Constructor & Destructor Documentation

GDALImage()

GDALImage::GDALImage	(	std::string	filename,
		int	band = 1,
		int	cacheSizeInGB = 0,
		int	useMmap = 1 )

Constructor.

Create a GDAL image object

Parameters

filename	a std::string with the raster image file name
band	the band number
cacheSizeInGB	read buffer size in GigaBytes
useMmap	whether to use memory map

Member Function Documentation

loadToDevice()

void GDALImage::loadToDevice	(	void *	dArray,
		size_t	h_offset,
		size_t	w_offset,
		size_t	h_tile,
		size_t	w_tile )

Load a tile of data h_tile x w_tile from CPU to GPU.

Parameters

dArray	pointer for array in device memory
h_offset	Down/Height offset
w_offset	Across/Width offset
h_tile	Down/Height tile size
w_tile	Across/Width tile size

Note

Need to use size_t type to pass the parameters to cudaMemcpy2D correctly
