Font (openjfx 8.0.202 API)

java.lang.Object
- javafx.scene.text.Font

```
public final class Font
extends Object
```
The Font class represents fonts, which are used to render text on screen.
The size of a Font is described as being specified in points which are a real world measurement of approximately 1/72 inch.
Given that fonts scale with the rendering transform as determined by the transform attributes of a Node using the Font and its ancestors, the size will actually be relative to the local coordinate space of the node, which should provide coordinates similar to the size of a point if no scaling transforms are present in the environment of the node. Note that the real world distances specified by the default coordinate system only approximate point sizes as a rule of thumb and are typically defaulted to screen pixels for most displays.
For more information see Node for more information on the default coordinate system

Since:

JavaFX 2.0

    Parameters:
    
    family - The family of the font
    
    size - The point size of the font. This can be a fractional value, but must not be negative. If the size is < 0 the default size will be used.

  - font
```
public static Font font(String family)
```
    Searches for an appropriate font based on the given font family name and default font size. This method is not guaranteed to return a specific font, but does its best to find one that fits the specified requirements. A null or empty value for family allows the implementation to select any suitable font.
    
    Parameters:
    
    family - The family of the font
    
    Returns:
    
    The font that best fits the specified requirements.
  - font
```
public static Font font(double size)
```
    Searches for an appropriate font based on the default font family name and given font size. This method is not guaranteed to return a specific font, but does its best to find one that fits the specified requirements.
    
    Parameters:
    
    size - The point size of the font. This can be a fractional value, but must not be negative. If the size is < 0 the default size will be used.
    
    Returns:
    
    The font that best fits the specified requirements.
  - getName
```
public final String getName()
```
    The full font name. This name includes both the family name and the style variant within that family. For example, for a plain Arial font this would be "Arial Regular" and for a bolded Arial font this would be "Arial Bold". The precise name to use when loading a font is defined within each font file as the full font name. For example, "Proxima Nova ExtraCondensed Bold Italic" would refer to a specific Proxima Nova font. A null or empty name allows the implementation to select any suitable font.
    There is a single unified way to load all of application supplied (via Font.loadFont(), JavaFX runtime delivered fonts, and system installed fonts. Simply create the font by specifying the full name of the font you want to load. If the specific font cannot be located, then a fallback or default font will be used. The "name" will be updated to reflect the actual name of the font being used. A load failure condition can be discovered by checking the name of the Font with the name you tried to load.
    Note that if you wish to locate a font by font family and style then you can use one of the font(java.lang.String, javafx.scene.text.FontWeight, javafx.scene.text.FontPosture, double) factory methods defined in this class.
  - getFamily
```
public final String getFamily()
```
    Returns the family of this font.
    
    Returns:
    
    The family of this font.
  - getStyle
```
public final String getStyle()
```
    The font specified string describing the style within the font family.
    
    Returns:
    
    The style name of this font.
  - getSize
```
public final double getSize()
```
    The point size for this font. This may be a fractional value such as 11.5. If the specified value is < 0 the default size will be used.
  - loadFont
```
public static Font loadFont(String urlStr,
                            double size)
```
    Loads a font resource from the specified URL. If the load is successful such that the location is readable, and it represents a supported font format then a Font object will be returned.
    If the application does not have the proper permission then this method will return the default system font with the specified font size.
    Any failure such as a malformed URL being unable to locate or read from the resource, or if it doesn't represent a font, will result in a null return. It is the application's responsibility to check this before use.
    On a successful (non-null) return the font will be registered with the FX graphics system for creation by available constructors and factory methods, and the application should use it in this manner rather than calling this method again, which would repeat the overhead of downloading and installing the font.
    The font size parameter is a convenience so that in typical usage the application can directly use the returned (non-null) font rather than needing to create one via a constructor. Invalid sizes are those <=0 and will result in a default size.
    If the URL represents a local disk file, then no copying is performed and the font file is required to persist for the lifetime of the application. Updating the file in any manner will result in unspecified and likely undesired behaviours.
    
    Parameters:
    
    urlStr - from which to load the font, specified as a String.
    
    size - of the returned font.
    
    Returns:
    
    the Font, or null if the font cannot be created.
  - loadFont
```
public static Font loadFont(InputStream in,
                            double size)
```
    Loads a font resource from the specified input stream. If the load is successful such that the stream can be fully read, and it represents a supported font format then a Font object will be returned.
    If the application does not have the proper permission then this method will return the default system font with the specified font size.
    Any failure such as abbreviated input, or an unsupported font format will result in a null return. It is the application's responsibility to check this before use.
    On a successful (non-null) return the font will be registered with the FX graphics system for creation by available constructors and factory methods, and the application should use it in this manner rather than calling this method again, which would repeat the overhead of re-reading and installing the font.
    The font size parameter is a convenience so that in typical usage the application can directly use the returned (non-null) font rather than needing to create one via a constructor. Invalid sizes are those <=0 and will result in a default size.
    This method does not close the input stream.
    
    Parameters:
    
    in - stream from which to load the font.
    
    size - of the returned font.
    
    Returns:
    
    the Font, or null if the font cannot be created.
  - toString
```
public String toString()
```
    Converts this Font object to a String representation. The String representation is for informational use only and will change. Do not use this string representation for any programmatic purpose.
    
    Overrides:
    
    toString in class Object
  - equals
```
public boolean equals(Object obj)
```
    Indicates whether some other object is "equal to" this one.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    obj - the reference object with which to compare.
    
    Returns:
    
    true if this object is equal to the obj argument; false otherwise.
  - hashCode
```
public int hashCode()
```
    Returns a hash code for this Font object.
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    a hash code for this Font object.
