try the code below:
import com.microsoft.cognitiveservices.speech.*;
import com.microsoft.cognitiveservices.speech.audio.AudioConfig;
import java.nio.file.*;
import java.io.*;
import javax.sound.sampled.*;
public class TextToSpeech {
public static void main(String[] args) {
try {
String speechSubscriptionKey = "key";
String serviceRegion = "location";
String audioTempPath = "d://test.wav"; //temp file location
SpeechConfig config = SpeechConfig.fromSubscription(speechSubscriptionKey, serviceRegion);
AudioConfig streamConfig = AudioConfig.fromWavFileOutput(audioTempPath);
SpeechSynthesizer synth = new SpeechSynthesizer(config, streamConfig);
String filePath = "....//test2.txt"; // .txt file for test with long text
Path path = Paths.get(filePath);
String text = Files.readString(path);
synth.SpeakText(text);
Thread thread = new Thread(new Speaker(audioTempPath));
thread.start();
System.out.println("play audio for 8s...");
Thread.sleep(8000);
System.out.println("stop play audio");
thread.stop();
} catch (Exception ex) {
System.out.println("Unexpected exception: " + ex);
assert (false);
System.exit(1);
}
}
}
class Speaker implements Runnable {
private String path;
public String getText(String path) {
return this.path;
}
public Speaker(String path) {
this.path = path;
}
public void run() {
try {
File file = new File(path);
AudioInputStream stream;
AudioFormat format;
DataLine.Info info;
Clip clip;
stream = AudioSystem.getAudioInputStream(file);
format = stream.getFormat();
info = new DataLine.Info(Clip.class, format);
clip = (Clip) AudioSystem.getLine(info);
clip.open(stream);
clip.start();
} catch (Exception e) {
System.out.println(e.getMessage());
}
}
}
With the reference of following StackOverflow suggestion,
Convert HTML to PDF in .NET
I tried to convert the HTML file to PDF using HtmlRenderer.PdfSharp but unfortunately it shows compatible error like below,
HtmlRendererCore.PdfSharpCore 1.0.1 is not compatible with netstandard2.0 (.NETStandard,Version=v2.0). Package HtmlRendererCore.PdfSharpCore 1.0.1 supports: netcoreapp2.0 (.NETCoreApp,Version=v2.0)

And I tried with wkhtmltopdf too but it throws similar error in android and other platform projects.
My requirement is to convert the HTML file to PDF file only (no need to view the PDF file, just to save it in local path).
Can anyone please provide suggestions?
Note : Need open source suggestion :)
Awaiting for your suggestions !!!
Support to convert the HTML to PDF in Xamarin Forms
You can read the HTML as a stream and store it into local like below,
public static class FileManager
{
public static async Task<MemoryStream> DownloadFileAsStreamAsync(string url)
{
try
{
var stream = new MemoryStream();
using (var httpClient = new HttpClient())
{
var downloadStream = await httpClient.GetStreamAsync(new Uri(url));
if (downloadStream != null)
{
await downloadStream.CopyToAsync(stream);
}
}
return stream;
}
catch (Exception exception)
{
return null;
}
}
public static async Task<bool> DownloadAndWriteIntoNewFile(string url, string fileName)
{
var stream = await DownloadFileAsStreamAsync(url);
if (stream == null || stream.Length == 0)
return false;
var filePath = GetFilePath(fileName);
if (!File.Exists(filePath))
return false;
File.Delete(filePath);
// Create file.
using (var createdFile = File.Create(filePath))
{
}
// Open and write into file.
using (var openFile = File.Open(filePath, FileMode.Open, FileAccess.ReadWrite))
{
stream.WriteTo(openFile);
}
return true;
}
public static string GetFilePath(string fileName)
{
var filePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), fileName);
return filePath;
}
public static void WriteAsText(string filePath, string contents)
{
File.WriteAllText(filePath, contents);
}
public static string ReadAsText(string filePath)
{
return File.ReadAllText(filePath);
}
}
You can read a stored pdf file and displayed using webview like below,
private async void HtmlToPDF()
{
await FileManager.DownloadAndWriteIntoNewFile("https://www.google.co.in/?gws_rd=ssl", "SavePDF.pdf");
var filePath = FileManager.GetFilePath("SavePDF.pdf");
var pdfString = FileManager.ReadAsText(filePath);
var webView = new WebView
{
Source = new HtmlWebViewSource
{
Html = pdfString
}
};
this.Content = webView;
}
And the output below,
Likewise, you can save HTML as PDF and do what you want..
