Field Detail

MAX_DELTA_IN_TWIPS

public static final int MAX_DELTA_IN_TWIPS

The maximum value that an EdgeRecord delta can take in SWF.

This limit arises due to the SWF encoding format of a Shape's EdgeRecord. A delta is encoded using a specified bit length, however, the number of bits used to record this bitlength (minus 2) is restricted to 4 bits, which is 15 + 2 = 17 bits for unsigned, or 16 bits for signed.

This restricts the signed delta values to 65535 twips, i.e. (2 pow 16) - 1.
