IESoftShadowSize


Declaration

function IESoftShadowSize(Radius: Double; OffSetX: Integer; OffSetY: Integer) : Integer;


Description

If you call AddSoftShadow with AdaptSize enabled then the dimensions of your image will be enlarged so the content does not change to fit the shadow.

This function returns the number of pixels that will be added in height and width by calling AddSoftShadow.

Note: Regardless of your values for OffSetX/OffSetY AddSoftShadow always increases the width and height by the same value


Example

Var
  iSoftShadowSize: Integer;
Begin
  iSoftShadowSize := IESoftShadowSize(ImageEnView1.Proc.SoftShadow.Radius, ImageEnView1.Proc.SoftShadow.OffsetX, ImageEnView1.Proc.SoftShadow.OffsetY);
  ShowMessage(Format('Adding a soft shadow will enlarge the image to %d x %d',
                     [ImageEnView1.IEBitmap.Width + iShadowSize,
                      ImageEnView1.IEBitmap.Height + iShadowSize]);
End;
