Detailed Description

A scaled image plane pulls data from a RawImagePlane and resizes it.

Member Function Documentation

ensureUpToDate()

void khtmlImLoad::ScaledImagePlane::ensureUpToDate ( unsigned int  tileX, unsigned int  tileY, PixmapTile *  tile  )

overridevirtual

Ensures that the given pixmap tile is up-to-date.

Implements khtmlImLoad::ImagePlane.

Definition at line 101 of file scaledimageplane.cpp.

isUpToDate()

bool khtmlImLoad::ScaledImagePlane::isUpToDate ( unsigned int  tileX, unsigned int  tileY, PixmapTile *  tile  )

overridevirtual

Returns true if the given pixmap tile is up-to-date.

Note that this should compare the information in the pixmap with ideal the up-to-date image using the decoding information thus far, and not with the state of the image proper. (Which might not even be in memory)

Implements khtmlImLoad::ImagePlane.
