![]() Set to 1.0 toĪGG/JPEG: The “QUALITY=n” option may be used to set the quality ofĪGG/PNG: “COMPRESSION=n” is used to determine the ZLIBĬompression applied to the png creation. This value is used to prevent artifacts fromĪppearing on the border of contiguous polygons. See Run-time SubstitutionĪGG/*: “GAMMA=n” is used to specify the gamma correction toĪpply to polygon rendering. (optional)Īll FORMATOPTION values can be replaced using runtime substitution. Statement may be present within a OUTPUTFORMAT declaration. Provides a driver or format specific option. Provide the extension to use when creating files of this type. TEMPLATE should be used for template based output. Output can be generated with either GDAL or AGG (AGG is generally moreĮfficient). For output through GDAL the GDAL shortname for theįormat is appended, such as “GDAL/GTiff”. For AGG, the possible driver names are “AGG/PNG” and “AGG/JPEG”.įor output through OGR the OGR driver name is appended, such as Names include the definition of the format if the driver supports multipleįormats. The name of the driver to use to generate this output format.
