    How to check the rotated spreads?

    seuzo-oJiFme Level 1

      Hi all,

       

      Mac OS X 10.5.6/InDesign 6.01/JavaScript or AppleScript

       

      When the spreads is rotated view, the page item's visibleBounds (and geometricBounds) is change.

      How to method of examining whether the spreads rotated?

      example:

       

      my_spread = app.layoutWindows[0].activeSpread;

      my_spread.rotate; //of course, error

      //I wish like this , =>ROTATE_CCW Value: 1987736183

       

       

      Thanks.

          I do not see a property that directly provides this information.

           

          You can work out whether or not a spread is rotated by looking at the page.bounds, but that seems a rather clumsy way to get the information.

            You can work out whether or not a spread is rotated by looking at

            the page.bounds,

             

            Oh, no!!!

             

            I never realized that bounds were effected by page rotation. That's

            bad, bad, bad!!!

             

            This will mess up just about every script under the sun which deals

            with bounds of any kind!

             

            We  need this changed...

             

            It is just a rotated view after all, so why are the bounds effected?

              It's probably something to do with spread.transformValuesOf (myCoordinateSpace), but I never really got my brain round transformation matrices. They're fiendishly complicated! In the old forums there was a sticky topic by Ole on transf. matrices, but I don't see that now.

                Agreed. Goes for the whole transformation business.

                 

                > It is just a rotated view after all, so why are the bounds effected?

                 

                I guess that though it's a view, the spreads are really rotated. At print time they're probably rotated back.

                  Thank you!

                   

                  This is good method for only check.

                  I can stop myscript, if the spreads is rotate.

                   

                   

                  function spread_angle(page_obj) {

                       //The bounds of the Page, in the format [y1, x1, y2, x2].

                       var my_page_bounds = page_obj.bounds;

                       var y1 = my_page_bounds[0];

                       var x1 = my_page_bounds[1];

                       var y2 = my_page_bounds[2];

                       var x2 = my_page_bounds[3];

                   

                       if((y1 == 0) && (x1 == 0)) {

                            return 0;

                       } else if ((y1 == 0) && (x2 == 0)) {

                            return 90;

                       } else if ((y2 == 0) && (x2 == 0)) {

                            return 180;

                       } else if ((x1 == 0) && (y2 == 0)) {

                            return 270;

                       }

                  }

                  var my_page = app.layoutWindows[0].activePage;

                  spread_angle(my_page);

                   

                  >We  need this changed...

                   

                  I agreed too...

                   

                  Again, thanks.

                    Just make sure the zeroPoint is set to , and the rulerOrigin is 

                    page. I like to work with spread origin, in which case, you'd pass a 

                    spread instead of a page...

                      I agree that this is indeed bad, bad, bad.

                       

                      If the coordinates are changed by this action then I would expect at least a spread property that tells you the spread is rotated.

                        Oops!

                        I had overlooked some matters. It is as you say.

                          Hi Seuzo,

                           

                          Very well done.

                           

                          I took your code and cleaned it up the way I would have done it (I don't think you gain very much -- if anything, from all those "if"s). I also restructured the function to accept both Page and Spread objects. Assuming that the document is the active one is not a safe asumption. I changed that as well...

                           

                          function GetSpreadRotation(pageOrSpread) {//accepts a Page, Spread, or MasterSpread
                            var doc = pageOrSpread.parent;// the doc will be either the parent, or the parent's parent...
                            if(pageOrSpread instanceof Page){doc=doc.parent}
                            //if(!(doc instanceof Document)){return null}// uncomment this to error check for the wrong type of pageOrSpread...
                            var origRulerOrigin = doc.viewPreferences.rulerOrigin;
                            var origZP = doc.zeroPoint;
                            doc.zeroPoint=[0,0];
                            doc.viewPreferences.rulerOrigin = RulerOrigin.PAGE_ORIGIN;
                            var page = pageOrSpread;
                            if (!(page instanceof Page)){// it must be a Spread or MasterSpread
                              page=pageOrSpread.pages[0];
                            }
                            var pageBounds = page.bounds;
                            var retAngle = 0;
                            if(pageBounds[0] == 0 && pageBounds[1] == 0) {
                              retAngle = 0;
                            } else if (pageBounds[0] == 0 && pageBounds[3] == 0) {
                              retAngle = 90;
                            } else if (pageBounds[2] == 0 && pageBounds[3] == 0) {
                              retAngle = 180;
                            } else if (pageBounds[1] == 0 && pageBounds[2] == 0) {
                              retAngle = 270;
                            }
                            doc.viewPreferences.rulerOrigin = origRulerOrigin;
                            doc.zeroPoint = origZP;
                            return retAngle;
                          }
                          var doc=app.documents[0];
                          var spread = doc.spreads[0];
                          spread_angle = GetSpreadRotation(spread);
                          alert("Spread Angle: " + spread_angle);
                          var page = doc.pages[0];
                          spread_angle = GetSpreadRotation(page);
                          alert("Page Angle: " + spread_angle);
                          var masterSpread = doc.masterSpreads[0];

                            Thank you for rewriting my code.

                            I see, the object passed to the function might not be activeDocumetnt's.
