Change halftone origin.

This Enfocus PitStop command allows us to set the value of the origin point of halftones. If nothing is selected, the action will affect all halftones within its range.

Taking into account the coordinates system in PostScript and PDF format, we can set the horizontal ("X") and vertical ("Y") values of this point in two possible planes. In both cases, positive and negative values are allowed:

  • HTO on page: The bottom left corner of each page is used as the origin, which defaults to the value ("0.0") and then has the user-supplied values subsequently added.
  • HTO in form: In this case, the lower left corner of the largest XForm Object that encompasses the other selected forms is used as the origin value ("0.0").
