Constructor & Destructor Documentation

◆ PixmapRequest()

PixmapRequest::PixmapRequest ( DocumentObserver * observer,
int pageNumber,
int width,
int height,
qreal dpr,
int priority,
PixmapRequestFeatures features )

Creates a new pixmap request.

Parameters
observerThe observer.
pageNumberThe page number.
widthThe width of the page in logical pixels.
heightThe height of the page in logical pixels.
dprDevice pixel ratio of the screen that the pixmap is intended for.
priorityThe priority of the request.
featuresThe features of generation.

Definition at line 581 of file generator.cpp.

◆ ~PixmapRequest()

PixmapRequest::~PixmapRequest ( )

Destroys the pixmap request.

Definition at line 597 of file generator.cpp.

Member Function Documentation

◆ asynchronous()

bool PixmapRequest::asynchronous ( ) const

Returns whether the generation should be done synchronous or asynchronous.

If asynchronous, the pixmap is created in a thread and the observer is notified when the job is done.

Definition at line 627 of file generator.cpp.

◆ height()

int PixmapRequest::height ( ) const

Returns the page height of the requested pixmap.

Definition at line 617 of file generator.cpp.

◆ isTile()

bool PixmapRequest::isTile ( ) const

Returns whether the generator should render just the region given by normalizedRect() or the entire page.

Since
0.16 (KDE 4.10)

Definition at line 647 of file generator.cpp.

◆ normalizedRect()

const NormalizedRect & PixmapRequest::normalizedRect ( ) const

Returns the normalized region of the page to request.

Since
0.16 (KDE 4.10)

Definition at line 661 of file generator.cpp.

◆ observer()

DocumentObserver * PixmapRequest::observer ( ) const

Returns the observer of the request.

Definition at line 602 of file generator.cpp.

◆ page()

Page * PixmapRequest::page ( ) const

Returns a pointer to the page where the pixmap shall be generated for.

Definition at line 637 of file generator.cpp.

◆ pageNumber()

int PixmapRequest::pageNumber ( ) const

Returns the page number of the request.

Definition at line 607 of file generator.cpp.

◆ partialUpdatesWanted()

bool PixmapRequest::partialUpdatesWanted ( ) const

Should the request report back updates if possible?

Since
1.3

Definition at line 671 of file generator.cpp.

◆ preload()

bool PixmapRequest::preload ( ) const

Returns whether the generation request is for a page that is not important i.e.

it's just for speeding up future rendering

Definition at line 632 of file generator.cpp.

◆ priority()

int PixmapRequest::priority ( ) const

Returns the priority (less it better, 0 is maximum) of the request.

Definition at line 622 of file generator.cpp.

◆ setNormalizedRect()

void PixmapRequest::setNormalizedRect ( const NormalizedRect & rect)

Sets the region of the page to request.

Since
0.16 (KDE 4.10)

Definition at line 652 of file generator.cpp.

◆ setPartialUpdatesWanted()

void PixmapRequest::setPartialUpdatesWanted ( bool partialUpdatesWanted)

Sets whether the request should report back updates if possible.

Since
1.3

Definition at line 666 of file generator.cpp.

◆ setTile()

void PixmapRequest::setTile ( bool tile)

Sets whether the generator should render only the given normalized rect or the entire page.

Since
0.16 (KDE 4.10)

Definition at line 642 of file generator.cpp.

◆ shouldAbortRender()

bool PixmapRequest::shouldAbortRender ( ) const

Should the request be aborted if possible?

Since
1.4

Definition at line 676 of file generator.cpp.

◆ width()

int PixmapRequest::width ( ) const

Returns the page width of the requested pixmap.

Definition at line 612 of file generator.cpp.
