Detailed Description

Function Documentation

boxFromPath()

OGREnvelope * boxFromPath ( const char * filePath, const char * layerName )

nodiscard

Compute the minimum bounding rectangle of the first or a specified layer and transform to EPSG:4326, if needed. All OGR-readable files and geometries are allowed.

Note

After the function returns, the caller owns the returned OGREnvelope object and musst free it after use with CPLFree.

Parameters

filePath	Path to file holding area of interest
layerName	Layer to use for bounding box creation. If NULL, use the first layer.

Returns

OGREnvelope* Reference to bounding box, NULL on error.

printBoundingBox()

void printBoundingBox

(

const OGREnvelope *

box

)

Print the top, right, bottom and left coordinates defining a bounding box to stdout.

Parameters

box	Bounding box whose coordinates should be printed.
