Specifies how the font should be looked up.

Applies only to device fonts.

The default value is flash.text.engine.FontLookup.DEVICE.

To set values for this property, use the following string values:

The name of the font to be used, or a comma-separated list of font names. Flash Player renders the element with the first available font in the list. For example "Arial, Helvetica, _sans" causes the player to search for "Arial", then "Helvetica" if Arial is not found, then _sans if neither is found.

Flash supports three generic device font names: _sans (similar to Helvetica and Arial), _serif (similar to Times Roman), and _typewriter (similar to Courier). These are mapped to specific device fonts depending on the platform.

The default value is "_serif".

Flash Player provides font fallback for glyphs which are not found in the selected font. Whether the font in use is embedded or device, if the glyph to be rendered is not found in the font, Flash Player attempts to render the glyph using another device font likely to contain the glyph.

Specifies the font posture to be used.

Applies only to device fonts.

The default value is flash.text.engine.FontPosture.NORMAL.

To set values for this property, use the following string values:

Specifies the font weight to be used.

Applies only to device fonts.

The default value is flash.text.engine.FontWeight.NORMAL.

To set values for this property, use the following string values:

The type of grid fitting used for this text. Use flash.text.GridFitType constants for this property. This property applies only if the flash.text.AntiAliasType property of the text is set to flash.text.AntiAliasType.ADVANCED.

The type of grid fitting used determines whether Flash Player forces strong horizontal and vertical lines to fit to a pixel or subpixel grid, or not at all.

Applies only to embedded fonts.

The default value is flash.text.GridFitType.PIXEL.

For the flash.text.GridFitType property, you can use the following string values:

The sharpness of the glyph edges in this text. This property applies only if the flash.text.AntiAliasType property is set to flash.text.AntiAliasType.ADVANCED. The range for sharpness is a number from -400 to 400. If you attempt to set sharpness to a value outside that range, Flash sets the property to the nearest value in the range (either -400 or 400).

Applies only to embedded fonts.

The default value is 0.0.

The thickness of the glyph edges in this text. This property applies only when flash.text.AntiAliasType is set to flash.text.AntiAliasType.ADVANCED.

The range for thickness is a number from -200 to 200. If you attempt to set thickness to a value outside that range, the property is set to the nearest value in the range (either -200 or 200).

Applies only to embedded fonts.

The default value is 0.0.

Creates a FontDescription object.

To change the font settings for the TextBlock, alter the FontDescription object properties and reassign it to the ElementFormat. and re-link the ElementFormat to the TextBlock. This will invalidate all the text lines in the TextBlock without changing their appearance. When the lines are re-broken, the new lines will have the new font settings.
