GDAL's integer constants — gdal

The enumerators GDAL declares: data types (GDT_*), access modes (GA_*), colour interpretations (GCI_*), resampling algorithms (GRA_*, GRIORA_*), open flags (OF_*), error classes (CE_*, CPLE_*) and the rest. They are returned as one named vector rather than exported one by one, so that GDAL7 adds two names to the search path instead of two hundred.

Usage

gdal_constants(prefix = NULL)

Arguments

prefix: Optional. Keep only the constants whose names start with this.

Value

A named integer vector.

Details

A constant that the GDAL in use is too old to declare is absent from the vector. See gdal7_capabilities() for the same question about bindings.

Examples
