Comments

The Remap Intensity dialog.

This dialog has the following fields:

Channel Drop-down list box:

Use this to select the channel to remap. There are four choices:

• RGB: remap all channels.

• Red: remap the red channel.

• Green: remap the green channel.

• Blue: remap the blue channel.

Curve Mode Drop-down list box:

Use this to select the curve mode to use when remapping. There are four choices:

• 

  Curve: remaps the selected channel using curve data.

• 

  Linear: remaps the selected channel using linear data.

• 

  Exponential: remaps the selected channel using exponential data, which is affected by the Factor value.

• 

  Logarithm: remaps the selected channel using logarithmic data, which is affected by the Factor value.

Factor Edit box:

Use this to set the factor of the Exponential/Logarithm curve. Enter the value directly in the edit box or use the arrows to set the desired value.

Flip Buttons:

Use these buttons to flip the curve if the Curve Mode is either Curve or Linear. The following options are available:

• 

  Both. Flip the curve vertically and horizontally.

• 

  Vertically. Flip the curve vertically.

• 

  Horizontally. Flip the curve horizontally.

Reset Button:

Use the Reset button to set the curve of the current channel to default values.

Reset All Button:

Use the Reset All button to set the curve for all the channels to default values.

Load Button:

Use the Load button to load an "*.lri" file that contains Remap Intensity curve settings, using the Load dialog. The loaded file will set a new curve for each channel.

NOTE: Loading curve settings will overwrite all current settings for all channels!

Save Button:

Use the Save button to save all the curve settings for all the channels into an "*.lri" file. This allows you set the same curve settings for other images by re-loading the file.
