#28398

Hello,

thank you very much for your answer…
The first part of the answer solved the problem completely.
That’s exactly the command I was looking for..

The second part I explained very poorly. Within the company I work for, we use certain tags to label specific parts, kind of like price tags.
These tags are supposed to be containing consecutive numbers..
Therefore we have to make sure, that each number is only printed once..
If we open the PDF file, even with the printing dialog directly opened, there still is the chance, that the file with for example the numbers 1 through 30, is printed multiple times. We are looking for a way to properly print the PDFs once and only once.
Our current approach would be to create the file and save it on the server (temporarily) and sent it to a printer selected by the user via network. After it was successfully printed, the file will be deleted and the first new number to be used will be saved in a database and used for generating the next set of “tags” with new numbers.

I think that might be the most practical solution, since using the command line in combination with a webserver will get really difficult very quickly…

If you can offer any other idea, we would be more than happy to give it a try…

Thank you for your help!

Kind regards
Niels Göran

We have purchased this product and configured with one of our internal web application which requires single sign on authentication using SiteMinder.

<%@ taglib uri="http://pd4ml.com/tlds/pd4ml/2.6" prefix="pd4ml" %><%@page contentType="text/html; charset=ISO8859_1"%>

This generates a PDF with login screen of my application instead of having content of pd4mlTest.jsp.

Please let us know how to resolve this issue?.

Thanks in advance,

My html file contains images in BMP format encoded as BASE64 (see example.zip).

I downloaded the demo version of PD4ML and run the Converter.class to do a quick test:

java -Xmx512m -cp pd4ml_demo.jar;ss_css2.jar;. Converter example.html example.pdf “” “”

The GIF image has been successfully converted in the PDF file. But the BMP file is missing (see example.pdf).

Does pd4ml support BMP files?

#28724

Does the BMP have transparency mask?
Could you please publish the image in its original form (as BMP file)?
Thank you!

#28725

Please find the file signature.bmp in the attached signature.zip file.

Well, with your sample image we identified and fixed a bug in our code, related to 1-bit bitmap images.

However when I tried your original HTML sample with base64-encoded images, the BMP still failed to appear in the resulting PDF. Which is quite strange.

I have dumped base64-decoded image (“bad image”) and the second image you provided (“good image”). There is a difference in the file headers (the rests of the images are identical). See the attachment.

It is difficult to say if the “bad image” has been corrupted during base64 encoding or it is a species of BMP format, known only to Microsoft.

The impacted bytes are quite important:

Good image:
File type is :BM
Size of file is :4990
Size of bitmapinfoheader is :40
Width is :342
Height is :112
Planes is :1
BitCount is :1
Compression is :0
SizeImage is :4928
X-Pixels per meter is :0
Y-Pixels per meter is :0
Colors used are :2
Colors important are :2

Bad image:
File type is :BM
Size of file is :4990
Size of bitmapinfoheader is :40
Width is :342
Height is :112
Planes is :1
BitCount is :1
Compression is :0
SizeImage is :0
X-Pixels per meter is :2834
Y-Pixels per meter is :2834
Colors used are :2
Colors important are :0

It looks like MS IE repairs the “bad image” on-a-fly and displays it correctly. If you save the image from MS IE you’ll get an image byte-to-byte identical to the “good image”.

We would implement a workaround for such corrupted images, but it is not obvious how to obtain the missing “size of the raw bitmap data” value.

So the print jobs are going to be initiated from the server side (not from client PC)? In the case you’ll anyway need to execute some print command line. I have my doubts if there is an easy way to talk from an application server to a printer (and to render/print a PDF, which is another level of complexity).

As for me a print.bat file with a singe command like
AcroRd32.exe /t %1 “\serverprintername” “Kyocera FS-1010” “192.168.0.1”
is quite a straightforward solution to be executed from the server like that:

[language=java:2hutn6hr]String cmdstart[] = { “cmd.exe”, “/c”, “print.bat”, tempPdfLocation };
Runtime.getRuntime().exec(cmdstart);[/language:2hutn6hr]
Of course, printer names/locations could be passed to the script as a parameter as well.

#28719

Yes, it looks like a bug in the converter.
I’ve just opened a ticket to be resolved with the next beta release.

Hello,
I keep getting NPEs when I’m attempting to render an RTF doc.

Below is the test.

Thanks,

#28733

Thank you for the report!

We’ve just fixed the issue in the development build. The fix will be available with the next beta release.

#28721

> “/userdata/includes/arialScreenReg.css”
Is in the path /userdata is a web application name or just a legacy path, which currently makes no special sense?

#28722

Yes…its just a path. But as I tried to explain in my post, it really should be:

without the starting ‘slash’. But as our current software handles this just fine, it was only an issue when I started to look for a replacement. Another product allows a use of an XSL tranformer to be applied before the conversion of HTML to PDF and I was wondering if PD4ML had something similar. If not, I figure I have 2 choices…either do the XSL transformer before calling PD4ML or have the client manually update their hundreds of HTML files. Just wanted to make sure I did not miss any functionality of PD4ML. Thanks.

#28723

For web scenarios PD4ML JSP taglib offers a tag to pre-process such type of paths, however it makes nothing special: it looks for a given pattern (for example, “”/userdata/includes”) and substitutes it with a desired string (“”userdata/includes”) . It works with the source HTML document as with a single string, ignoring the document structure – you could always implement your own similar solution.

But I would recommend you to create a simple custom resource loader:
post43.html
and to interpret the “non-standard” paths the way you like.

#28720

Just tested with the development build 3.80 – the issue has been already solved. However the version still did not pass all QA tests. It should not take longer than one week.

#26637

I am trying to make anchor tags () look like normal text in the pdf by changing the text color to match the text on the rest of the page, and by removing the underlines.

I am trying to do this by adding a style like this:

a {
color: #000000;
text-decoration: none;
}

The color of the links is changing…but the underlines do not disappear. If I change the value of the text-decoration to ‘line-through’, I get both the underline and the strike through…so I know text-decoration is supported.

The documentation states that a value of ‘none’ is supported by text-decoration.

I am using the Java pro version 380

Thanks for any help.
