I want to print pdf file generated by itext. I also use PDFBox for this. At this page
PDFBox: How to print pdf with specified printer?
everything is explained, but I am having problem about page size. Original size of pdf file is 10x150 mm (3,93x5,9 inch). When I run the code the file is printed but not with its original size. My pdf file is printed at the noth-west of the page with nearly %70 decreased size.
Here is my code for this
public class LabelPrinter {
public LabelPrinter() {
}
public static PrintService getNamedPrinter(String name, PrintRequestAttributeSet attrs) {
PrintService[] services = PrintServiceLookup.lookupPrintServices(null, attrs);
if (services.length > 0) {
if (name == null)
return services[0];
else {
for (int i = 0; i < services.length; i++) {
if (services[i].getName().equals(name))
return services[i];
}
}
}
return null;
}
public static void printLabel(String fileName,String printerName) throws FileNotFoundException, PrintException, IOException, PrinterException{
PrinterJob job = PrinterJob.getPrinterJob();
PrintService myService=getNamedPrinter(printerName, null);
if(myService!=null){
job.setPrintService(myService);
PDDocument doc = PDDocument.load(fileName);
doc.print(job);
}
else{
System.out.println("printer not found");
}
}
}
I hope I could explain enough. (Accept my appologies for my bad English)

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 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
Anyone can help in this code, the pdf file is not loading in app and just showing blank white screen, Logcat showing FileNotFoundExeeption: /storage/sdcard/raw/ourpdf.pdf.
i am trying to make an app that will show information while i click buttons and every button will be active for specific pdf file reading. Any specific help please.
Thanks for help

It is (sadly) not possible to view a PDF that is stored locally in your devices. Android L has introduced the feature. So, to display a PDF , you have two options:
See this answer for using webview
How to open local pdf file in webview in android? (note that this requires an internet connection)
Use a third party pdf Viewer.
You can also send an intent for other apps to handle your pdf.
You can get an InputStream for the file using
getResources().openRawResource(R.raw.ourpdf)
Docs: http://developer.android.com/reference/android/content/res/Resources.html#openRawResource(int)
I am using OSMdroid to display both online and offline data in my app. The offline data are stored in a .zip file with the required structure.
Is it possible to have these offline tiles stored in a directory (extracted .zip file with the same structure)?
Could somebody please tell me how could I achive this?
Thank you.
I am sorry. I should try more before asking. But I am leaving this question here, somebody could find it useful.
Solution:
New MapTileFileProvider. I called it MapTileFileFolderProvider, it is a lightly modified MapTileFileArchiveProvider. It is using folders instead of archives. The modifications are not perfect, it is a "hot solution" that needs someone more experienced in Java/Android to make it properly.
Benefits from loading Tiles from folders:
Faster loading of tiles (I know, I won't recognize the difference).
Easier updates focused only on changed tiles not whole map plans.
Application can download tiles when is in "online mode" and then use the downloaded Tiles offline.
MapTileFileFolderProvider - only modifications
public class MapTileFileArchiveProvider extends MapTileFileStorageProviderBase
public class MapTileFileFolderProvider extends MapTileFileStorageProviderBase {
private final boolean mSpecificFoldersProvided;
private final ArrayList<String> mFolders = new ArrayList<String>();

Well, as far as I understand what you are trying to get... this is more or less what the standard XYTileSource is already doing.
So if you simply use a ready-to-use tile source like this one:
map.setTileSource(TileSourceFactory.MAPNIK);
you will see downloaded tiles files stored in /sdcard/osmdroid/tiles/Mapnik/
The main difference is that it adds a ".tile" extension at the end of each tile file (probably to prevent tools like Android gallery to index all those images).
If you have a ZIP file with tiles ready to use, you could extract them in this directory, and add .tile extension to each tile (355.png => 355.png.tile)
And TileSourceFactory.MAPNIK will be able to use them.
So what I'm trying to do is receive the name of a text file that contains a list of filenames of a sequence of images that I have stored in a separate folder. So I get the path to the actual image files using a scanner and scan through each line of the text file, therefore reading the names of the image files in the context of their actual location. Note that the text file and folder of the images have the same path. My question is how do I get these images into my ArrayList of PImages so I can then later load and display them sequentially in a repeating loop using draw()?
private List <PImage> myImage;
private int myFrameRate, myImageNumber;
private Boolean myRunningStatus;
public AnimationPanel(String path, String textFilename) throws FileNotFoundException {
myImage = new ArrayList <PImage>();
Scanner scanner = new Scanner(new File(path + textFilename));
myFrameRate = 20;
myRunningStatus = true;
myImageNumber = 0;
while(scanner.hasNextLine()){
loadImage(path + scanner.nextLine());
myImageNumber++;
}
scanner.close();
}
public void play() {
myRunningStatus = true;
}
public void pause() {
myRunningStatus = false;
}
public void setup() {
size(300, 200);
frameRate(myFrameRate);
}
public void draw() {
background(255);
if(myRunningStatus == true){
image(myImage.get(myImageNumber), 0, 0);
}
}
I think (untested)
while(scanner.hasNextLine()){
PImage p = loadImage(path + scanner.nextLine());
myImage.add(p);
}
