[jira] [Updated] (PDFBOX-3099) Find suitable PDFont
[ https://issues.apache.org/jira/browse/PDFBOX-3099?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
David KELLER updated PDFBOX-3099:
---------------------------------
Description:
What is the best way to find a suitable font ?
I assume that PDFont cannot load directly a java.awt.Font.
But I want to parse a PDF and find a text occurrence using "TextPosition textStart;"
A this moment I can retrieve the good font using :
float fontSize = textStart.getFontSize();
PDFont font = textStart.getFont();
But in the PDF, the font is not complete (partial incorporated font).
So If I want to replace "#date#" by "10 Novembre 2015", i can have this result "1? Novembre 2?1?". Because "0" is not present in the "partial incorporated font"
So I need to determine the font used and find on the server the TTF font source, and then load it using .
I found on forums this thread http://stackoverflow.com/questions/13077611/how-to-retrieve-the-native-font-name-in-java
Then I wrote this source code to "do the job"
{code}
public static PDFont findSuitableFont(PDDocument pdDocument, PDFont font) {
String fontName = font.getFontDescriptor().getFontName();
fontName = fontName.replace("+", "");
fontName = fontName.replace("ABCDEE", "");
GraphicsEnvironment graphicsEnvironment = GraphicsEnvironment.getLocalGraphicsEnvironment();
Font[] fonts = graphicsEnvironment.getAllFonts(); // Get the fonts
for (Font existingFont : fonts) {
if (existingFont.getFontName().equals(fontName)) {
try {
return getPDFont(existingFont, pdDocument);
} catch (Exception e) {
e.printStackTrace();
}
}
}
return null;
}
public static PDFont getPDFont(Font font, PDDocument pdDocument)
throws NoSuchFieldException, SecurityException, IllegalArgumentException, IllegalAccessException,
InvocationTargetException, NoSuchMethodException, IOException
{
Method method = font.getClass().getDeclaredMethod("getFont2D");
method.setAccessible(true);
Font2D f = (Font2D) method.invoke(font);
return getPDFont(f, pdDocument);
}
public static PDFont getPDFont(Font2D font, PDDocument pdDocument)
throws NoSuchFieldException, SecurityException, IllegalArgumentException, IllegalAccessException, IOException {
if (font instanceof CompositeFont) {
System.out.println("Font '" + font.getFontName(Locale.getDefault()) + "' is composed of:");
CompositeFont cf = (CompositeFont) font;
PDFont pdFont = null;
for (int i = 0; i < cf.getNumSlots(); i++) {
PhysicalFont pf = cf.getSlotFont(i);
pdFont = getPDFont(pf, pdDocument);
if (pdFont != null) {
return pdFont;
}
}
} else {
Field platName = PhysicalFont.class.getDeclaredField("platName");
platName.setAccessible(true);
String fontPath = (String)platName.get(font);
platName.setAccessible(false);
System.out.println("-> " + font);
System.out.println("fontPath: " + fontPath);
return PDTrueTypeFont.loadTTF(pdDocument, fontPath);
}
return null;
}
protected void findSuitableFont(TextPosition textStart) {
float fontSize = textStart.getFontSize();
PDFont font = textStart.getFont();
logger.info("fontSize: " + fontSize);
logger.info("font: " + font.getBaseFont());
PDFont pdFont = findSuitableFont(document, font);
logger.info("suitable font: " + pdFont.getBaseFont());
}
{code}
