I had a similar issue with a drop shadow that threw off the text. Since the image was created I put a clear text box on top. Sometimes if you play with the font size and use something other than the center justification, it works out with a couple of blank lines and spaces strategically placed above or below.

Pronto edit sees all graphics as rectangles when it comes to adding text. The center of the rectangle is the center of the text. If you are creating fresh graphics that are not perfectly symmetrical , create a larger than usual canvas to start or expand it afterward. Then offset the crop it to accommodate the center of text. If you are using a drop shadow or highlight it is possible to use it as a separate image underneath.

For older graphics you can re-edit them by creating a new larger transparent image and paste the old image as a layer inside the new.

One trick you can use for 3-D text. Label a button with a large black bold text. Then create a transparent text box with the same text size and style but use a lighter color like yellow. Place it directly above the button text , then move it up 3 pixels and left 3 pixels. Depending on the colors used and the placement, the text could look like a cut-out or a block-letters. Swap the colors and it could look like a it has a highlight . Project Boredom has an example of this with an animation. [Link: remotecentral.com]
