}

Structure to pass extra arguments to RasterIO() method, must be initialized with INIT_RASTERIO_EXTRA_ARG @since GDAL 2.0

Fields

nVersion: c_int

Version of structure (to allow future extensions of the structure)

eResampleAlg: Type

Resampling algorithm

pfnProgress: GDALProgressFunc

Progress callback

pProgressData: *mut c_void

Progress callback user data

bFloatingPointWindowValidity: c_int

Indicate if dfXOff, dfYOff, dfXSize and dfYSize are set. Mostly reserved from the VRT driver to communicate a more precise source window. Must be such that dfXOff - nXOff < 1.0 and dfYOff - nYOff < 1.0 and nXSize - dfXSize < 1.0 and nYSize - dfYSize < 1.0

dfXOff: f64

Pixel offset to the top left corner. Only valid if bFloatingPointWindowValidity = TRUE

dfYOff: f64

Line offset to the top left corner. Only valid if bFloatingPointWindowValidity = TRUE

dfXSize: f64

Width in pixels of the area of interest. Only valid if bFloatingPointWindowValidity = TRUE

dfYSize: f64

Height in pixels of the area of interest. Only valid if bFloatingPointWindowValidity = TRUE
