Subject: 'calspair' unit type
I'm working on a stylesheet enhancement to add support for <imageobjectco> using the 'calspair' unit type to the DocBook XSL stylesheets, and I have a question involving the proper interpration of this unit type. The Def. Guide reads: "The coordinates are expressed using the semantics of the CALS graphic attributes. The format of the coordinates is "x1,y1 x2,y2". This identifies a rectangle with the lower-left corner at (x1,y1) and the upper-right corner at (x2,y2). The X and Y coordinates are integers in the range 0 to 10000; they express a percentage of the total distance from 0.00 to 100.00%." My question is, where is the point (0,0)? I started out by calculating everything from the top-left corner, but further consideration got me to wondering if the bottom-left corner was correct. Jeff Beal Tools Specialist ANSYS, Inc.
