Hi All,
I want to do group rotation for various objects. Objects are getting rotate
correctly on their center but when I group them the rotated object has got
shift. Note: In case of group only rotated object has got shift. Below is
the code snippet. Let me know I doing correct or not.
-(NSRect)drawingBoundForGroup:(int)in_Group
{
NSRect rect = NSZeroRect;
NSArray *objTlGraphic = [[self document] graphics];
unsigned i,c = [objTlGraphic count];
if(in_Group != 0)
{
for(i = 0; i < c;i++)
{
if([[objTlGraphic objectAtIndex:i] GroupNO]==in_Group)
{
rect=NSUnionRect(rect,[[objTlGraphic objectAtIndex:i] bounds]);
NSLog(@"Object Center Log Index= %d %d",rect,i);
}
}
}
return rect;
}
int Id_Group=[curGraphic GroupNO];
NSRect stRect=[curGraphic drawingBoundForGroup:Id_Group];
NSAffineTransform* xform = [NSAffineTransform transform];
[currentContext saveGraphicsState];
[NSBezierPath clipRect:drawingBounds];
NSPoint center = NSMakePoint(NSMidX(stRect), NSMidY(stRect));
[xform translateXBy:center.x yBy:center.y];
[xform rotateByDegrees:[curGraphic GetAngle]];
[xform translateXBy:-center.x yBy:-center.y];
[xform concat];
[curGraphic drawInView:self isSelected:isSelected];
[currentContext restoreGraphicsState];
[self setNeedsDisplay:YES];
Thanks in advance,
