void evas_output_size_set | ( | Evas * | e, |
int | w, | ||
int | h | ||
) |
Sets the output size of the render engine of the given evas.
The evas will render to a rectangle of the given size once this function is called. The output size is independent of the viewport size. The viewport will be stretched to fill the given rectangle.
The units used for w
and h
depend on the engine used by the evas.
e | The given evas. |
w | The width in output units, usually pixels. |
h | The height in output units, usually pixels. |

Retrieve the output size of the render engine of the given evas.
The output size is given in whatever the output units are for the engine.
If either w
or h
is NULL
, then it is ignored. If e
is invalid, the returned results are undefined.
e | The given evas. |
w | The pointer to an integer to store the width in. |

Sets the output viewport of the given evas in evas units.
The output viewport is the area of the evas that will be visible to the viewer. The viewport will be stretched to fit the output target of the evas when rendering is performed.
e | The given evas. |
x | The top-left corner x value of the viewport. |
y | The top-left corner y value of the viewport. |

Calling this function writes the current canvas output viewport size and location values into the variables pointed to by x
, y
, w
and h
. On success the variables have the output location and size values written to them in canvas units. Any of x
, y
, w
or h
that are NULL
will not be written to. If e
is invalid, the results are undefined.

Sets the output framespace size of the render engine of the given evas.
The framespace size is used in the Wayland engines to denote space where the output is not drawn. This is mainly used in ecore_evas to draw borders
The units used for w

depend on the engine used by the evas.
e | The given evas. |
