Function Documentation

GooeyCanvas_Create()

GooeyCanvas * GooeyCanvas_Create	(	int	x,
		int	y,
		int	width,
		int	height
	)

Adds a canvas to the specified window.

This function creates a new GooeyCanvas and attaches it to the given GooeyWindow at the specified coordinates and dimensions.

Parameters

x	The x-coordinate of the canvas position.
y	The y-coordinate of the canvas position.
width	The width of the canvas.
height	The height of the canvas.

Returns

A pointer to the newly created GooeyCanvas.

GooeyCanvas_DrawArc()

void GooeyCanvas_DrawArc	(	GooeyCanvas *	canvas,
		int	x_center,
		int	y_center,
		int	width,
		int	height,
		int	angle1,
		int	angle2
	)

Draws an arc onto the user-defined canvas.

The arc is drawn within the specified bounding box and between the given angles.

Parameters

canvas	The user-defined canvas.
x_center	The x-coordinate of the arc's center.
y_center	The y-coordinate of the arc's center.
width	The width of the arc's bounding box.
height	The height of the arc's bounding box.
angle1	The starting angle of the arc in degrees.
angle2	The ending angle of the arc in degrees.

GooeyCanvas_DrawLine()

void GooeyCanvas_DrawLine	(	GooeyCanvas *	canvas,
		int	x1,
		int	y1,
		int	x2,
		int	y2,
		unsigned long	color_hex
	)

Draws a line onto the user-defined canvas.

Parameters

canvas	The user-defined canvas.
x1	The x-coordinate of the starting point of the line.
y1	The y-coordinate of the starting point of the line.
x2	The x-coordinate of the ending point of the line.
y2	The y-coordinate of the ending point of the line.
color_hex	The color of the line in hexadecimal format.

GooeyCanvas_DrawRectangle()

void GooeyCanvas_DrawRectangle	(	GooeyCanvas *	canvas,
		int	x,
		int	y,
		int	width,
		int	height,
		unsigned long	color_hex,
		bool	is_filled
	)

Draws a rectangle onto the user-defined canvas.

The rectangle can be either filled with a solid color or outlined.

Parameters

canvas	The user-defined canvas.
x	The x-coordinate of the rectangle's top-left corner.
y	The y-coordinate of the rectangle's top-left corner.
width	The width of the rectangle.
height	The height of the rectangle.
color_hex	The color of the rectangle in hexadecimal format.
is_filled	If true, the rectangle is filled with a solid color; otherwise, it is hollow.

GooeyCanvas_SetForeground()

void GooeyCanvas_SetForeground	(	GooeyCanvas *	canvas,
		unsigned long	color_hex
	)

Sets the foreground color of the user-defined canvas.

The foreground color is used for subsequent drawing operations.

Parameters

canvas	The user-defined canvas.
color_hex	The foreground color in hexadecimal format.
