## 9.6. Extract Font Information to XML

As described in chapter 3.12: “Fonts” fonts are a topic which need to be tested. Information about fonts can be extracted using the utility `ExtractFontInfo`. This generated file shows you, how PDFUnit sees the fonts.

The algorithm that generates the XML file is the same as the one used by the PDFUnit tests.

### Program Start

    ::
    :: Extract information about fonts of a PDF document into an XML file
    ::

    @echo off
    setlocal
    set CLASSPATH=./lib/aspectj-1.8.7/*;%CLASSPATH%
    set CLASSPATH=./lib/bouncycastle-jdk15on-153/*;%CLASSPATH%
    set CLASSPATH=./lib/commons-collections4-4.1/*;%CLASSPATH%
    set CLASSPATH=./lib/commons-logging-1.2/*;%CLASSPATH%
    set CLASSPATH=./lib/pdfbox-2.0.0/*;%CLASSPATH%
    set CLASSPATH=./lib/pdfunit-2016.05/*;%CLASSPATH%

    set TOOL=com.pdfunit.tools.ExtractFontInfo
    set OUT_DIR=./tmp
    set IN_FILE=fonts_11_japanese.pdf
    set PASSWD=

    java  %TOOL%  %IN_FILE%  %OUT_DIR%  %PASSWD%
    endlocal

### Input

For the Japanese PDF document `fonts_11_japanese.pdf` the Adobe Reader® shows the following fonts:

### Output

The output file `_fontinfo_fonts_11_japanese.out.xml` contains the underlined names:

    <?xml version="1.0" encoding="UTF-8" ?>
    <fonts>
      <font basename="Arial-BoldMT"       name="Arial-BoldMT"
            type="TrueType"               vertical="false"          embedded="false" />
      <font basename="ArialMT"            name="ArialMT"
            type="TrueType"               vertical="false"          embedded="false" />
      <font basename="Century"            name="MEEADE+Century"
            type="TrueType"               vertical="false"          embedded="true"  />
      <font basename="HGPGothicE"         name="MFHLHH+HGPGothicE"
            type="Type0"                  vertical="false"          embedded="true"  />
      <font basename="MS-Gothic"          name="MDOLLI+MS-Gothic"
            type="Type0"                  vertical="true"           embedded="true"  />
      <font basename="MS-Gothic"          name="MDOLLI+MS-Gothic"
            type="Type0"                  vertical="false"          embedded="true"  />
      <font basename="MS-Mincho"          name="MEOFCM+MS-Mincho"
            type="Type0"                  vertical="false"          embedded="true"  />
      <font basename="MS-PGothic"         name="MDOMCG+MS-PGothic"
            type="Type0"                  vertical="false"          embedded="true"  />
      <font basename="MS-PGothic"         name="MDOMCG+MS-PGothic"
            type="Type0"                  vertical="true"           embedded="true"  />
      <font basename="MS-PMincho"         name="MEKHMP+MS-PMincho"
            type="Type0"                  vertical="false"          embedded="true"  />
      <font basename="TimesNewRomanPSMT"  name="TimesNewRomanPSMT"
            type="TrueType"               vertical="false"          embedded="false" />
    </fonts>

Because the XML file contains all subsets of a font it might differ from what Adobe Reader® shows.
