Channel image output¶
Description¶
outputicon| The Channel image output displays a single channel as an image.
Ocean can display raw sensor values, but as the instrument characteristics are stored with the images, it can also compute radiometric or photometric quantities, depending on the instrument and sensor types. See quantities for more details. The values are then mapped to a selectable color gradient using linear or logarithmic scale, within the given range.
Children Nodes¶
This node has a filter list. It may have a variable number of filter children. The name of each filter is user-defined and does not affect the result.

Parameters¶
name | type | description |
---|---|---|
quantity | list | The photometric/radiometric quantity to display |
channel | string | The channel name |
colors | list | The color scale, can be grey, hue or thermal |
rangemax | real | The maximum value to display, values above are clamped. |
logarithmic | boolean | Use a logarithmic scale instead of a linear scale |
logdecades | integer | The number of decades displayed in logarithmic scale mode |
info | boolean | Overlays some information about simulation and software version on the image |
legend | boolean | Displays a scale legend |
grid | boolean | Enables grid display on the graphical user interface |
gridx | integer | Number of grid columns |
gridy | integer | Number of grid rows |
