TRSGPFont Class

Encapsulates the characteristics, such as family, height, size, and style (or combination of styles), of a specific font. A Font object is used when drawing strings.

Namespace: RSGdiPlusGraphics

	Name	Description
	Create(TRSGPCanvas)	Constructs the graphics object. Specify the canvas that owns the graphics object. (Overrides RSGdiPlusGraphics.TRSGPGraphicsObject.Create(TRSGPCanvas).)
	Destroy	Represents the destructor of the TRSGPFont class. (Overrides RSGdiPlusGraphics.TRSGPGraphicsObject.Destroy.)

Name

Description

public property

Brush

Specifies the brush that controls the painting of the font.

public property

CellAscent

Returns the cell ascent, in design units, of this font family for the specified style or style combination.

public property

CellDescent

Returns the cell descent, in design units, of this font family for the specified style or style combination.

published property

Color

Specifies the color of the font

public property

EmHeight

Returns the size (commonly called em size or em height), in design units, of this font family.

public property

FontFamily

Returns the font family on which this font is based.

published property

FontUnit

Specifies the unit of measure of this Font object.

public property

Handle

Handle of the graphics object, used by the MS GDI+ flat API routines (Inherited from RSGdiPlusGraphics.TRSGPGraphicsObject.)

public property

Height

Returns the line spacing, in pixels, of this font. The line spacing is the vertical distance between the base lines of two consecutive lines of text. Thus, the line spacing includes the blank space between lines along with the height of the character itself.

public property

LineSpacing

Returns the line spacing, in design units, of this font family for the specified style or style combination. The line spacing is the vertical distance between the base lines of two consecutive lines of text.

published property

Name

Specifies the name of the font. Change the name to change the font used.

public property

OnChange

Occurs when the graphics object changes.

Note
There are two events that are exactly the same, OnChanged and OnChange. The extra event name is to allow easier transition from other Delphi libraries, either the VCL (OnChanged) or FMX (OnChange) libraries. Use either one as needed. Only one event is triggered.

public property

OnChanged

Occurs when the graphics object changes.

Note
There are two events that are exactly the same, OnChanged and OnChange. The extra event name is to allow easier transition from other Delphi libraries, either the VCL (OnChanged) or FMX (OnChange) libraries. Use either one as needed. Only one event is triggered.

public property

Owner

Canvas that owns the object. The Canvas will free this graphics object if it is destroyed. However, to keep memory use under control, it is recommended that you free graphics objects when you are finished with them. (Inherited from RSGdiPlusGraphics.TRSGPGraphicsObject.)

published property

Quality

Specifies the text rendering quality to use when drawing text with this font

published property

Size

Specifies the size, in units, of the font

published property

Style

Specifies the style (italic, bold, etc) of this font's typeface.

	Name	Description
	Assign(GpFont)	Overloaded. Copy GDI+ font to the current font object.
	Assign(TPersistent)	Overloaded. Represents method Assign(TPersistent).
	AssignTo(TPersistent)	Represents method AssignTo(TPersistent).
	Changed	Call this method when the graphics object changes. It triggers an OnChange event. (Inherited from RSGdiPlusGraphics.TRSGPGraphicsObject.)
	Clone	Creates a copy of the graphics object (Inherited from RSGdiPlusGraphics.TRSGPGraphicsObject.)
	GetFont(GpFontFamily)	Represents method GetFont(GpFontFamily).
	GetFontStyle(Integer)	Overloaded. Returns an integer value that is an element of the Style enumeration or the result of a bitwise OR applied to two or more elements of the Style enumeration.
	GetFontStyle(TRSGPFontStyles)	Overloaded. Returns a set of TRSGPFontStyle based on the integer input
	GetHandle	Call this method to acquire a handle from the GDI+ flat API library (Overrides RSGdiPlusGraphics.TRSGPGraphicsObject.GetHandle.)
	GetLogFontA	Returns a LOGFONTA record containing the attributes of this Font object.
	GetLogFontW	Returns a LOGFONTA record containing the attributes of this Font object.
	IsFontFamilyAvailable(String)	Returns true if a font with the specified name is available to use.
	Notification(TRSGPCanvas)	Called when the Canvas is releasing control of the graphics object. The canvas will no longer be responsible for freeing the graphics object. (Inherited from RSGdiPlusGraphics.TRSGPGraphicsObject.)
	ObjectChanged(TObject)	Represents method ObjectChanged(TObject).
	Prepare(TRectF,Single)	Prepare the graphics object for drawing. Graphics objects respond in this method to upcoming calls. For example, gradient brushes can make sure the gradient will cover the entire rectangle. (Overrides RSGdiPlusGraphics.TRSGPGraphicsObject.Prepare(TRectF,Single).)
	QueryInterface(TGUID,Void)	Represents method QueryInterface(TGUID,Void). (Inherited from RSGdiPlusGraphics.TRSGPGraphicsObject.)
	ReleaseHandle	Releases the underlying GDI+ object back to the GDI+ library. (Overrides RSGdiPlusGraphics.TRSGPGraphicsObject.ReleaseHandle.)
	Update	Update native graphics object (Inherited from RSGdiPlusGraphics.TRSGPGraphicsObject.)
	_AddRef	Represents method _AddRef. (Inherited from RSGdiPlusGraphics.TRSGPGraphicsObject.)
	_Release	Represents method _Release. (Inherited from RSGdiPlusGraphics.TRSGPGraphicsObject.)
