Detailed Description

2D (xy) grid renderer.

Draws x and y gridlines for the specified image.

Constructor & Destructor Documentation

ome::qtwidgets::gl::v20::Grid2D::Grid2D ( ome::compat::shared_ptr< ome::bioformats::FormatReader >  reader, ome::bioformats::dimension_size_type  series, QObject *  parent = 0  )

explicit

Create a 2D grid.

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.

Member Function Documentation

void ome::qtwidgets::gl::v20::Grid2D::render ( const glm::mat4 &  mvp, float  zoom  )

virtual

Render the grid.

The zoom level is used to selectively draw gridlines of differing magnitude depending upon the magnification.

Parameters

mvp	the model view projection matrix.
zoom	the zoom level.

Implements ome::qtwidgets::gl::Grid2D.
