void drawFilledRect	(	const Rect &	rect,
		unique_id	imageId
	)

Draws a filled rectangle with an image texture

Parameters

rect	The rectangle to draw
imageId	The unique ID of the image to use

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

Draws a filled rectangle with an optional texture

Parameters

y	The y-coordinate of the rectangle
w	The width of the rectangle
h	The height of the rectangle
imageId	The unique ID of the image 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

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

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
