Signals

void invalidateThumbnail (PageId const &page_id)

Public Member Functions

void adjustAndSetWidgetFocalPoint (QPointF const &widget_fp)
 Set the focal point in widget coordinates, after adjustring it to avoid wasting of widget space.
QPixmap const & downscaledPixmap () const
void ensureStatusTip (QString const &status_tip)
 A better version of setStatusTip().
QRectF getOccupiedWidgetRect () const
QPointF getWidgetFocalPoint () const
 Get the focal point in widget coordinates.
void hqTransformSetEnabled (bool enabled)
 Enable or disable the high-quality transform.
QTransform const & imageToVirtual () const
QTransform imageToWidget () const
InteractionStateinteractionState ()
InteractionState const & interactionState () const
void moveTowardsIdealPosition (double pixel_length)
 PictureZoneEditor (QImage const &image, ImagePixmapUnion const &downscaled_image, imageproc::BinaryImage const &picture_mask, QTransform const &image_to_virt, QPolygonF const &virt_display_area, PageId const &page_id, IntrusivePtr< Settings > const &settings)
InteractionHandlerrootInteractionHandler ()
void setWidgetFocalPoint (QPointF const &widget_fp)
 Set the focal point in widget coordinates.
void setWidgetFocalPointWithoutMoving (QPointF new_widget_fp)
 Sets the widget focal point and recalculates the pixmap focal focal point so that the image is not moved on screen.
void setZoomLevel (double zoom)
 Sets the zoom level.
void update ()
void updateTransform (ImagePresentation const &presentation)
 Updates image-to-virtual and recalculates virtual-to-widget transformations.
void updateTransformAndFixFocalPoint (ImagePresentation const &presentation, FocalPointMode mode)
 Same as updateTransform(), but adjusts the focal point to improve screen space usage.
void updateTransformPreservingScale (ImagePresentation const &presentation)
 Same as updateTransform(), but preserves the visual image scale.
QRectF const & virtualDisplayRect () const
QTransform const & virtualToImage () const
QTransform const & virtualToWidget () const
QTransform widgetToImage () const
QTransform const & widgetToVirtual () const
double zoomLevel () const
 Returns the current zoom level.

Static Public Member Functions

static BackgroundExecutorbackgroundExecutor ()
static QImage createDownscaledImage (QImage const &image)
