Ornamental drawing is used to draw symmetrycal patterns or ornaments. Free hand drawing is simply repeated according to given symmetry method. Some ornaments are drawn imediately (2D Symmetry), while others are created after mouse button is released (Iterative).

Mirror X method mirrors free hand drawing verticaly, i.e. X point is repeated as -X. Y value is the same as original drawing.

You can specify point of symmetry by selecting image center (mirroring is perforemd around image center: Xc,Yc) or starting point (mirroring is performed around starting point of drawing).

Drawing shape (free hand, jitter hand) can be selected by right mouse click.

Mirror Y method is similar to above method, but in this case X values are the same and Y point of drawing is repeated as -Y.

Mirror XY method is actualy
Mirror Y( Mirror X) composition. X is repeated as -X and then both drawings are repeated with -Y which gives four symmetrical patterns.

Polar 180 performs polar symmetry drawing by rotating original drawing for 180 degrees. Two symmetrical patterns are created.

Polar 120 performs polar symmetry drawing by rotating original drawing for 120 degrees and agian for 120 degrees (2 * 120). Three symmetrical patterns are created.

Polar 90 performs polar symmetry drawing by rotating original drawing for 90 degrees (3 * 90). Four symmetrical patterns are created.

Polar 72 performs polar symmetry drawing by rotating original drawing for 72 degrees (4 * 72). Five symmetrical patterns are created.

Polar 60 performs polar symmetry drawing by rotating original drawing for 60 degrees (5 * 60). Six symmetrical patterns are created.

Tree method is iterative drawing method and draws a binary tree of given depth. After drawing some pattern, when mouse button is released, iterations are performed, i.e. drawing is repeated: original pattern is shrinked by length decrease percentage (if checked), starting point is shifted to pattern edning point and rotated by angle creating one branch, and than rotated by -angle giveing second branch. Whole process is repeated until depth is reached.

If size decrease is checked, brush size is also decreased. If capacity decrease is checked, brush capacity is also decreased by given percentage specified in decr % edit field.

Bush method is similar to tree method, but now, pattern is repeated not only from ending but also from starting point.

Closer method repeats original drawing by rotating it for an -angle in such way that original ending point is new starting point for repeated pattern. The number of patterns drawn is:
Num_draw = round(360/angle). If 360 is divisible by angle, i.e. 360%angle = 0, last patter ending point is exactly original pattern starting point, so the pattern is closed.

Closer method is very similar to polar symmetry, but you can specify arbitrary symmetry angle. Original drawing is rotated around starting point for an -angle and repeated 360/angle times.
