ossimImageHandlerFactory() [1/2]

ossimImageHandlerFactory::ossimImageHandlerFactory ( )

inlineprotected

Open method that looks at extension e.g.

"tif", "jpg" to select class to open.

This is to be called by standard open before just going down the list of classes the brute force hard way.

Parameters

fileName

The filename to open.

Returns

Pointer to image handler or null if nothing opened.

openSrcRecord()

ossimRefPtr< ossimImageHandler > ossimImageHandlerFactory::openSrcRecord ( std::shared_ptr< ossim::istream > &  str, const std::string &  connectionString, bool  openOverview  ) const

protected

Open dot.src (ossimSrcRecord).

Currently only opens a single image. Can be used for split base image with overviews and histograms in a separate "support" directory.

Input record example:

ossim_src_record_version: 1.0 image0.entry: 0 image0.file: s3://your_bucket/data1/test/data/public/tif/ls7-ff-fusion.tif image0.ovr: /data1/s3_test/ls7-ff-fusion.ovr image0.hist: /data1/s3_test/ls7-ff-fusion.his image0.support: /data1/s3_test

Parameters

str	Open stream to src record.
connectionString	Path to src file.
openOverview	If true attempt to open overview file.

Returns

ossimRefPtr to image handler on success or null on failure.
