Class SKImagePyramidTileLayout

Namespace

SkiaSharp.Extended

Assembly

SkiaSharp.Extended.dll

Computes tile geometry for the ImagePyramid pipeline: which tiles are visible, what fallback tiles exist, and where tiles should be drawn on screen. Works with any ISKImagePyramidSource including DZI and IIIF sources.

Methods

FindBestFallback(SKImagePyramidTileId, ISKImagePyramidTileCache, int)

For a missing tile, finds the best available parent tile as a fallback. Walks up the pyramid from the requested level until a cached tile is found.

GetFallbackSourceRect(SKImagePyramidTileId, SKImagePyramidTileId, ISKImagePyramidSource)

Computes the source rect within a parent tile that corresponds to the child tile. Returns an SKRect in parent-bitmap pixel coordinates.

GetTileDestRect(ISKImagePyramidSource, SKImagePyramidViewport, SKImagePyramidTileId)

Computes the screen-space destination rect for a tile given the current viewport. Previously on SKImagePyramidRenderer; moved here because it is pure geometry, independent of any rendering backend.

GetVisibleTiles(ISKImagePyramidSource, SKImagePyramidViewport)

Computes the set of tiles visible in the current viewport at the optimal level.
