Mirroring the image function

Other specific code bases look ahead: http://blog.csdn.net/cutter_point/article/details/42839071

Slot function:

  void Showmirrorvertical ();    Vertical mirror  void showmirrorhorizontal ();    Horizontal mirroring

The corresponding response connection

  Implementation of image Mirroring action  //portrait  mirrorverticalaction = new Qaction (Qicon ("Mirrorvertical.png"), tr ("Mirrorvertical"), this );  Mirrorverticalaction->setstatustip (TR ("mirrorvertical the Image");  Connect (mirrorverticalaction, SIGNAL (triggered ()), this, SLOT (Showmirrorvertical ()));  Transverse  mirrorhorizontalaction = new Qaction (Qicon ("Mirrorhorizontal.png"), tr ("Mirrorhorizontal"), this);  Mirrorhorizontalaction->setstatustip (TR ("Mirrorhorizontal the Image");  Connect (mirrorhorizontalaction, SIGNAL (triggered ()), this, SLOT (Showmirrorhorizontal ()));

The implementation of the slot function:

Horizontal mirror void imageprocessor::showmirrorvertical () {  if (Img.isnull ())    return;  img = Img.mirrored (true, false);    Horizontal mirroring  Showwidget->imagelabel->setpixmap (Qpixmap::fromimage (IMG));} Vertical mirror void imageprocessor::showmirrorvertical () {  if (Img.isnull ())    return;  img = img.mirrored (false, true);    Vertical Mirror  showwidget->imagelabel->setpixmap (Qpixmap::fromimage (IMG));}

Operation Result:

Well, do not know what happened, the picture can not get up, then save it, anyway is vertical is upside down, horizontal is the effect of horizontal transverse shift!!! ，
