Detailed Description

2D (xy) grid renderer.

Draws x and y gridlines for the specified image.

Constructor & Destructor Documentation

ome::qtwidgets::gl::Grid2D::Grid2D ( ome::compat::shared_ptr< ome::files::FormatReader >  reader, ome::files::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::Grid2D::create ( )

virtual

Create GL buffers.

Note

Requires a valid GL context. Must be called before rendering.

Referenced by ome::qtwidgets::GLView2D::initialize().

Here is the caller graph for this function:

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

pure 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.

Implemented in ome::qtwidgets::gl::v20::Grid2D.

Referenced by ome::qtwidgets::GLView2D::render().

Here is the caller graph for this function:

void ome::qtwidgets::gl::Grid2D::setSize ( const glm::vec2 &  xlim, const glm::vec2 &  ylim  )

protectedvirtual

Set the size of the x and y axes.

Parameters

xlim	the x axis limits (range).
ylim	the y axis limits (range).
