I use the following code to automatically locate the object into view. This works perfect if the object is not rotated. Once I have performed a RotateAllObjects,the code does not seem to show the object correctly. How do I modify the code to handle rotated objects?

l := ImageEnVect1.ObjLeft[0];
t := ImageEnVect1.ObjTop[0];

xx:=trunc( l * (ImageEnVect1.Zoom/100) );
yy:=trunc( t * (ImageEnVect1.Zoom/100) );
ImageEnVect1.SetViewXYSmooth( xx-5, yy-5 );

Thanks in advance.

Andy

Thanks again.

Hi Andy

TImageEnVect allows for ObjLeft > ObjRight and ObjTop > ObjBottom to handle line drawing (know which way the line is pointing (TR->BL or TL->BR).

So please change your code as follows:

ImageEnVect1.GetObjRect( 0, aRect );
l := imin( aRect.Left, aRect.Right ) ;
t := imin( aRect.Top, aRect.Bottom ) ;

xx:=trunc( l * ( ImageEnVect1.Zoom / 100 ));
yy:=trunc( t * ( ImageEnVect1.Zoom / 100 ));
ImageEnVect1.SetViewXYSmooth( xx - 5, yy - 5 );

Hi Andy

There is a limitation here due to the way returns object positions. We are investigating a solution.
