  - useTTF
```
public void useTTF(java.lang.String pathToFontDirs)
            throws java.io.FileNotFoundException
```
    enables TTF font embedding subsystem. Available only in professional version of PD4ML.
    Parameters:
    
    pathToFontDirs - URL of a font directory or a path to pd4fonts.properties mapping file
    The font directory should contain pd4fonts.properties mapping file. The file records have the following format:
    font_name=file_name
    
    font_name - font name used in the source HTML.
    file_name - font file name (should exist in the font directory)
    
    Example:
    Book\ Antiqua=BKANT.TTF
    To generate the file automatically you may use the command line call:
    java -jar pd4ml.jar -configure.fonts <fontdir>
    After the generation, please edit the file and remove manually all references to the fonts, that are not allowed to be redistributed. Contact your TTF fonts provider for the info.
    In order to support J2EE deployments a PD4ML-specific protocol "java:" is supported to load font resources via ClassLoader.
    Example: useTTF("java:myfonts");
    In that case the runtime looks for a fonts folder named "/myfonts" in all JAR files available for the application class loaders. The content of the folder should correspond to the rules described above: pd4fonts.properties + *.ttf
    Example: useTTF("java:");
    The simplest case. The runtime looks for a JAR file which contains pd4fonts.properties + *.ttf in the root directory.
    
    Throws:
    
    java.io.FileNotFoundException - if pd4fonts.properties file is not found or the file refers to missing font files
  - useTTF
```
public void useTTF(java.lang.String pathToFontDirs,
                   boolean generateFontMappingFileIfMissing)
            throws java.io.FileNotFoundException
```
    Parameters:
    
    pathToFontDirs - URI of TTF file directory
    
    generateFontMappingFileIfMissing - forces to index available fonts (if they are not indexed yet). The indexing may be time/resource consuming. If true, make sure PD4ML has write permission to pathToFontDirs
    
    Throws:
    
    java.io.FileNotFoundException - font directory not found
    
    See Also:

                                  boolean imageGeneration)
```
    Returns page margins object for a specified page number. The result depends on default page margins, page margins specified with setPageMargins() calls as well as page formats defined in-line in CSS (page at-rule).
    
    Parameters:
    
    pageNum - One-based indexed page number (the leading page is #1)

  - setHtmlWidth
```
public void setHtmlWidth(int width)
                  throws InvokeException
```
    defines desired HTML page width in screen pixels. Virtually it can be seen as a web browser window horizontal resize.
    In the resulting PDF the HTML width is mapped to the paper page width (minus insets). There is no way to specify HTML page height. The height in screen pixels is set automatically depending on the width and the paper page proportions.
    
    Parameters:
    
    width - HTML width in screen pixels
    
    Throws:
    
    InvokeException - when the width is not a positive value great that 0.
  - adjustHtmlWidth
```
public void adjustHtmlWidth(boolean adjust)
```
    sets htmlWidth to the most right margin of the HTML block content. Calling the method would force PD4ML to build HTML layout with htmlWidth set by setHtmlWidth(int), to determine the most right edge of rendered content and to use the value for PDF mapping. Notes:
    
    The method takes no effect for multi-URL PD4ML call: render(URL[],OutputStream)
    In order to use the method efficiently, it is important to call setHtmlWidth(int) with a parameter value, which is greater than the expected right edge offset.
    If the source document has HTML objects, whose width is set to 100%, than the method call is meaningless.
    As long as htmlWidth affects HTML-to-PDF scale factor, usage of the method causes inconstancy of font/object sizes in the resulting PDF from document to document.
    Parameters:
    
    adjust - enables the adjustments
    
    Since:
    
    3.0.2

```
    Parameters:
    
    pdfFormat - Forces PD4ML to output either a regular PDF or a PDF format compliant with PDF/A specification. PDF/A specification requires all used fonts to be embedded to the resulting document.

  - protectPhysicalUnitDimensions
```
public void protectPhysicalUnitDimensions(boolean keepPhysicalUnitDimensions)
```
    makes PD4ML to output PDF objects respecting dimensions/font sizes given in "in", "pt", "cm" etc. Use the method carefully: as long as it triggered, there is no single HTML-to-PDF scale factor for all HTML objects. The resulting PDF layout may appear visually corrupted. If the method is not triggered, all sizes given in physical measurement units are converted to their screen pixel equivalents (using 72dpi) before HTML layout. The method call can not be combined with adjustHtmlWidth() and fitPageVertically() calls, which affect HTML-to-PDF scale factor their own way.
    
    Parameters:
    
    keepPhysicalUnitDimensions - enable if true
    
    Since:
    
    v3.0.4, v4.0.9

    The method defines custom properties for PDF document meta data. The method takes effect only with PD4ML DMS and PD4ML UA license types.
    
    Parameters:
    
    key - a unique name, which must not be one of the standard property names Title, Author, Subject, Keywords, Creator, Producer, CreationDate, ModDate and Trapped
    
    value - data itself
    
    hide - makes the metadata not appear in the PDF document properties dialog of Acroread
  - applyKerning
```
public void applyKerning(boolean enable)
```
    Forces PD4ML to align font glyphs to each other according to the font kerning hints (if available). The API call takes effect only by PDF generation.
    
    Parameters:
    
    enable - - enables the feature
  - enableLigatures
```
public void enableLigatures(boolean enable)
```
    Forces PD4ML to load TTF/OTF glyph susbstitution tables, to apply ligature replacements and to build compound glyphs. The feature requires pd4ml_fonttool.jar
    
    Parameters:
    
    enable - - enables the feature
  - getCache
```
public java.lang.Object getCache()
```
    Returns:
    
    cache object to be reused by new PD4ML instances. The cache object is not reentrant, so a single instance cannot be used from multiple threads.
    
    See Also:
    
    setCache(Object)
  - setCache
```
public void setCache(java.lang.Object fontCache)
```
    Parameters:
    
    fontCache - cache object returned by other PD4ML instance
    
    See Also:
    
    getCache()
  - asyncResourceLoader
```
public void asyncResourceLoader(int threadPoolSize)
```
    enables asynchronous resource loading (graphics, attachments etc) if thread pool size is not equal 0. By default the asynchronous loader is disabled. As the loader spawns new threads, usage of it is discouraged in Java EE environment.
    
    Parameters:
    
    threadPoolSize - loader thread pool size. If the value is negative, it it does not limit the pool size: creates new threads as needed, but will reuse previously constructed threads when they are available.
