getImageGeometry() [1/4]

bool ossimTiffInfo::getImageGeometry	(	ossimKeywordlist &	geomKwl,

Extracts geometry info to keyword list.

This method assumes that open has been called and theFile is set.

Populates the keyword list with image geometry information. This method is used to relay projection/model information to users.

Parameters

geomKwl	Keyword list that will be initialized with geometry info. Returns true if geometry info is present, false if not.
entryIndex	Entry to get geometry from.

Extracts geometry info from stream to keyword list.

Populates the keyword list with image geometry information. This method is used to relay projection/model information to users.

Note

The str should be position at start of tiff portion. This was written to allow passing a stream positioned at an embedded tiff image in a jp2 file.

Parameters

str	Stream position at start of tiff image.
geomKwl	Keyword list that will be initialized with geometry info. Returns true if geometry info is present, false if not.

		ossim_uint64	geoAsciiLength,
		ossim_int8 *	geoAsciiBlock,
		ossimKeywordlist &	geomKwl
	)		const

Extracts geometry info from geotiff keys to keyword list.

Helper method used to extract keywords from geotiff keys embedded in files, e.g. LAS data. Because this is just the geotiff keys, the output will be missing the image part, i.e. line, samples, radiometry...

This output is intended to be usable to get a projection from a call to ossimProjectionFactoryRegistry::createProjection(kwl).

Internally calls printGeoKeys and then the private getImageGeometry.

Parameters

geoKeyLength	Length of geoKeyBlock.
geoKeyBlock	Pointer to array of keys.
geoDoubleLength	Length of geoDoubleBlock.
geoDoubleBlock	Pointer to array of double values.
geoAsciiLength	Length of geoAsciiBlock.
geoAsciiBlock	Pointer to array of ascii values.
projKwl	The keyword list to initialize.

Returns

Because the resulting keyword list (geomKwl) is not complete there will be no return.

printGeoKeys()

	)		const

Prints geo keys to stream.

Helper method used to extract keywords from geotiff keys embedded in files, e.g. LAS data. Because this is just the geotiff keys, the output will be missing the image part, i.e. line, samples, radiometry...

This output is the raw tiff tags/geotiff keys not necessarily useable to construct a projection from.

Parameters

out	Stream to dump to.
prefix	if any. This will be added to the keys, e.g. tiff0.coord_trans where "tiff0." is the prefix and "coord_trans" the key.
geoKeyLength	Length of geoKeyBlock.
geoKeyBlock	Pointer to array of keys.
geoDoubleLength	Length of geoDoubleBlock.
geoDoubleBlock	Pointer to array of double values.
geoAsciiLength	Length of geoAsciiBlock.
geoAsciiBlock	Pointer to array of ascii values.
