Image Layer (common)¶

An Image Layer is any layer that loads and display tiled imagery on the globe. Image layers are stacked, rendered in order of appearance in the Map. In the earth tile, an Image Layer usually has an Image suffix.

Inherits from: Tile Layer

Property	Description	Type	Default
accept_draping	Whether draped overlays should be rendered on this layer	bool	true
altitude	Distance from the ellipsoid at which to offset the rendering of this image layer	float	0
mag_filter	Mip-mapping magnification filter (see `osg::Texture::FilterMode`for options)	string	LINEAR
min_filter	Mip-mapping minification filter (see `osg::Texture::FilterMode` for options)	string	LINEAR_MIPMAP_LINEAR
nodata_image	Location of an Image that represent "no data" for a tile.	URL	none
shared	Whether to allocate a dedicated texture image unit for this layer so that its data may be shared with other layers' shader code	bool	false
shared_matrix	When `shared` is true, name of the texture matrix uniform that applies to the shared texture for this layer	string	(auto generated)
shared_sampler	When `shared` is true, name of the sampler uniform that references the shared texture for this layer	string	(auto generated)
texture_compression	Controls whether and how to compress textures for the GPU. `auto` : automatically select a compression method `gpu` : use hardware compression if available `cpu` : use CPU compression if available `none` : do not compress textures	string	none
