public class IltPatternFunction extends IlvCSSFunction
IltPattern
based on user input.
This class can generate the following types of patterns:
Grid SkewGrid Dots ThinHatchingRefer to
IltPattern
for more details
about these patterns.
It can also generate patterns corresponding to an
IlvPattern
.
Refer to
for a list
of available patterns.
The function is defined as follows:
IlvPattern
aPattern : '@|pattern("Grid", 3, 2)';
bPattern : '@|pattern("SkewGrid", 2, 2)';
cPattern : '@|pattern("Dots")';
dPattern : '@|pattern("ThinHatching")';
ePattern : '@|pattern("LIGHT_VERTICAL")';
The Grid
is a pattern parallel to the x-axis and the y-axis.
It gets two integer arguments:
xPeriod
. It is the horizontal distance between two
dots. Use 1 (one) for a continuous horizontal hatching.
yPeriod
. It is the vertical distance between two
dots. Use 1 (one) for a continuous vertical hatching.
The SkewGrid
is a pattern parallel to the diagonals, that is,
the bisectors between the x-axis and y-axis. It gets two integer arguments:
uPeriod
. The pattern is translation invariant with
respect to the vector (uPeriod/2,uPeriod/2). Use 2 (two) for a
continuous diagonal hatching.
vPeriod
. The pattern is translation invariant with
respect to the vector (vPeriod/2,-vPeriod/2). Use 2 (two) for a
continuous anti-diagonal hatching.
IlvPattern.GRAY_20
.
ThinHatching
is a skew grid pattern that provides fine
hatching. It is equivalent to
IlvPattern.UP_DIAGONAL
.
LIGHT_VERTICAL
is one of the pattern types defined in
IlvPattern
and it is used as an example. Any of the patterns
available in that class can be used. See
IlvPattern
for more details.
