GDALSetMetadataItem() not working in gdal 1.7

[christopheM]

The function GDALSetMetadataItem() has stopped working in gdal 1.7. A call to GDALGetMetadataItem() shows the metadata that I am trying to write, however the final file saved does not show any new metadata.

As a work around, GDALSetMetadataItem() works after a call to the function GDALGetProjectionRef(), code below:

hSrcDS = GDALOpen(fileName, GA_Update); added in order to have area_or_point metadata with 1.7.x release GDALGetProjectionRef( hSrcDS ); CPLErr err = GDALSetMetadataItem(hSrcDS,GDALMD_AREA_OR_POINT, GDALMD_AOP_POINT,NULL); const char* pixelOrPoint=GDALGetMetadataItem(hSrcDS,GDALMD_AREA_OR_POINT,NULL); GDALClose(hSrcDS);
