Q: Options of flip book printing area
A: Read the following direction and you will find it's very easy to do.
I’ve set some printing area in the flash pamphlet, but in the page, they are hard to be seen. I mean they are already totally transparent, so can I make it more visible?
Please your sight to the right side window after you draw the area for print. The area is transparent might be because the “over alpha” value is too low, just increase it to fit.
*Please be aware that you have to click “Apply Changes” to apply any changes to the flash book.
