FrankLIN offers comprehensive options for selecting the control curves. It differentiates between control curves that are visible and those that can be edited. Visible control curves, as one can guess from their name, are those that can be viewed but remain unchanged by all operations. Editable control curves are those that are being modified at the time; all actions will operate on each of these control curves. This may sound a bit complicated, but it has its practical side. For instance it allows altering only a single control curve while its relation to the others remains visible at all times.
In order to make control curves visible or editable, one only has
to activate the
Edit checkbox(es) respectively
at the left of the control curve list so that they are crossed. Since,
logically, control curves that are not visible can also not be edited,
and, the other way round, editable curves have to be visible, FrankLIN
ensures that the selected checkbox combinations are sensible.
Provision has been made in FrankLIN to handle also control curve sets that contain more than seven individual control curves. Though applications for this are not found in Calamus as yet, it may be that this will be realised in the future via an additional module, for instance. Thus with FrankLIN you have at your disposal a future-proof tool that can deal with such demands as well.
In principle control curve types in Calamus can contain any number of individual control curves that in combination fulfill some kind of task. Although at present a maximum of 7 individual control curves are used, FrankLIN is already prepared for more (e.g. spot colours, 7-colour separations).
The lower part of the main dialog box contains the selection area. It consists of two columns with small checkboxes and one column of control curve names.
If you click on one of the checkboxes at far left, then the display of the corresponding control curve will be switched on (crossed) or off (uncrossed).
If you click on the checkbox on the right, an invisible control curve becomes visible and editable; with a control curve that is already visible this just switches between making it alterable and not alterable.
This difference may appear somewhat puzzling at first, but is extremely sensible: Only in this way, though you can see all the control curves, you are not forced to also edit all curves at the same time. In addition, you can for instance make a detour via the clipboard and copy the pattern to another (unedited) control curve, then modify existing control curves with any of FrankLIN's construction tools.
The button ALL activates all checkboxes.
The button NONE switches all checkboxes off.
The control curve names can not be altered at present. Depending
on the colour space of the image they are either
Black, Cyan, Yellow, Magenta. If at some time
Calamus should use more complex control curve types with more than 7
individual control curves, then you will be able to scroll through the
list of individual control curves with a scroll bar at the right of
the selection field.
Tip: If instead of clicking on one of the checkboxes before the control curve name you click directly on the control curve name itself, then all control curves except for the one clicked on will be switched off and the clicked control curve switched on for editing.
