## Detailed Description

An Ipe document page.

Its main ingredients are a sequence of Objects (with selection state, layer, and a cached bounding box), a set of Layers, and a sequence of Views.

Each object on a Page belongs to one of the layers of the page. Layers are orthogonal to the back-to-front ordering of objects (in particular, they are not "layered" - the word is a misnomer). The "layer" is really just another attribute of the object.

- Layers are either editable or locked. Objects in a locked layer cannot be selected, and a locked layer cannot be made active in the UI. This more or less means that the contents of such a layer cannot be modified—but that's a consequence of the UI, Ipelib contains no special handling of locked layers.
- A layer may have snapping on or off—objects will behave magnetically only if their layer has snapping on.

A Page is presented in a number of views. Each view presents some of the layers of the page. In addition, each view has an active layer (where objects are added when this view is shown in the UI), and possibly a transition effect (Acrobat Reader eye candy).

A Page can be copied and assigned. The operation takes time linear in the number of top-level object on the page.

## ◆ pageBBox()

Rect Page::pageBBox | ( | const Cascade * | sheet | ) | const

Returns a precise bounding box for the artwork on the page.

This is meant to be used as the bounding box in PDF output. It is computed by rendering all objects on the page that are visible in at least one view, plus all objects in a layer named "BBOX" (even if that is not visible), using a BBoxPainter.

References ipe::BBoxPainter::bbox(), count(), countLayers(), countViews(), layer(), layerOf(), and visible().

Referenced by ipe::PdfWriter::createPageView(), ipe::Thumbnail::saveRender(), and setLayerOf().

## ◆ viewBBox()

Rect Page::viewBBox | ( | const Cascade * | sheet,
|  | int | view
| ) |  | const

Returns a precise bounding box for the artwork in the view.

This is meant to be used as the bounding box in PDF and EPS output. It is computed by rendering all objects in the page using a BBoxPainter.

References ipe::BBoxPainter::bbox(), count(), and objectVisible().

Referenced by ipe::PdfWriter::createPageView(), and setLayerOf().

## ◆ bbox()

Rect Page::bbox | ( | int | i | ) | const

Return a bounding box for the object at index i.

This is a bounding box including the control points of the object. If you need a tight bounding box, you'll need to use the Object directly.

The Page caches the box the first time it is computed.

Make sure you call Page::transform instead of Object::setMatrix, as the latter would not invalidate the bounding box.

Referenced by ipe::PdfWriter::createPageView(), distance(), setLayerOf(), snapBnd(), snapCtl(), snapVtx(), and ipe::TransformTool::TransformTool().

## ◆ transform()

void Page::transform | ( | int | i,
|  | const Matrix & | m
| ) |  |

Transform the object at index i.

Use this function instead of calling Object::setMatrix directly, as the latter doesn't invalidate the cached bounding box.

References invalidateBBox(), object(), and ipe::Object::setMatrix().

Referenced by setLayerOf().

## ◆ distance()

double Page::distance | ( | int | i,
|  | const Vector & | v,
|  | double | bound
| ) |  | const

Return distance between object at index i and v.

But may just return bound if the distance is larger. This function uses the cached bounded box, and is faster than calling Object::distance directly.

References bbox(), ipe::Object::distance(), and object().

Referenced by ipe::SelectTool::SelectTool(), and setLayerOf().

## ◆ snapVtx()

void Page::snapVtx | ( | int | i,
|  | const Vector & | mouse,
|  | Vector & | pos,
|  | double & | bound
| ) |  | const

Compute possible vertex snapping position for object at index i.

Looks only for positions closer than bound. If successful, modifies pos and bound.

References bbox(), object(), and ipe::Object::snapVtx().

Referenced by setLayerOf(), and ipe::Snap::simpleSnap().

## ◆ snapCtl()

void Page::snapCtl | ( | int | i,
|  | const Vector & | mouse,
|  | Vector & | pos,
|  | double & | bound
| ) |  | const

Compute possible control point snapping position for object at index i.

Looks only for positions closer than bound. If successful, modifies pos and bound.

Referenced by setLayerOf(), and ipe::Snap::simpleSnap().

## ◆ snapBnd()

void Page::snapBnd | ( | int | i,
|  | const Vector & | mouse,
|  | Vector & | pos,
|  | double & | bound
| ) |  | const

Compute possible boundary snapping position for object at index i.

Looks only for positions closer than bound. If successful, modifies pos and bound.

References bbox(), object(), and ipe::Object::snapBnd().

Referenced by setLayerOf(), and ipe::Snap::simpleSnap().

## ◆ invalidateBBox()

void Page::invalidateBBox | ( | int | i | ) | const

Invalidate the bounding box at index i (the object is somehow changed).

Referenced by replace(), ipe::Latex::scanPage(), setAttribute(), setLayerOf(), and transform().

## ◆ insert()

void Page::insert | ( | int | i,
|  | TSelect | select,
|  | int | layer,
|  | Object * | obj
| ) |  |

Insert a new object at index i.

Takes ownership of the object.

References layer(), and select().

Referenced by ipe::ImlParser::parsePage(), and setLayerOf().

## ◆ append()

void Page::append | ( | TSelect | select,
|  | int | layer,
|  | Object * | obj

Append a new object.

Takes ownership of the object.

References layer(), and select().

## ◆ setAttribute()

bool Page::setAttribute | ( | int | i,
|  | Property | prop,
|  | Attribute | value
| ) |  |

Set attribute prop of object at index i to value.

This method automatically invalidates the bounding box if a ETextSize property is actually changed.

Referenced by setLayerOf().

## ◆ primarySelection()

int Page::primarySelection | ( |  | ) | const
