GetTranslate()

const CVector2D& CTextRenderer::GetTranslate ( ) const

inline

PrintfAdvance()

void CTextRenderer::PrintfAdvance	(	const wchar_t *	fmt,
			...
	)

Print formatted text at (0,0) under the current transform, and advance the transform by the width of the text.

PrintfAt()

void CTextRenderer::PrintfAt	(	float	x,
		float	y,
		const wchar_t *	fmt,
			...
	)

Print formatted text at (x,y) under the current transform.

Does not alter the current transform.

Put() [1/3]

void CTextRenderer::Put	(	float	x,
		float	y,
		const wchar_t *	buf
	)

Print text at (x,y) under the current transform.

Does not alter the current transform.

Put() [2/3]

void CTextRenderer::Put	(	float	x,
		float	y,
		const char *	buf
	)

Print text at (x,y) under the current transform.

Does not alter the current transform. buf must be a UTF-8 string.

Put() [3/3]

void CTextRenderer::Put	(	float	x,
		float	y,
		const std::wstring *	buf
	)

Print text at (x,y) under the current transform.

Does not alter the current transform. buf must remain valid until Render() is called. (This should be used to minimise memory copies when possible.)

PutAdvance()

void CTextRenderer::PutAdvance

(

const wchar_t *

buf

)

Print text at (0,0) under the current transform, and advance the transform by the width of the text.

PutString()

void CTextRenderer::PutString ( float  x, float  y, const std::wstring *  buf, bool  owned  )

private

Render()

void CTextRenderer::Render	(	Renderer::Backend::IDeviceCommandContext *	deviceCommandContext,
		Renderer::Backend::IShaderProgram *	shader,
		const CVector2D &	transformScale,
		const CVector2D &	translation
	)

Render all of the previously printed text calls.

ResetTranslate()

void CTextRenderer::ResetTranslate

(

const CVector2D &

translate = CVector2D{}

)

Reset the text transform to the default, with (0,0) in the top-left corner.

SetClippingRect()

void CTextRenderer::SetClippingRect

(

const CRect &

rect

)

Set clipping rectangle, in pre-transform coordinates (i.e.

text is clipped against this rect based purely on the x,y values passed into Put()). Text fully outside the clipping rectangle may not be rendered. Should be used in conjunction with SetScissors for precise clipping - this is just an optimisation.

SetCurrentColor()

void CTextRenderer::SetCurrentColor

(

const CColor &

color

)

Set the color for subsequent print calls.

SetCurrentFont()

void CTextRenderer::SetCurrentFont

(

CStrIntern

font

)

Set the font for subsequent print calls.

Translate()

void CTextRenderer::Translate	(	float	x,
		float	y
	)
