Member Function Documentation

void drawFilledRect ( const Rect & rect )

Draws a filled rectangle

Parameters

rect	The rectangle to draw

void drawFilledRect	(	const Rect &	rect,
		unique_id	texture
	)

Draws a filled rectangle with an image texture

Parameters

rect	The rectangle to draw
texture	The unique ID of the texture to use

void drawFilledRect	(	float	x,
		float	y,
		float	w,
		float	h,
		unique_id	texture = `INVALID_ID`
	)

Draws a filled rectangle with an optional texture

Parameters

x	The x-coordinate of the rectangle
y	The y-coordinate of the rectangle
w	The width of the rectangle
h	The height of the rectangle
texture	The unique ID of the texture to use (defaults to INVALID_ID)

void drawLine	(	const float2 &	start,
		const float2 &	end
	)

Draws a 1-fragment width line

Parameters

start	The starting point of the line
end	The ending point of the line

void drawText	(	const std::string &	text,
		Font &	font,
		float	fontScale,
		float	x,
		float	y
	)

Draws text on the screen

Parameters

text	The text string to draw
font	The font to use for drawing
fontScale	The scale of the font
x	The x-coordinate where the text starts
y	The y-coordinate where the text starts

auto getAspectRatio ( ) const

inline

Gets the aspect ratio of the renderer

Returns: The current aspect ratio

void resize ( const vireo::Extent & extent )

Resizes the renderer's viewport

Parameters

extent The new extent

auto setPenColor ( const float4 & color )

inline

Changes the color of the fragments for the next drawing commands

Parameters

color The new pen color

auto setTranslate ( const float2 & t )

inline

Changes the [x,y] translation for the next drawing commands

Parameters

t	The translation vector

auto setTransparency ( const float a )

inline

Changes the global transparency for the next drawing commands

The value is subtracted from the vertex alpha

Parameters

a	The transparency value
