Nope. It used to work before I added the footer code you have provided me. Thank you.

#28415

If I remove the footer code which is above the render page, the link is working as is. It is not giving me any error details.

All the code currently I am using in my application is posted in one of my previous posts.

Thank you

Hello pd4ml-team,

I just would like to know, what the status is on the initialPageNumber parameter.
We are about to deploy the solution for our customer, so it would be really great to have this feature already in place for the customer (We will buy the license soon).

Thank you for your help!

Kind regards
Niels Göran Blume

Steve, we implemented the first version of the feature. It is not available for download yet, so please contact support pd4ml com

Now PD4ML checks if there is PD4CanvasHandler class available in the classpath and invokes its getImage() method for each tag occurrence.

Below is a dummy implementation of the handler class.

[language=java:hg0efl8i]import java.awt.Color;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.ByteArrayOutputStream;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Vector;

import javax.imageio.IIOImage;
import javax.imageio.ImageIO;
import javax.imageio.ImageWriteParam;
import javax.imageio.ImageWriter;
import javax.imageio.stream.MemoryCacheImageOutputStream;

import org.zefer.cache.DynamicImageHandler;

public class PD4CanvasHandler extends DynamicImageHandler
{
public byte[] getImage(String tagName, int width, int height, String id, HashMap attributes, String onBodyLoad, Vector scriptSections) throws Exception {

System.out.println(“canvas ID: ” + id);
System.out.println(“onBodyLoad: ” + onBodyLoad);
System.out.println(“attributes: ” + attributes);

if (scriptSections != null) {
Iterator ii = scriptSections.iterator();
while (ii.hasNext()) {
String js = (String)ii.next();
System.out.println(”

---

“);
System.out.println( js );
}
}
System.out.println(”

---

“);

BufferedImage bi = new BufferedImage(width, height, BufferedImage.TYPE_BYTE_INDEXED);
Graphics g = bi.getGraphics();

g.setColor( Color.white );
g.fillRect(0, 0, width, height);
g.setColor( Color.red );
g.drawString(“Canvas handler test”, 30, 30);
g.dispose();

Iterator iter = ImageIO.getImageWritersByFormatName(“png”);
ImageWriter writer = (ImageWriter)iter.next();
ImageWriteParam iwp = writer.getDefaultWriteParam();

ByteArrayOutputStream baos = new ByteArrayOutputStream();
MemoryCacheImageOutputStream output = new MemoryCacheImageOutputStream(baos);
writer.setOutput(output);
IIOImage image = new IIOImage(bi, null, null);
writer.write(null, image, iwp);
writer.dispose();

return baos.toByteArray();
}
}[/language:hg0efl8i]

If your idea with RhinoCanvas works, we’ll add a new method to make possible a canvas output in vector form.

For the time being PD4ML parser is not able to read tags. It needs explicit opening and closing tags: and

#28429

It is difficult to say without an HTML sample.

A typical reason – trailing white spaces at the end of the document. Try to add

BODY { border: 1 solid red }

CSS style to visualize the actual document content edges. Also make sure there is no explicit page break directives.

#28416

There is a new PD4ML.NET version available for download. Please check if it solves the issue.

#26521

I have many HTML documents constructed like below:
<div ><br /> <div>div text</div><br /> <table><br /> <tr><br /> <td class="a">cell text</td><td class="a">cell text</td><br /> </tr><br /> ...<br /> </table>
and associated CSS
body{<br /> font-size:70%;<br /> }<br /> table {<br /> font-size:100%;<br /> }<br /> td.a {<br /> font-size:100%;<br /> }

In HTML view (IE, FF …) both: “div text” and “cell text” have the same font-size (70%) but in generated PDF the “cell text” is bigger than the “div text”.
Is it a bug in PD4ML or is it a feature ?
Is the way to achieve in PDF the same result as in HTML without CSS manipulation ?

It depends on the server side session mechanism of you web application. You need to propagate the session ID correctly with the URL passed to PD4ML.

For the regular J2EE application a solution is to add the jsessionid parameter to URLs:

http://your.server.net/webapp/sourcepage.jsp;jsessionid=8764587625?param1=value1&param2=value2

How will this work with .Net MVC. need it to render an MVC action that is based on an authentication requirement.

#26522

Hi together,

I try to place a footnote text at the bottom margin of a page.
For this reason I use the footnote tag from the taglib. While it exists at the correct place in HTML, in Pdf it will be displayed two page earlier.
If I try to implement it using a div tag positioned absolutely top/leftI get it right for one element constellation. But if the element structure changes the footnote will be anywhere maybe nowhere.
If I place it absolutely bottom positioned the HTML will be right, but the footnote will be elsewhere but not at the desired place.
What´s wrong? What can I do?
Thanks
Lutz

As a rule a session ID is propagated via cookies or as an URL parameter. Just check how it is in your case and invoke pd4ml.setCookie() before render() call or add the session ID to the URL string:

http://myserver.com/(tsdfg2usdfgvrj3vxgvg)/start.aspx

(the actual sessionID-enabled URL syntax may vary)

#28431

An HTML sample and its resulting PDF would help a lot to analyze the issue. Please publish them here or send to support pd4ml com

#28393

The feature is still under development – there are some technical complexities with the implementation. In a couple of days we’ll inform you if it is going to be included to the forthcoming release.

#26523

hello,

how can i set the default zoom factor e.g. 100% for the pdf file? I use the command line tool to create the pdf.

greetings

#28432

As far as I know there is no way to pre-define in PDF initial zoom factor. You may define it as AcroRead command line/URL parameter.

See http://partners.adobe.com/public/developer/en/acrobat/PDFOpenParameters.pdf

In PDF file itself you may define starting document view mode. For example the code

[language=java:3sx4er5j]Map m = new HashMap();
m.put(PD4Constants.PD4ML_DOCUMENT_VIEW_MODE, “SinglePage”);
pd4ml.setDynamicParams(m);[/language:3sx4er5j]

(or
Pd4Cmd … -param pd4ml.document.view.mode SinglePage )

forces AcroRead to open the doc scaled down to fit viewer window.
