channelsHow the samples in the GeoTIFF files (also known as bands), are mapped to the color channels of an RGB(A) image.
Must be an array of either 1, 3 or 4 elements. Each element is the index of a sample in the
source file. For example, to map the samples 0, 3, and 2 to the R, G, B colors, you can use
[0, 3, 2]
.
Note: if the channels is undefined
, then they will be selected automatically with the
following rules: if the image has 3 or more samples, the first 3 samples will be used,
(i.e [0, 1, 2]
). Otherwise, only the first sample will be used (i.e [0]
). In any case,
no transparency channel will be selected automatically, as there is no way to determine
if a specific sample represents transparency.
[1]
[0]
[0, 0, 0, 1]
[0, 1, 2]
[0, 1, 2, 3]
[1, 1, 1, 3]
[2, 1, 0]
Optional
colorThe custom color space of the generated textures.
See https://threejs.org/docs/#manual/en/introduction/Color-management for
more information. If unspecified, the source considers that 8-bit images are in the sRGB
color space, otherwise NoColorSpace
.
Optional
containsThe custom function to test if a given extent is contained in this source. Note: we assume this function accepts extents in this source's CRS.
The Coordinate Reference System of the image.
Optional
flipYShould images be flipped vertically during composition ?
Optional
is8bitThe data type of images generated.
For regular color images, this should be true
. For images with a high dynamic range,
or images that requires additional processing, this should be false
.
Optional
synchronousIs this source able to generate images synchronously ?
The URL of the COG image.
