I'm using ItextPdf 5.
I have an SVG file with specifical font (integrated in svg).
When I print my SVG (using batik 1.8) the graphic is print on my document, but fonts are blocked, so, can't select them.
see below my java code :
public class ItextPdfSmallTests {
#Test
public void svgFontsTest() throws IOException, DocumentException, URISyntaxException {
String RESULT = "C:\\test\\svgFontsTest.pdf";
Document document = new Document(PageSize.A4, 36, 36, 54, 36);
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(RESULT));
document.open();
document.add(new Paragraph("SVG Example"));
int width = 250;
int height = 250;
PdfContentByte cb = writer.getDirectContent();
PdfTemplate template = cb.createTemplate(width, height);
PdfPrinterGraphics2D g2 = new PdfPrinterGraphics2D(cb, width, height, new MyFontMapper(), PrinterJob.getPrinterJob());
PrintTranscoder prm = new PrintTranscoder();
URI svgFileURI = getClass().getResource("myfont.svg").toURI();
TranscoderInput ti = new TranscoderInput(svgFileURI.toString());
prm.transcode(ti, null);
PageFormat pg = new PageFormat();
Paper pp = new Paper();
pp.setSize(width, height);
pp.setImageableArea(0, 0, width, height);
pg.setPaper(pp);
prm.print(g2, pg, 0);
g2.dispose();
ImgTemplate img = new ImgTemplate(template);
document.add(img);
document.close();
}
class MyFontMapper extends DefaultFontMapper {
#Override
public BaseFont awtToPdf(java.awt.Font font) {
try {
return BaseFont.createFont("AmaticSC-Regular.ttf", BaseFont.WINANSI, false);
} catch (DocumentException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
}
}
is it possible make it editable ?
thanks for your helps

iTextSharp-generated PDFs now cause Save dialog in Adobe Reader X
(2 answers)
Closed 5 years ago.
I am generating some reports with iTextSharp 5.
Opening the generated .PDF-file, everything looks and actually is fine with most PDF-readers.
When I open the PDF using AdobeReader(DC) however, it asks me if i want to save the changes on close. Although I didn't change anything.
Hitting 'Cancel' sure makes the message window go away, but hitting save causes the file to actually shrinks in size.
Now what is happening there? And why? How can I disable it?
The users of the application are most likely gonna use AdobeReader as well.
I don't want them to see the save dialog anytime they open a report.
Here is my BaseReport class

I'm working towards properly integrating the stanford segmenter within SOLR for chinese tokenization.
This plugin involves loading other jar files and model files. I've got it working in a crude manner by hardcoding the complete path for the files.
I'm looking for methods to create the plugin where the paths need not be hardcoded and also to have the plugin in conformance with the SOLR plugin architecture. Please let me know if there are any recommended sites or tutorials for this.
I've added my code below :

Please advise me How do I convert text files to .arff format(weka)
because i wan to do data clustering for 1000 txt file.
regards
There are some converters implemented in WEKA, just find the right format or make little changes to your data (using awk, sed...).
Here is the API pages related to this topic: http://weka.sourceforge.net/doc.stable/weka/core/converters/package-summary.html
For exapmle here is how to convert from CSV to ARFF:
java weka.core.converters.CSVLoader filename.csv > filename.arff
Here is the code you can use
package text.Classification;
import java.io.*;
import weka.core.*;
public class TextDirectoryToArff {
public Instances createDataset(String directoryPath) throws Exception {
FastVector atts;
FastVector attVals;
atts = new FastVector();
atts.addElement(new Attribute("contents", (FastVector) null));
String[] s = { "class1", "class2", "class3" };
attVals = new FastVector();
for (String p : s)
attVals.addElement(p);
atts.addElement(new Attribute("class", attVals));
Instances data = new Instances("MyRelation", atts, 0);
System.out.println(data);
InputStreamReader is = null;
File dir = new File(directoryPath);
String[] files = dir.list();
for (int i = 0; i < files.length; i++) {
if (files[i].endsWith(".txt")) {
double[] newInst = new double[2];
File txt = new File(directoryPath + File.separator + files[i]);
is = new InputStreamReader(new FileInputStream(txt));
StringBuffer txtStr = new StringBuffer();
int c;
while ((c = is.read()) != -1) {
txtStr.append((char) c);
}
newInst[0] = data.attribute(0).addStringValue(txtStr.toString());
int j=i%(s.length-1);
newInst[1] = attVals.indexOf(s[j]);
data.add(new Instance(1.0, newInst));
}
}
return data;
}
public static void main(String[] args) {
TextDirectoryToArff tdta = new TextDirectoryToArff();
try {
Instances dataset = tdta.createDataset("/home/asadul/Desktop/Downloads/text_example/class5");
PrintWriter fileWriter = new PrintWriter("/home/asadul/Desktop/Downloads/text_example/abc.arff", "UTF-8");
fileWriter.println(dataset);
fileWriter.close();
} catch (Exception e) {

}
}
}
