Changes in the PD4ML license price list
 
 

We would like to inform you that we have changed the prices of some of our products. This decision has been a long time coming and has been made due to the need to adapt to changing market conditions and to the increase in development costs in the EU.

We understand that this may come as an unexpected to some who are currently evaluating or planning to renew their license service. Please contact us within the next month to inquire about possible discounts.

We appreciate your support and strive to maintain the quality of our products and services.

Creating DOCX Files
 
 

v4.0.19 introduces support for creating OOXML (DOCX) files from HTML.

It is already functionally superior to the long-standing PD4ML HTML to RTF converter. It allows you to define text and paragraph styles, nested tables, ordered and unordered lists, headers and footers, table of contents, hyperlinks, bookmarks, borders, backgrounds, and embed images.

To force DOCX output you only need to trigger pd4ml.writeDOCX() API method instead of pd4ml.writePDF() in usual conversion scenarios.

The converter is available under the PD4ML DMS or PD4ML UA license.

PD4ML Fonts Tool
 
 

To simplify the creation of font mapping files, PD4ML v4.0.16 introduces a handy tool. The tool is implemented as an utility of the interactive PD4ML Converter

How to use it

Run the converter, as described by the link /support-topics/pd4ml-v4-programmers-manual/ and click the [Fonts Tool] button on the status bar of the application window.

It will prompt you for the location of the font directory. Select a directory. We can start with system fonts like C:\Windows\Fonts

Because the system font directory contains an excessive number of fonts that your application doesn’t really need, you can filter them out by entering a comma-separated list of font name patterns in the input field next to the “Filter by Font File Name” button. Apply the filter by pressing the button. The resulting list will include only those fonts whose filenames case-insensitively match the given patterns.

The generated list is editable, so you can manually refine it.

At this point you have four options:

  • Close – is obvious: close the tool and lose the current font mapping configuration
  • Use – use the font configuration only in the current session of the PD4ML Converter, without saving it.
  • Save Mapping File – creates a pd4fonts.properties file that can later be referenced from your application with pd4ml.useTTF() API call. If the chosen mapping file location is different from the original font directory (which is a good idea if you are using the system font directory), pd4fonts.properties will include a link to the font dir, allowing PD4ML to find the actual font files.
  • Save as JAR – packages the listed fonts and the corresponding pd4fonts.properties into a JAR file. Fonts are stored in the “pdffonts” JAR subdirectory by default, so once the JAR is deployed with a PD4ML-enabled application, the font configuration can be referenced with pd4ml.useTTF("java:pdffonts") API call. The subdirectory name can be customized by uncommenting and setting the jar.folder=pdffonts property.

Apache Batik SVG plugin control
 
 

PD4ML implements its own basic SVG renderer, and also allows you to use third-party libraries for the task. If it finds Apache Batik SVG Toolkit among the available libraries, it will automatically switch to it.

Batik tries to implement most of the features of SVG. But, unfortunately, it is very sensitive to even minor file format errors, and there is no way to change its error policy: it always throws exceptions, and there is no switch to turn them into warnings, for example.

In such cases, the best workaround would be to disable Batik and let the built-in SVG engine do the rendering.

Java code to disable Batik:

com.pd4ml.plugins.BatikSvgCustomTag.disable = true;

Disable in pd4browser.properties:

svg.batik=false

CSS Flexible Box Layout support added
 
 

PD4ML v4.0.6 introduces flexbox layout support.

Children of a flex container can “flex” their sizes, either growing to fill unused space or shrinking to avoid overflowing the parent. Both horizontal and vertical alignment of the children is supported.

Automatic Font Kerning Support
 
 

PD4ML v4.0.4 introduces optional font kerning support. Kerning is an addition or reduction of space between two characters (glyphs) of a proportional font. As a rule a rendered text is visually much more pleasing when the kerning is applied.

PD4ML uses kerning pairs info from TTF/OTF fonts (if available). For the standard built-in Type1 fonts the kerning info is known and included to PD4ML product itself.

The feature is also implemented in our older development branch v3.11.0 due to its importance

RTF Output Performance
 
 

The recent PD4ML builds (both v3 and v4) refactor RTF output logic to improve conversion performance by bulky input HTML documents.

Now, even in extreme situations, the performance is comparable with PDF output and very often outperforms it.

 

 

 

 

 

 

 

 

CSS Transform Property Supported
 
 

PD4ML v4.0.3 implements CSS transform feature e.g. to rotate, scale, skew HTML objects.

Here is a list of supported transform functions:

  • translate(x, y)
  • translatex(x)
  • translatey(y)
  • skew(x-angle,y-angle)
  • skewx(x-angle)
  • skewy(y-angle)
  • scale(x,y)
  • scalex(x)
  • scaley(y)
  • matrix(n,n,n,n,n,n)
  • rotate(angle)
  • rotatez(angle)
