a .9 guide is a stretchable png file.. take when you are typing a message for example, the more you type, the bigger the box gets. the guides tell it how to stretch and make sure it doesn't look like crap when its stretching. If you edit a .9.png, you need to put the guides back on using the draw9patch tool.
Thank you xkape, that makes sense....so know I gotta learn how to use the draw9patch tool? Man it never ends.:icon_eek:
