Detailed Description

2D (xy) axis renderer.

Draws x and y axes for the specified image.

Constructor & Destructor Documentation

ome::qtwidgets::gl::Axis2D::Axis2D ( ome::compat::shared_ptr< ome::files::FormatReader >  reader, ome::files::dimension_size_type  series, QObject *  parent = 0  )

explicit

Create a 2D axis.

The size and position will be taken from the specified image.

Parameters

reader	the image reader.
series	the image series.
parent	the parent of this object.
