negative input points #10

Closed ghost closed 4 years ago

ghost commented 4 years ago

@chris1010010 At times, the input Alto file might contain negative input points like this ="-90 in that case, the converter fails.

Solution, add an option to deal with the negative points.

Hi, which option would be most useful in your case? Remove objects with negative coordinates? Try to cut off at 0? PAGE forbids negative coordinates, so some form of correction is needed.

hmmmmm.... can you for now,

skip any region that contains a negative point While I speak with kermitt to fix the negative issue from pdfalto

chris1010010 commented 4 years ago

Added -neg-coords command line option with two modes: removeObj (skip object with negative point(s)), toZero (change negative values to zero)
