With this icon you call up image processing tools; their appearance depends on the selected image type. With the tools you can modify duochrome palette images, duplex/triplex/quadruplex images and palette colour images. With other image types an error message appears.
The image processing tool is very simple to use: You will see a dialog that displays both colours used in the duochrome palette image.

In the selection popup at the top of the dialog you will see the
status of both colours: Custom
means that the colours no longer
correspond to the original colours after conversion of the image to a
duochrome palette image. With Black/white
you can recalculate
the image back into the normal black & white mode at any time.
To define custom colours, just click on one of the two small colour patches at top left of the colour list area. After this the Calamus Edit colour list dialog opens, in which you can choose any desired colour.

If you exit the Edit colour list dialog with the [OK] button (or with [Return]), the selected colour will be assigned to the previously clicked on palette colour of the image.

With this image processing tool you first have to determine what
type of nplex image
you want to process.

To do this, select the desired image type in the selection popup at the top of the dialog. Depending on what you have chosen, you will then see up to four image parameter lines in the dialog.

The lines are labelled Colour 1
to Colour 4
which is
followed by a control curve field, a colour field as well as a colour
name in each case.
If you only want to alter the colour(s), simply click on the large
colour fields. After this the Calamus Edit colour list
dialog
opens, in which you can choose any desired colour. If you exit the
Edit colour list dialog with the [OK] button (or with [Return]), the
selected colour will be assigned to the previously clicked on layer
colour of the image.
With greyscale or duplex images, this may be sufficient to achieve the desired effect in an image. But you can and should still take care to ensure that that the colours appear balanced with each other when mixed in the image.
To achieve this you can alter a gradation control curve for each colour. Click on the control curve field of the relevant colour. This opens the Control curve editor (e.g. FrankLIN, if you have loaded this as a module).

In the Control curve editor you can modify the gradation control
curve, and save or load modified curves. If you exit the Edit control
curve editor with the [OK] button (or with [Return]), the gradation
control curve will be assigned to the selected colour of the nplex
image, and you can see the changes directly in the document after the
Duplex options
dialog is closed.
Tip: For such work its best to use the extended Control curve editor FrankLIN from the start, which has to be loaded as a module. This offers a preview of the effect any changes and the possibility of modifying all the required control curves in one go.
This image processing tool is used in a similar way to that for duochrome palette images: You will see a dialog that displays the 256 colours of the palette colour image.

In the selection popup at the top of the dialog you will see the
status of the colour palette: Custom
means that the colours no
longer correspond to the original colours after conversion of the
image to a palette colour image. With Greyscale
you can
recalculate the image back into the normal greyscale mode at any time.

To define custom colours, just click on one of the two small
colour patches at top left of the colour list area. After this the
Calamus Edit colour list
dialog opens, in which you can choose
any desired colour. If you exit the Edit colour list dialog with the
[OK] button (or with [Return]), the selected colour will be assigned
to the previously clicked on palette colour of the image.
