Detailed Description

The graphics context itself.

Typedef Documentation

n_GContext

typedef struct n_GContext n_GContext

Internal representation of the graphics context itself. Created via n_graphics_context_from_buffer() or n_graphics_context_from_graphics_context().

Function Documentation

n_graphics_context_begin()

void n_graphics_context_begin

(

n_GContext *

ctx

)

In Pebble OS, use this before drawing to the n_GContext for contexts created from a graphics context (via n_graphics_context_from_graphics_context()). Not required on other platforms.

n_graphics_context_destroy()

void n_graphics_context_destroy

(

n_GContext *

ctx

)

Destroys a n_GContext.

n_graphics_context_end()

void n_graphics_context_end

(

n_GContext *

ctx

)

In Pebble OS, use this before drawing to the n_GContext for contexts created from a graphics context (via n_graphics_context_from_graphics_context()). Not required on other platforms.

n_graphics_context_from_buffer()

n_GContext* n_graphics_context_from_buffer

(

uint8_t *

buf

)

Creates a n_GContext based on a framebuffer.

n_graphics_context_from_graphics_context()

n_GContext* n_graphics_context_from_graphics_context

(

GContext *

ctx

)

Creates a n_GContext based on a GContext (provided by Pebble OS).

n_graphics_context_set_antialiased()

void n_graphics_context_set_antialiased	(	n_GContext *	ctx,
		bool	antialias
	)

Sets whether antialiasing should be used.

Note

Not implemented yet.

n_graphics_context_set_fill_color()

void n_graphics_context_set_fill_color	(	n_GContext *	ctx,
		n_GColor	color
	)

Sets the n_GColor used to fill primitives.

n_graphics_context_set_stroke_caps()

void n_graphics_context_set_stroke_caps	(	n_GContext *	ctx,
		bool	caps
	)

Sets whether stroke caps should be drawn.

n_graphics_context_set_stroke_color()

void n_graphics_context_set_stroke_color	(	n_GContext *	ctx,
		n_GColor	color
	)

Sets the n_GColor used to draw strokes.

n_graphics_context_set_stroke_width()

void n_graphics_context_set_stroke_width	(	n_GContext *	ctx,
		uint16_t	width
	)

Sets the stroke width.

n_graphics_context_set_text_color()

void n_graphics_context_set_text_color	(	n_GContext *	ctx,
		n_GColor	color
	)

Sets the n_GColor used to draw text.
