|
|
* window.setIcon( width, height, pixels )
|
|
*
|
|
* Change the window's icon.
|
|
*
|
|
* pixels must be an array of width x height pixels in 32-bits RGBA format. In the ruby binding the array will be
|
|
* flattened so you can have array's up to 3 dimensions(or more) to represent each pixel component. The size of the
|
|
* array will be assumed to be width * height * 4.
|
|
*
|
|
* The OS default icon is used by default.
|
|
*
|
|
* Usage example:
|
|
* pixels = [
|
|
* [[255, 0, 0, 255], [0, 0, 255, 255]],
|
|
* [[0, 255, 0, 255], [0, 0, 0, 255]]
|
|
* ]
|
|
*
|
|
* window.setIcon( 2, 2, pixels )
