What types of images would you want to use 9 slice scaling with VS. the ordinary transform tool? Is the idea behind 9 slice scaling to scale an image larger than it was designed to go and to use this tool to specify parts of the image to not scale up? Using my attached image, if I wanted to not scale up the text, would I place the text in the center area so the text does not scale up and become distorted? Is that how this tool works?
Here are some resources on 9-slice scaling:
Following the 3rd tutorial you recommended on this page http://www.adobe.com/devnet/fireworks/articles/9-slice_scaling.html with the photographer taking a photo in the orangish background -- I understand that traditionally scaling the background will distort the photographer, however, I'm confused by why the vertical guides are being placed around that small section of text in the attached second image. Why this spot, and why does the text not get distorted at all after applying the transform? I guess I'm still missing how this tool works. I was able to use the tool successfully following this tutorial, I just do not understand the concept of what it is doing.
In that example, the layout was being scaled horizontally—i.e., stretched wider. The placement of the guides between the photographer's silhouhette and the sun allowed that narrow part of the image to be stretched without affecting the components on either side. The text isn't distorted because 9-slice scaling affects the bounding box of the text—making it wider here—not the text itself.
I believe that 9-slice scaling was intended originally for scaling interface elements like buttons, the corners of which become distorted when using the standard Scale/Transform tools. Here's how I understand 9-slice scaling:
