Detailed Description

class for drawing the outlines of the preview canvas and the crop rectangle in the overview openl scenes it also creates meshes that are used to darken the outside regions it works similarly to the mesh remapper used for the images, with the exception that instead of remapping from image to projection, this needs to remap from projection to another projection

it has two modes of operation:

• Subdivide the mesh recursively until a mesh with desired resolution is obtained.
  • This is very good in most of the cases except where the canvas also covers some regions not in the panorama
  • This corresponds to the vertex coord remapper
• Subdivide the mesh certain amount of times in all directions
  • This corresponds to the tex coord remapper

panoramaChanged()

void OverviewOutlinesTool::panoramaChanged ( HuginBase::Panorama &  pano )

virtual

Notification about a Panorama change.

This function will always be called, even when the change could be handled by panoramaImageAdded() or other notify functions.

This allows lazy observers to just listen to panoramaChanged().

Implements HuginBase::PanoramaObserver.

panoramaImagesChanged()

virtual void OverviewOutlinesTool::panoramaImagesChanged ( HuginBase::Panorama &  pano, const HuginBase::UIntSet &  changed  )

inlinevirtual

notifies about changes to images

Images might have been added/removed. to find out how many images are still there, use Panorama::getNrOfImages.

Parameters

pano	the panorama object that changed
changed	set of changed images

Implements HuginBase::PanoramaObserver.
