### Description

A plot function for quadtree decompositions.

### Usage

### Arguments

`x` |
A quadtree decomposition object, such as output from |

`cires` |
Results of |

`unclassval` |
A value for unclassified values in a quadtree decomposition. |

`class` |
A boolean value indicating whether to plot the results from |

`QT` |
A boolean value indicating whether to plot the quadtree decomposition. |

`return` |
A boolean value indicating whether to return the matrix associated to the plotted image. |

`qtl` |

`...` |
Any other optional arguments to |

### Details

The function plots the chosen quadtree decomposition, and optionally the textured region classification output from `countTextures`

. If the classification output is plotted (`class=TRUE`

), each textured region is uniquely coloured according to its texture group.

### Value

`immat` |
the matrix associated to the plotted image. |
