    applyImpl(painter, rect, thresholdMode);
}

References applyImpl().

changeRect()

QRect KisLayerProjectionPlane::changeRect ( const QRect & rect, KisLayer::PositionToFilthy pos ) const

overridevirtual

Works like KisNode::changeRect(), but includes more transformations of the layer

Implements KisAbstractProjectionPlane.

Definition at line 97 of file kis_layer_projection_plane.cpp.

{
    return m_d->layer->changeRect(rect, pos);
}

getLodCapableDevices()

KisPaintDeviceList KisLayerProjectionPlane::getLodCapableDevices ( ) const

overridevirtual

Returns a list of devices which should synchronize the lod cache on update

Implements KisAbstractProjectionPlane.

Definition at line 87 of file kis_layer_projection_plane.cpp.

{
    return KisPaintDeviceList() << m_d->layer->projection();
}

References m_d.

looseUserVisibleBounds()

QRect KisLayerProjectionPlane::looseUserVisibleBounds ( ) const

overridevirtual

Return an approximate (loose) rectangle, where the contents of the plane is placed from user's point of view. It includes everything belonging to the plane (e.g. layer styles).

This rectangle contains or is bigger than the rectangle returned by tightUserVisibleBounds().

Implements KisAbstractProjectionPlane.

Definition at line 117 of file kis_layer_projection_plane.cpp.

{
    return m_d->layer->looseUserVisibleBounds();
}

References m_d.

needRect()

QRect KisLayerProjectionPlane::needRect ( const QRect & rect, KisLayer::PositionToFilthy pos ) const

overridevirtual

Works like KisNode::needRect(), but includes more transformations of the layer

Implements KisAbstractProjectionPlane.

Definition at line 92 of file kis_layer_projection_plane.cpp.

{
    return m_d->layer->needRect(rect, pos);
}

References m_d.

needRectForOriginal()

QRect KisLayerProjectionPlane::needRectForOriginal ( const QRect & rect ) const

overridevirtual

Works like KisLayer::needRectForOriginal(), but includes needed rects of layer styles

    return m_d->layer->needRectForOriginal(rect);
}

References m_d.

recalculate()

QRect KisLayerProjectionPlane::recalculate ( const QRect & rect, KisNodeSP filthyNode, KisRenderPassFlags flags )

overridevirtual

Is called by the async merger when the node is filthy and should recalculate its internal representation. For usual layers it means just calling updateProjection().

Implements KisAbstractProjectionPlane.

Definition at line 36 of file kis_layer_projection_plane.cpp.

{
    return m_d->layer->updateProjection(rect, filthyNode, flags);
}

References m_d.

tightUserVisibleBounds()

QRect KisLayerProjectionPlane::tightUserVisibleBounds ( ) const

overridevirtual

Return a tight rectangle, where the contents of the plane is placed from user's point of view. It includes everything belonging to the plane (e.g. layer styles).

Implements KisAbstractProjectionPlane.

Definition at line 112 of file kis_layer_projection_plane.cpp.
