draw()

void ImageSlide::draw ( SkCanvas *  canvas )

overridevirtual

Implements Slide.

getDimensions()

SkISize ImageSlide::getDimensions ( ) const

overridevirtual

A slide may have a content dimensions that is independent of the current window size. An empty size indicates that the Slide's dimensions are equal to the window's dimensions.

Reimplemented from Slide.

}

load()

void ImageSlide::load ( SkScalar  winWidth, SkScalar  winHeight  )

overridevirtual
