Function Documentation

Evas_Coord evas_coord_screen_x_to_world	(	const Evas_Canvas *	obj,
		int	x
	)

Convert/scale an output screen co-ordinate into canvas co-ordinates.

Since :: 2.3

Returns:: The screen co-ordinate translated to canvas unit co-ordinates

Remarks:

This function takes in a horizontal co-ordinate as the x parameter and converts it into canvas units, accounting for output size, viewport size and location, returning it as the function return value. If e is invalid, the results are undefined.

Example:

 extern Evas *evas;
 extern int screen_x;
 Evas_Coord canvas_x;

 canvas_x = evas_coord_screen_x_to_world(evas, screen_x);

Parameters:

[in]	obj	The canvas object
[in]	x	The screen/output x co-ordinate

Evas_Coord evas_coord_screen_y_to_world	(	const Evas_Canvas *	obj,
		int	y
	)

Convert/scale an output screen co-ordinate into canvas co-ordinates.

Since :: 2.3

Returns:: The screen co-ordinate translated to canvas unit co-ordinates

Remarks:

This function takes in a vertical co-ordinate as the y parameter and converts it into canvas units, accounting for output size, viewport size and location, returning it as the function return value. If e is invalid, the results are undefined.

Example:

 extern Evas *evas;
 extern int screen_y;
 Evas_Coord canvas_y;

 canvas_y = evas_coord_screen_y_to_world(evas, screen_y);

Parameters:

[in]	obj	The canvas object
[in]	y	The screen/output y co-ordinate

int evas_coord_world_x_to_screen	(	const Evas_Canvas *	obj,
		Evas_Coord	x
	)

Convert/scale a canvas co-ordinate into output screen co-ordinates.

Since :: 2.3

Returns:: The output/screen co-ordinate translated to output co-ordinates

Remarks:

This function takes in a horizontal co-ordinate as the x parameter and converts it into output units, accounting for output size, viewport size and location, returning it as the function return value. If e is invalid, the results are undefined.

Example:

 extern Evas *evas;
 int screen_x;
 extern Evas_Coord canvas_x;

 screen_x = evas_coord_world_x_to_screen(evas, canvas_x);

Parameters:

[in]	obj	The canvas object
[in]	x	The canvas x co-ordinate

int evas_coord_world_y_to_screen	(	const Evas_Canvas *	obj,
		Evas_Coord	y
	)

Convert/scale a canvas co-ordinate into output screen co-ordinates.

Since :: 2.3

Returns:: The output/screen co-ordinate translated to output co-ordinates

Remarks:

This function takes in a vertical co-ordinate as the x parameter and converts it into output units, accounting for output size, viewport size and location, returning it as the function return value. If e is invalid, the results are undefined.

Example:

 extern Evas *evas;
 int screen_y;
 extern Evas_Coord canvas_y;

 screen_y = evas_coord_world_y_to_screen(evas, canvas_y);

Parameters:

[in]	obj	The canvas object
[in]	y	The canvas y co-ordinate
