> Is it possible to convert PDF to PDF UA (accessible PDF) using PD4ML

No. I am afraid this type of conversion is not possible robust automated way.

PDF/UA requires a lot of additional information, normally missing in regular PDFs: alternative text description for all content portions, for visual elements and artifacts; requires structure information (tagging) for tables, lists, headings etc.
By HTML-to-PDF conversion the info can be provided via HTML tag attributes, the structure info comes from the HTML document structure.

We have purchased the PD4ML V4 Java Single PRO License and plan to use it within the Eclipse environment on Java Module Projects. However, we are facing issues with activating the license. We are using the org.zefer.pd4ml.PD4ML class with the pd4ml-4.0.19fx1-jakarta.jar file. We chose not to use com.pd4ml.PD4ML as its structure is very different from that in org.zefer.pd4ml.PD4ML.

Below is the code we use for PDF conversion, but we are still receiving a demo license warning. Despite meticulously following the instructions provided by the system, we have not been able to find a solution.

Sample Code:
org.zefer.pd4ml.PD4ML pd4ml = new org.zefer.pd4ml.PD4ML();
pd4ml.setPageInsets(new Insets(15, 5, 10, 5));
pd4ml.setHtmlWidth(1024);
pd4ml.setPageSize(pd4ml.changePageOrientation(format));
..

Hi! Try to switch debug on with pd4ml.enableDebugInfo() API call and inspect STDOUT for possible license reading errors.

pd4ml.lic is expected to be in the application workdir or in the classpath root (not in lib/ dir where pd4ml.jar is)

Also even if you use legacy API with PD4ML v3 wrapper, you always have access to v4 instance with

pd4ml.pd4mlNew.applyLicense(code);

Hi PD4ML team,

We are using an older version of pd4ml which is using JSP tags to convert HTML to PDF. Now we are planning to use the latest version of it but looks like the new tag library is not working.

Do we have a working example of the latest version? We are trying 4.0.19fx1-jakarta version.

Can you please help?

Thanks
Satender

Hi,
We are using the PD4ML Trasform tag in the jso to convert the page to PDF. The tag is causing the page to be reloaded in Safari browser. Basically the page is getting loaded twice.
Please let me know if anyone has encountered this and if there is a fix.
Note: It worked fine for me on Chrome but another user reported the reload on Chrome.
Here is the tag that we are using:

<%@ taglib uri=”http://pd4ml.com/tlds/4.0&#8243; prefix=”pd4tl” %><%@page
contentType=”text/html; charset=UTF-8″%><pd4tl:transform
screenWidth=”900″
pageFormat=”A4″
pageOrientation=”portrait”
pageInsets=”25,25,25,25,points”
fileName=”filename123.pdf”
inline=”true”
enable=”true”
debug=”1″>

Thanks in advance.

Deciding which license key to use prompts considerations of compatibility, validity, and entitlements. It’s essential to choose the appropriate key that aligns with the product version and user requirements for seamless operation.

The left-border in the table is cut-out by the parent div, but it should not since div and parent-div have same width.

PD4ML v3 renders it correctly, but PD4ML v4 does not (it cuts out the border).

The code follows. For the files, see attachments:
– issue-1.html is the HTML source to be converted into PDF
– issue-1-PDF4MLv3.pdf is the correct rendering made by version 3
– issue-1-PDF4MLv4.pdf is the wrong rendering made by version 4

    public static void main(String[] args) throws Exception {
        PD4ML pd4ml = new PD4ML();
        pd4ml.applyLicense("...omissis...");
        
        pd4ml.setPageSize(new PageSize(595, 842));
        pd4ml.setPageMargins(new PageMargins(0, 0, 0, 0));
        pd4ml.setHtmlWidth(1190);
        pd4ml.generateForms(true, "sans-serif");


        String html = Files.readString(Paths.get("src/main/resources/sblend5.html"));
        ByteArrayInputStream bais = new ByteArrayInputStream(html.getBytes("UTF-8"));
        pd4ml.readHTML(bais, null, "utf-8");

        File pdf = File.createTempFile("result", ".pdf");
        FileOutputStream fos = new FileOutputStream(pdf);
        pd4ml.writePDF(fos);

        
        Desktop.getDesktop().open(pdf);
    }

We use Java 21 and Tomcat 9.
There are two “versions” of the same “version”, one Jakarta and one not-Jakarta.

Which are the differences?

We use PD4MLv3 and there are:
– pd4ml.prof.3115fx3.zip
– pd4ml.prof.3115fx4-jakarta.zip

Which one is the correct one?

#38261

The difference between the versions is in use of jakarta.servlet.* instead of javax.servlet.*. Both are built with Tomcat 9.0’s servlet-api.jar and jsp-api.jar

If your environment is strict javax-less, use the jakarta version. If not, then the regular one since currently it is a bit advanced at the patch level.

Hello,

I’ld like to know where exactly I can find documentation about all JSP custom tags (i.e. pd4ml:page.header etc.) and all their attributes, etc.

On the programmers manual there are no details about.

many thanks
