* Default constructor: creates a DistortedBitmap (width,height) pixels in size, with the distortion

36
|
* grid of 'cols' and does not fill it up with any Bitmap data just yet.
|
|
37
|
* <p>
|
|
38
|
* Distortion grid is a grid of rectangles the Bitmap is split to. The vertices of this grid are then
|
|
39
|
* moved around by the Vertex Shader to create various Vertex Effects.
|
|
40
|
* <p>
|
|
41
|
* Size parameter describes the horizontal size, i.e. the number of rectangles the top (or bottom) edge
|
|
42
|
* is split to. So when size=1, the whole Bitmap is just one giant rectangle. When size=10, the Bitmap
|
|
43
|
* is split into a grid of 10x10 rectangles.
|
|
44
|
* <p>
|
|
45
|
* The higher the size, the better Vertex Effects look; on the other hand too high size will slow things
|
|
46
|
* down.

* @param width width of the DistortedBitmap, in pixels.

* @param cols Number of columns in the distortion grid. 2<=size<256.
|

|
* Number of rows gets calculated with 'rows = cols*height/width'.
