- Method Detail
  - applyLicense
```
public boolean applyLicense(String license)
```
    applies license code. The method should be called before initiation of PDF, RTF or image output. The method is implicitly called by PD4ML(String) If the method is not invoked, the software runs in demo mode: its output is watermarked and supplied with an ad footer. An applying of evalution license removes the watermarks but the footer message remains. An applying of a commercial license removes both watermark and footer in permitted output modes.
    
    Parameters:
    
    license - license string or license file URI
    
    Returns:
    
    true if the license is valid

  - useTTF
```
public void useTTF(String pathToFontDirs)
            throws 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:
    
    FileNotFoundException - if pd4fonts.properties file is not found or the file refers to missing font files
  - useTTF
```
public void useTTF(String pathToFontDirs,
                   boolean generateFontMappingFileIfMissing)
            throws 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:
    
    FileNotFoundException - font directory not found
    
    See Also:
    
    useTTF(String)

```
    Returns page dimensions object for a specified page number. The result depends on default page format, page formats specified with setPageSize() calls as well as page formats defined in-line in CSS (page at-rule) or in HTML (<pd4ml:page.break> tag attribute).

                                  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
