I'm loading rasters into a file geodatabase in Engine code. Some of them need reprojecting so I'm trying the following code:
// I have an IRaster pointed to by pRaster and a required ISpatialReference pointed to by pSpatialRef
VARIANT vMissing;
vMissing.vt = VT_ERROR;
vMissing.scode = DISP_E_PARAMNOTFOUND;
// Create a RasterTransformionOp to do the re-projection
CComPtr<ITransformationOp> pTransform;
hr = pTransform.CoCreateInstance(CLSID_RasterTransformationOp);
// get the IGeoDataset of the original Raster
CComPtr<IGeoDataset> pInGeoDataset;
hr = pRaster.QueryInterface(&pInGeoDataset);
// Project it into the new Spatial Reference
CComPtr<IGeoDataset> pOutGeoDataset;
hr = pTransform->ProjectFast(pInGeoDataset, pSpatialRef, esriGeoAnalysisResampleCubic, &vMissing, &pOutGeoDataset);
// Get the resulting RasterDataset
CComPtr<IRasterDataset> pReprojRasterDataset;
hr = pOutGeoDataset.QueryInterface(&pReprojRasterDataset);
// Get the reprojected raster from the new dataset
CComPtr<IRaster> pReprojRaster;
hr = pReprojRasterDataset->CreateDefaultRaster(&pReprojRaster);
// Load it into the existing File Geodatabase
hr = pRasterLoader->Load(pRasterDataset, pReprojRaster);
However, the resultant raster isn't reprojected. Any clues as to what I am mis-understanding?Chris