you can use the HtmlToPdfConverter
private void ConvertUrlToPdf()
{
try {
String serverIPAddress = serverIP.Text;
uint serverPortNumber = uint.Parse (serverPort.Text);
// create the HTML to PDF converter object
HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter (serverIPAddress, serverPortNumber);
// set service password if necessary
if (serverPassword.Text.Length > 0)
htmlToPdfConverter.ServicePassword = serverPassword.Text;
// set PDF page size
htmlToPdfConverter.PdfDocumentOptions.PdfPageSize = PdfPageSize.A4;
// set PDF page orientation
htmlToPdfConverter.PdfDocumentOptions.PdfPageOrientation = PdfPageOrientation.Portrait;
// convert the HTML page from given URL to PDF in a buffer
byte[] pdfBytes = htmlToPdfConverter.ConvertUrl (urlToConvert.Text);
string documentsFolder = Environment.GetFolderPath (Environment.SpecialFolder.MyDocuments);
string outPdfFile = System.IO.Path.Combine (documentsFolder, "EvoHtmlToPdf.pdf");
// write the PDF buffer in output file
System.IO.File.WriteAllBytes (outPdfFile, pdfBytes);
// open the PDF document in the default PDF viewer
UIDocumentInteractionController pdfViewer = UIDocumentInteractionController.FromUrl (Foundation.NSUrl.FromFilename (outPdfFile));
pdfViewer.PresentOpenInMenu (this.View.Frame, this.View, true);
} catch (Exception ex) {
UIAlertView alert = new UIAlertView ();
alert.Title = "Error";
alert.AddButton ("OK");
alert.Message = ex.Message;
alert.Show ();
}
}

My problem is printwriter method. I don't know why it doesn't save text from the console to the text file. It should work but the only line that is saved in the file is "quit". I `m new to Java and this forum. Hopefully, someone will be able to help me.
Greetings
Michal
public class Output3 {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String line= "";
try {
PrintWriter ska = new PrintWriter("trial1");
while(!linia.equals("quit"))
linia = scanner.nextLine();
ska.println(line);
ska.flush();
System.out.println("Message saved");
} catch(IOException e){
e.printStackTrace();
}
}
}
Have you seen that you read from the input stream through the variable linia and write data from the variable line to your file? Have you tried writing using the following line?
ska.println(linia);
I am using pdfbox to get the names of all fonts that are used in a pdf.
So far it was working well. However, I recently came across a pdf that has 'Webdings' font. PDFBox was not able to identify it.Could anyone help please.
This is the code I have used:
public static Set<String> extractFonts(String pdfPath) throws IOException
{
PDDocument doc = PDDocument.load(new File(pdfPath));
PDPageTree pages = doc.getDocumentCatalog().getPages();
Set<String> fontSet = new HashSet<String>();
try{
for(PDPage page:pages){
PDResources res = page.getResources();
for (COSName fontName : res.getFontNames())
{
PDFont font = res.getFont(fontName);
if(font != null){
String fontUsedName = font.getName();
if(fontUsedName.contains("+")) {
fontUsedName = fontUsedName.substring(fontUsedName.indexOf("+")+1, fontUsedName.length());
}
fontSet.add(fontUsedName);
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
System.out.println(fontSet);
return fontSet;
}
I was able to know that the font 'Webdings' is present from the File-> Properties->Fonts option in Adobe Reader
I'm trying to convert docx document to html, but I cant make encoding work well. OutputStream contains xml header with declaration that content is encoded with UTF-8 but instead of language specific signs (like: ąśćźż) I get some garbage. Here is my converter code:
public class DocumentProcessor extends DocumentProcessorInterface {
private WordprocessingMLPackage load;
private HTMLSettings htmlSettings;
private Http.MultipartFormData.FilePart filePart;
public DocumentProcessor(Http.MultipartFormData.FilePart filePart) {
super(filePart);
this.filePart = filePart;
}
private void prepare() {
try {
load = Docx4J.load(filePart.getFile());
htmlSettings = Docx4J.createHTMLSettings();
htmlSettings.setImageHandler(new DataUrlImageHandler());
htmlSettings.setWmlPackage(load);
} catch (Docx4JException e) {
e.printStackTrace();
}
}
#Override
public String getHTML() {
prepare();
OutputStream outputStream = new ByteArrayOutputStream();
Logger.info("Converting");
try {
Docx4J.toHTML(htmlSettings, outputStream, Docx4J.FLAG_EXPORT_PREFER_XSL);
} catch (Docx4JException e) {
e.printStackTrace();
}
Logger.info("Converted");
return outputStream.toString();
}
}
Output looks like this: http://imgur.com/0sTTIe6 I've already checked database encoding itself.
What have I missed?
As a #JasonPlutext suggested, I should create new string and set encoding to UTF-8.
return new String(outputStream.toByteArray(), "UTF-8");
and that is the answer for my problem.
