Type Definitions

GeoTIFFImage{Object}

Properties:

Name	Type	Description
fileDirectory	Object	The file directory.
geoKeys	Object	The parsed geo-keys.
littleEndian	boolean	Uses little endian byte order.
tiles	Object	The tile cache.
isTiled	boolean	The image is tiled.
getBoundingBox	function	Get the image bounding box.
getOrigin	function	Get the image origin.
getResolution	function	Get the image resolution.

Options{Object}

Properties:

Name	Type	Argument	Default	Description
sources	Array.<module:ol/source/GeoTIFF~SourceInfo>			List of information about GeoTIFF sources. Multiple sources can be combined when their resolution sets are equal after applying a scale. The list of sources defines a mapping between input bands as they are read from each GeoTIFF and the output bands that are provided by data tiles. To control which bands to read from each GeoTIFF, use the bands property. If, for example, you specify two sources, one with 3 bands and nodata configured, and another with 1 band, the resulting data tiles will have 5 bands: 3 from the first source, 1 alpha band from the first source, and 1 band from the second source.
opaque	boolean	<optional>	false	Whether the layer is opaque.
transition	number	<optional>	250	Duration of the opacity transition for rendering. To disable the opacity transition, pass transition: 0.

SourceInfo{Object}

Properties:

Name	Type	Argument	Default	Description
url	string			URL for the source GeoTIFF.
overviews	Array.<string>	<optional>		List of any overview URLs.
min	number	<optional>	0	The minimum source data value. Rendered values are scaled from 0 to 1 based on the configured min and max.
max	number	<optional>		The maximum source data value. Rendered values are scaled from 0 to 1 based on the configured min and max.
nodata	number	<optional>		Values to discard. When provided, an additional band (alpha) will be added to the data.
bands	Array.<number>	<optional>		Band numbers to be read from (where the first band is 1). If not provided, all bands will be read. For example, if a GeoTIFF has blue (1), green (2), red (3), and near-infrared (4) bands, and you only need the near-infrared band, configure bands: [4].
