xform:AffineTransform: device scale transform

Exceptions

IOException:: if something goes wrong while drawing the pattern

Method Detail

ceiling	back to summary
private static int ceiling(double num) Returns the closest integer which is larger than the given number. Uses BigDecimal to avoid floating point error which would cause gaps in the tiling.
