TIELayer.AspectRatioLocked

Declaration

property AspectRatioLocked: Boolean;

Description

When enabled the PreferredAspectRatio for the layer will be enforced regardless of the setting for LayersResizeAspectRatio.

Note:
◼You may want to call RestoreAspectRatio before enabling AspectRatioLocked if you want to lock to the best AR for this layer
◼Dragging grips other than the corner will still allow users to skew the image. To avoid this use ShiftKeyLock
◼For polyline and shape layers, you can also maintain the aspect ratio when rotating by adding loResizeOnRotate to LayerOptions
◼AspectRatioLocked has no effect with line layers

Default: False (Except for TIEAngleLayer, where default is true)

Examples

// Lock layer to the current aspect ratio
ImageEnView1.CurrentLayer.AspectRatioLocked := True;

// Force aspect ratio locking if the object prefers it
if ImageEnView1.CurrentLayer.PreferredAspectRatio <> 0 then
begin
  ImageEnView1.CurrentLayer.RestoreAspectRatio( True);
  ImageEnView1.CurrentLayer.AspectRatioLocked := True;
  ImageEnView1.Update();
end;


// Add a "Shape" layer with vertically offset text
ImageEnView1.LayersAdd( ielkText, 200, 200, 230, 200 );
ImageEnView1.CurrentLayer.AspectRatioLocked            := True;
