getFirstPixel(direction) → {object}
Scans the BitmapData, pixel by pixel, until it encounters a pixel that isn't transparent (i.e. has an alpha value > 0).
It then stops scanning and returns an object containing the color of the pixel in r, g and b properties and the location in the x and y properties.
The direction parameter controls from which direction it should start the scan:
0 = top to bottom
1 = bottom to top
2 = left to right
3 = right to left
Parameters
| Name | Type | Argument | Default | Description |
|---|---|---|---|---|
direction | number | <optional> | 0 | The direction in which to scan for the first pixel. 0 = top to bottom, 1 = bottom to top, 2 = left to right and 3 = right to left. |
Returns
object -
Returns an object containing the color of the pixel in the r, g and b properties and the location in the x and y properties.
