-
- A scale grid uses 4 grid lines (2 horizontal and 2 vertical) to break an image into 9 sections, as shown below:
-
- \image declarative-scalegrid.png
-
- When the image is scaled:
- \list
- \i the corners (sections 1, 3, 7, and 9) are not scaled at all
- \i the middle (section 5) is scaled both horizontally and vertically
- \i sections 2 and 8 are scaled horizontally
- \i sections 4 and 6 are scaled vertically
- \endlist
-
- Each scale grid property (left, right, top, and bottom) specifies an offset from the respective side. For example, \c scaleGrid.bottom="10" sets the bottom scale grid line 10 pixels up from the bottom of the image.
-
- A scale grid can also be specified using a
- \l {Image::source}{.sci file}.
