Public functions

void setPatch(int level, int x, int y, std::shared_ptr<Image> patch, bool propagate = true)

Write a patch to the pyramid.

void setBlankPatch(int level, int x, int y)

Write patch/tile as empty. It will render as white/black.

auto isPatchInitialized(int level, int x, int y) -> bool

template<class T>

auto getPatchData(int level, int x, int y, int width, int height) -> std::unique_ptr<T[]>

auto getLevelAsImage(int level) -> std::shared_ptr<Image>

Get a specific level in an ImagePyramid as an Image object. If requesting a level with a width or height higher than 16384 pixels this will throw an exception.

auto getPatchAsImage(int level, int offsetX, int offsetY, int width, int height, bool convertToRGB = true) -> std::shared_ptr<Image>

Extract a patch from the image pyramid and return it as an Image.

auto getPatchAsImage(int level, int patchIdX, int patchIdY, bool convertToRGB = true) -> std::shared_ptr<Image>

Extract a tile from the Image Pyramid.

auto getPatchAsImageForMagnification(float magnification, float offsetX, float offsetY, int width, int height, bool convertToRGB = true) -> std::shared_ptr<Image>

Get patch as Image at a specific magnification.
