-GUIs often feature elements that are context sensitive in regard to their size: panels and dialogs that need to be resized to fit the containing content. These may cause visual problems when you apply texturing to the resized node.

-Normally, the engine scales the texture to fit the boundaries of a box node, but by defining slice-9 edge areas it is possible to limit what parts of the texture that should scale:

-The *Slice9* box node consists of 4 numbers that specify the number of pixels for the left, top, right and bottom margin that should not be regularly scaled:

-- Corner segments are never scaled.
-- Edge segments are scaled along a single axis. The left and right edge segments are scaled vertically. The top and bottom edge segments are scaled horizontally.
-- The central texture area is scaled horizontally and vertically as needed.

-The *Slice9* texture scaling described above is only applied when you change box node's size:

-
-If you change scale parameter of the box node - the node and texture is scaled without applying *Slice9* parameters.
-
-Due to the way mipmapping works in the renderer, scaling of texture segments can sometimes exhibit artifacts. This happens when you _scale down_ segments below the original texture size. The renderer then selects a lower resolution mipmap for the segment, resulting in visual artifacts.

+## Slice-9 texturing
+
+GUI box nodes and Sprite components sometimes feature elements that are context sensitive in regard to their size: panels and dialogs that need to be resized to fit the containing content or a health bar that need to be resized to show the remaining health of an enemy. These may cause visual problems when you apply texturing to the resized node or sprite.

+Normally, the engine scales the texture to fit the rectangular boundaries, but by defining slice-9 edge areas it is possible to limit what parts of the texture that should scale:
