Set look-up table (LUT) for an image or a specific channel of an image.
Set look-up table (LUT) for an image or a specific channel of an image. The look-up table determines what colour ImageJ will render each intensity value of an image.
Input image: Image to set look-up table for.
Channel mode: Control if the same look-up table is applied to all channels, or just one:
- "All channels" Apply the same look-up table to all channels of the input image.
- "Specific channels" Only apply the look-up table to the channel specified by the "Channel" parameter. All other channels will remain unaffected.
Channel: When in "Specific channels" mode, this is the channel the look-up table will be applied to. Channel numbering starts at 1.
Lookup table: Look-up table to apply to the relevant channels. Choices are: Grey, Red, Green, Blue, Cyan, Magenta, Yellow, Fire, Ice, Jet, Physics, Spectrum, Thermal, Random.
Display mode: Controls how the minimum value in the look-up table should be rendered:
- "Full range" Use the full colour range of the look-up table. This is the default look-up table without modifications.
- "Set zero to black" Uses the standard look-up table, except for the lowest value, which is always set to black. This is useful for cases where the background will be 0 or NaN and should be rendered as black.
