Returns the maximum allowed width for bitmaps drawn with this canvas.

Usage

From source file:Main.java

/**
 * This method calculates maximum size of both width and height of bitmap.
 * It is twice the device screen diagonal for default implementation (extra quality to zoom image).
 * Size cannot exceed max texture size.//from   w w  w . ja  v a2  s .  c  om
 *
 * @return - max bitmap size in pixels.
