Validate the list of creation options that are handled by a driver

Description

validateCreationOptions() is a helper function primarily used by GDAL's Create() and CreateCopy() to validate that the passed-in list of creation options is compatible with the GDAL_DMD_CREATIONOPTIONLIST metadata item defined by some drivers. If the GDAL_DMD_CREATIONOPTIONLIST metadata item is not defined, this function will return TRUE. Otherwise it will check that the keys and values in the list of creation options are compatible with the capabilities declared by the GDAL_DMD_CREATIONOPTIONLIST metadata item. In case of incompatibility a message will be emitted and FALSE will be returned. Wrapper of GDALValidateCreationOptions() in the GDAL API.

Usage

Arguments

format	Character string giving a format driver short name (e.g., "GTiff").
options	A character vector of format-specific creation options as "NAME=VALUE" pairs.

A logical value, TRUE if the given creation options are compatible with the capabilities declared by the GDAL_DMD_CREATIONOPTIONLIST metadata item for the specified format driver (or if the GDAL_DMD_CREATIONOPTIONLIST metadata item is not defined for this driver), otherwise FALSE.
