/** Stores frame styles of an array of cells, supports merged ranges.
|
|
|
|
This class is able to store the frame styles of an array of cells and to
|
|
draw the entire array or parts of it to any output device.
|
|
|
|
Every cell contains the style of the left, right, top, bottom, top-left to
|
|
bottom-right, and bottom-left to top-right frame border.
|
|
|
|
On drawing, the thicker frame border of neighbored cells is selected
|
|
automatically. All borders are drawn "connected", that means, the correct
|
|
start and end coordinates of all lines of the borders are calculated,
|
|
especially, if they are drawn together with diagonal frame borders.
|
|
|
|
This array fully supports merged cell ranges. In a merged range, the frame
|
|
borders of the top-left cell is extended to the entire range, and all other
|
|
cells in that range are overlapped. Again, all connected frame borders,
|
|
also diagonals and frame borders from adjacent merged ranges, are handled
|
|
automatically.
|
|
|
|
Additionally, a clipping range can be set. If such a range is used, all
|
|
frame borders outside this range are completely ignored, and are not used
|
|
in the connected border calculation anymore.
|
|
|
|
The array can be mirrored in both directions. It is possible to specify,
|
|
whether to mirror the double frame styles, and whether to swap diagonal
|
|
frame borders.
