Page.ReflowStart declared as:
public float ReflowStart( float width, float scale, boolean enable_images )

Code:

	 * @param width input width.
	 * @param scale scale base to 72 DPI, 2.0 means 144 DPI. the reflowed text will displayed in scale
	 * @param enable_images enable reflow images.
	 * @return the height that reflow required.

that mean, reflow function need you input a width value to layout.

if return 0, then ignore this page.
this mostly because the page has no element can be reflow.
for example: transparency group content will be ignored in reflow mode.

it is better, to create a new Activity.
derive from PDFLayout, may need to modify other related class, so not recommended.
