Creates a FileInputStream by using the file descriptor fdObj, which represents an existing connection to an actual file in the file system.

Usage

From source file:Main.java

public static void main(String[] args) throws Exception {
    String fontFileName = "yourfont.ttf";
    InputStream is = new FileInputStream(fontFileName);

    Font ttfBase = Font.createFont(Font.TRUETYPE_FONT, is);

    Font ttfReal = ttfBase.deriveFont(Font.BOLD);
}

From source file:Main.java

public static void main(String[] args) throws Exception {
    String fontFileName = "yourfont.ttf";
    InputStream is = new FileInputStream(fontFileName);

    Font ttfBase = Font.createFont(Font.TRUETYPE_FONT, is);

    Font ttfReal = ttfBase.deriveFont(Font.PLAIN, 24);
}

From source file:Main.java
