#26962

Dear support,
We have faced with the following problem:

Precondition. Our system provides printing capabilities for label printers. Label page size, margins (aka insets), font-size and font (aka font-family) are all the params which are set dynamically. Font-size is set on html level.

Problem. Specified font-size is not kept at all and we created a formula, which generates appropriate userWidth( setHtmlWidth ) to maintain specified font-size.
public static final long getCalucaltedHtmlWidth (int leftMarginMM, int rightMarginMM, int pageWidth, int fontSize){<br /> double weight = 13.7;<br /> double fontSizeKoef = (1 - fontSize*1.0/8 )* weight +16;<br /> return Math.round(fontSizeKoef*(pageWidth - leftMarginMM - rightMarginMM)/PD4Constants.TRANSLATE_FACTOR);<br /> }

All the constants were defined experimentally. We tried protectPhysicalUnitDimensions() method to let pd4ml do stuff for us, but for some reasons it had no impact on maintaining predefined font-size.

Please advice if there is any better approach than temporary solution chosen at the moment,

thanks,

Is there a way to embed an entire font in the PDF rather than just a subset? We are evaluating the software, and are likely going to purchase for an adding an upcoming feature to our product. This is one of the requirements.

I currently am able to embed the font, but I can only get it to embed a subset. We have our fonts installed in a system directory and are using PD4ML through the java API:

<br /> // FontUtil is our own internal class<br /> pd4ml.useTTF(FontUtil.getFontsDirectory().getAbsolutePath(), true);<br />

The resulting PDF seems to just have subsets. If I open in Adobe reader and click File > Properties > Fonts, I see something like: CourierNewPSMT_PDF_Subset (Embedded)

Is there anything I can do through the java API to embed the entire font?

I try to merge 2 PDF files
This works fine almost every time
But now we have some problems with PDF files

Our code is as below

public static boolean merge (String inFile1, String inFile2, String outFile){
boolean success=false;
try {
InputStream inputstream1 = new FileInputStream(inFile1);
InputStream inputstream2 = new FileInputStream(inFile2);
OutputStream output = new FileOutputStream(outFile);

org.zefer.pd4ml.PD4Document.mergePDFs(inputstream1, inputstream2, output);
success=true;
}
catch(Exception e){
System.out.println(e.getMessage());
}

return success;

}

The error message that we get is this
org.zefer.pd4ml.npdf.parser.obj.h incompatible with org.zefer.pd4ml.npdf.parser.obj.d

Do we use this method in wrong way?
Why does some PDF files work and other don’t?

Hi,
we have implemented our custom ResourceProvider

In case, we are including large resources, it will be better to provide resources as InputStream instead of byte array (to use less memory). Furthermore for resources such as file hosted on the file system, it is not efficient to load them as byte array instead of directly including them into the resulting PDF.

What do you think of providing a new ResourceProvider that allow custom classes to override :

InputStream getResourceAsStream(String resource, boolean debugOn)

instead of:

byte[] getResourceAsBytes(String resource, boolean debugOn)

Thanks

Hi,
rendering this content :

generates an error message on the console:

Bad Base64 input character 0x2e at 0 ([.])

Tested with version: PD4ML 398fx3 Pro

Thanks

Try to use an empty tag or remove the dot from

We’ll update the tag implementation to ignore tag content when dynvalue attribute is set.

#29843

We plan to optimize resource loading / caching in totally refactored v4.x

Your proposal would make sense only by attachment embedding. Other type of loaded resources do not win a lot:

CSS – should be instantly loaded and parsed anyway

images – PD4ML does not trust a file extension. It always loads an image and scans its bytes to determine image file type and dimensions. If explicitly configured, after that it unloads the image to a temp directory to free up RAM.

Despite the impression, that it allocates a lot of memory because of images and other resources, it is not always true. A specifics of HTML rendering is that it should allocate a number of Java objects even for a single standalone whitespace. So parsed HTML (with layouting info) is the main “RAM eater”.

#29842

We’ve just fixed the issue in the development build.

The reason is that in the problematic PDF an image size is unexpectedly given not as an integer, but as a reference to another object (which holds only an integer). Now the case is correctly worked around.

Hi,

We are using PD4ML 3.9.2 library for converting HTML documents to PDF. We have a requirement to validate the CSS Styles in HTML document before converting the same to PDF.

We have been using the CSSSOMParser (from cssparser 0.9.17 jar) earlier to validate the CSS present in the HTML content.

But since PD4ML uses ss_css2 3.9.2 , we ended up replacing the existing CSS jar i.e cssparser 0.9.17 with the ss_css2 3.9.2 due to jar conflicts.

The CSSSomParser in cssparser 0.9.17 provides a ErrorHandler that can be used to validate the CSS which is not available with CSSSomParser in ss_css2 3.9.2 library.

Could you please let me know if there are any plans of upgrading ss_css2 to use the latest cssparser jar OR are there any workaround that we can achieve validation of CSS styles in HTML using PD4ML 3.9.2

-Thanks

Hey guys. This is my first post. Hope you guys can help me out.

I have a page that I need in landscape. My default ‘orientation’ is set to ‘portrait’.

I am trying to rotate my page with this line:
<pd4ml:page.break pageFormat="rotate" />
It works if there is HTML code before the line. If it’s the first line in my HTML body it doesn’t work. I.e. I add and empty tag and add the line after that. I will then get an empty page and then the landscape page I was aiming for.

When I set my default page ‘orientation’ to ‘landscape’ it doesn’t have the same effect as rotate. It does return a page in ‘landscape’, but now the HTML table on this page overflows on the right hand side and doesn’t fit perfectly like when I use ‘rotate’.

Thanks

I am new to pd4ml and trying evaluation version, I try to use pd4ml java library

Code Snippet:

pd4ml.useTTF(“java:fonts”, true);
pd4ml.enableDebugInfo();
pd4ml.setHtmlWidth(1000);
java.io.FileOutputStream fos = new java.io.FileOutputStream(“c:/test123.pdf”);
pd4ml.render(“http://stage01:8080/”,fos);

in the debug info i am getting

Help me in finding the cause of the css parsing issue.

Hello ,

I created the pd4fonts.properties with the command as below

java -jar pd4ml.jar -configure.fonts /path/to/my/fonts/

I used following code on Java Side

pd4ml.useTTF(“C:EpicFontspd4fonts.properties”, true);

Alternatively I downloaded allfont.zip file and added fonts.jar to deployment and tested and that too didn’t work.

Please advice on what can be the problem.
