Field Detail

TRUETYPE_FONT

public static final int TRUETYPE_FONT

TrueType scalable font/typeface

See Also:

Constant Field Values

BITMAP_FONT

public static final int BITMAP_FONT

Bitmap font

See Also:

Constant Field Values

AGFA_FONT

public static final int AGFA_FONT

Intellifont Scalable font/typeface

See Also:

Constant Field Values

STORAGE_INTERNAL

public static final int STORAGE_INTERNAL

A printer comes with a standard set of internal fonts. The user can install additional fonts using cartridge or simms. Additional fonts can be downloaded to the printer during a print job. The location is a consideration when selecting a font.

Constant Field Values

STORAGE_SIMM

public static final int STORAGE_SIMM

See Also:

Constant Field Values

STORAGE_RAM

public static final int STORAGE_RAM

See Also:

Constant Field Values

symbolset

protected int symbolset

Font's symbolset. If this ia a bound font then then this field is set to symbolset's code else it is 0, and character complement number is used.

characterComplement

protected int[] characterComplement

For unbound font's character complement is use to check if a font can display desired symbol collection

typefaceFamily

protected int typefaceFamily

pitch

protected double pitch

style

protected int style

strokeWeight

protected int strokeWeight

cellHeight

protected int cellHeight

For bitmap fonts this is cell width. For truetype fonts it is units per em value

cellWidth

protected int cellWidth

For bitmap fonts this is cell height. For truetype fonts it is units per em value

isFixedPitch

protected boolean isFixedPitch

orientation

protected int orientation

Orientation characteristic. As we can rotate fonts this characteristics is not realley neaded

name

protected String name

Name of the font. This name is not used during font selection. ...

storage

protected int storage

One of storage constants. Specifies font's location

isPermanent

protected boolean isPermanent

This is applicapable for soft fonts only ( location == RAM ) true this font is permanent false this font is temporary For more information about temporary and permanent soft fonts refer to PCL Techincal Reference Soft Fonts

spaceDisplayable

protected boolean spaceDisplayable

Indicates whteher space character is displayable. As space character is widely used so we treat it a little bit different. This value is initialized at the the time the font is loaded.
