ID3DXLine interface

The ID3DXLine interface implements line drawing using textured triangles.

Members

The ID3DXLine interface inherits from the IUnknown interface. ID3DXLine also has these types of members:

The ID3DXLine interface has these methods.

Method	Description
Begin	Prepares a device for drawing lines.
Draw	Draws a line strip in screen space. Input is in the form of an array that defines points (of D3DXVECTOR2) on the line strip.
DrawTransform	Draws a line strip in screen space with a specified input transformation matrix.
End	Restores the device state to how it was when ID3DXLine::Begin was called.
GetAntialias	Gets the line antialiasing state.
GetDevice	Retrieves the Direct3D device associated with the line object.
GetGLLines	Gets the OpenGL-style line-drawing mode.
GetPattern	Gets the line stipple pattern.
GetPatternScale	Gets the stipple-pattern scale value.
GetWidth	Gets the thickness of the line.
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.
SetAntialias	Toggles line antialiasing.
SetGLLines	Toggles the mode to draw OpenGL-style lines.
SetPattern	Applies a stipple pattern to the line.
SetPatternScale	Stretches the stipple pattern along the line direction.
SetWidth	Specifies the thickness of the line.

Create a line drawing object with D3DXCreateLine.

The LPD3DXLINE type is defined as a pointer to the ID3DXLine interface.
