Member Data Documentation

◆ bFloatingPointWindowValidity

int GDALRasterIOExtraArg::bFloatingPointWindowValidity

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

double GDALRasterIOExtraArg::dfXOff

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

◆ dfXSize

double GDALRasterIOExtraArg::dfXSize

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

◆ dfYOff

double GDALRasterIOExtraArg::dfYOff

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

◆ dfYSize

double GDALRasterIOExtraArg::dfYSize

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

◆ eResampleAlg

GDALRIOResampleAlg GDALRasterIOExtraArg::eResampleAlg

Resampling algorithm

◆ nVersion

int GDALRasterIOExtraArg::nVersion

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

◆ pfnProgress

GDALProgressFunc GDALRasterIOExtraArg::pfnProgress

Progress callback

◆ pProgressData

void* GDALRasterIOExtraArg::pProgressData

Progress callback user data
