Hi Stephane,
There is a misconception here. The dropdown control where you can select a view --which we call a
view selection list-- is not intended to select an image to be processed or modified by the process (RGBWorkingSpace in this case).
The purpose of a view selection list is to load image data or image properties into a particular processing window. However, as soon as you change one of these properties through a parameter of the process, the set of properties is no longer coherent with the current state of the image, and hence the view selection list changes to "no view selected". Bear in mind that PixInsight is a strongly dynamic environment --as soon as you change anything in an image, every interface item that depends on it changes (or this is what is intended to happen, bugs permitting).
Along with
dynamic, PixInsight's interface is
object-oriented. This means that images and processes are completely independent from each other: you don't need an image to define a process in PixInsight.
With RGBWorkingSpace, you just define the RGB space parameters as desired, then apply it to the image you want. You can do this in several ways; mainly two:
- By selecting the image and clicking the
Apply icon (blue, square). This is the same as pressing F5.
- By clicking the
New Instance icon (blue, triangular) and dragging it to the image.
This chapter of PixInsight LE's documentation explains the topic of view selection lists and interfaces in more detail. PixInsight LE is now an obsolete application, but most of its documentation is still valid for the PixInsight Standard platform:
http://pixinsight.com/doc/LE/10_processing_windows/image_independent_interfaces/image_independent_interfaces.htmlHope this will help you. Our interface is quite different from what is customary in most imaging applications. However, it is much more powerful and flexible. Once you feel comfortable with PixInsight's object-oriented interface, returning to simpler solutions will be very difficult
