ID3DXFont interface

The ID3DXFont interface encapsulates the textures and resources needed to render a specific font on a specific device.

Members

The ID3DXFont interface inherits from the IUnknown interface. ID3DXFont also has these types of members:

Methods

The ID3DXFont interface has these methods.

MethodDescription
DrawText

Draws formatted text. This method supports ANSI and Unicode strings.

GetDC

Returns a handle to a display device context (DC) that has the font set.

GetDesc

Gets a description of the current font object. GetDescW and GetDescA are identical to this method, except that a pointer is returned to a D3DXFONT_DESCW or D3DXFONT_DESCA structure, respectively.

GetDevice

Retrieves the Direct3D device associated with the font object.

GetGlyphData

Returns information about the placement and orientation of a glyph in a character cell.

GetTextMetrics

Retrieves font characteristics that are identified in a TEXTMETRIC structure. This method supports ANSI and Unicode compiler settings.

OnLostDevice

Use this method to release all references to video memory resources and delete all stateblocks. This method should be called whenever a device is lost, or before resetting a device.

OnResetDevice

Use this method to re-acquire resources and save initial state.

PreloadCharacters

Loads a series of characters into video memory to improve the efficiency of rendering to the device.

PreloadGlyphs

Loads a series of glyphs into video memory to improve the efficiency of rendering to the device.

PreloadText

Loads formatted text into video memory to improve the efficiency of rendering to the device. This method supports ANSI and Unicode strings.

 

Remarks

The ID3DXFont interface is obtained by calling D3DXCreateFont or D3DXCreateFontIndirect.

The LPD3DXFONT type is defined as a pointer to the ID3DXFont interface.
