Resampling algorithm to use
data type to use during warp operation, GDT_Unknown lets the algorithm select the type
GDALDatasetH GDALWarpOptions::hDstDS |
Destination image dataset - may be NULL if only using GDALWarpOperation::WarpRegionToBuffer().
GDALDatasetH GDALWarpOptions::hSrcDS |
Source image dataset.
Number of bands to process, may be 0 to select all bands.
The dest. band so use as an alpha (transparency) value, 0=disabled
The source band so use as an alpha (transparency) value, 0=disabled
The "nodata" value imaginary component - may be NULL even if real component is provided.
The "nodata" value real component for each output band, if NULL there isn't one
The "nodata" value imaginary component - may be NULL even if real component is provided.
The "nodata" value real component for each input band, if NULL there isn't one
The band numbers for the destination bands to process (1 based)
The band numbers for the source bands to process (1 based)
A string list of additional options controlling the warp operation in name=value format. A suitable string list can be prepared with CSLSetNameValue().
The following values are currently supported:
Normally when computing the source raster data to load to generate a particular output area, the warper samples transforms 21 points along each edge of the destination region back onto the source file, and uses this to compute a bounding window on the source image that is sufficient. Depending on the transformation in effect, the source window may be a bit too small, or even missing large areas. Problem situations are those where the transformation is very non-linear or "inside out". Examples are transforming from WGS84 to Polar Steregraphic for areas around the pole, or transformations where some of the image is untransformable. The following options provide some additional control to deal with errors in computing the source window:
GDALProgressFunc GDALWarpOptions::pfnProgress |
GDALProgressFunc() compatible progress reporting function, or NULL if there isn't one.
Type of spatial point transformer function
Callback argument to be passed to pfnProgress.
