Hi Armin,

I have expanded the ideas surrounding some of your concerns. Indeed, there is NO method perfect for every situation.

Before presenting my new ideas, lets get a step back and see, where is this *selection* useful. When I select a number of objects, there are a number of common scenarios:
1. I wish to move the selection somewhere:
- border match: I wish to move the selection in such a way, that the border of one object is matched to that of a different object -colour match: the move should position one coloured object from selection in apposition to a specific colour of a non-selected object

2. I wish to make some global changes on all objects (or other possibilities) - won't be discussed here

So, in some situations I might want to have the border clear, while in others I wish the best view of the colours. In the first scenario, a border might be very counterproductive, while in the second, even an overlay will make colour finding/ adjusting/ visualizing a hard thing to do. These issues should always be kept in mind, when deciding how the selection should look like.

CON: With non-dashed, the current line style (if hairline) will not be WYSIWIG -> hard to change
CON: When hairline, hard to see at all (if not at least animated)
That's why i extended the line width and pained it transparent.

I would like the plain (little bit thicker, 0.04'') line. I would use this method on objects where the border is non-relevant. When the border is relevant, NO border-method will be optimal.

Do You talk about transparence or dashed? I already offered those.

NO. Draw a normal border, BUT not covering the border on its whole length. Draw it just over 40-70% of the border-zone, that is some of the border will remain visible as is. It might be useful, if I need to position 2 objects based on their borders, yet other methods are too complex (complex objects). I created this in my test case as if dropping a shadow (3D effect), but it is really about drawing only a portion of the border, NOT on the whole length.

PRO: Maybe a good way to do something with the whole selection, e.g. grab the point where all the arrows emerge and drag. There may be more useful. CON: There may be technical paintings which already have a lot of arrows, not good to distinguish CON: The arrow head is intended to point to the center of the selected object. Think about a shape in the form of a big "C" or "O" -> pointing to something completely different. Finding a good point for the arrow head will be hard (some KI ? :-))

Here is where I developed a nice solution. See the appended drawing, where I used some semicircular lines around the original line / border to draw attention to the selection. It looks really good. This is how you would do a *professional drawing* anyway. There remains the limitation of technical paintings with a lot of arrows, but as I said, for every method there are technical limitations.

> 2. FILL: change fill colour; there are various flavours, eg.

I would generally not change object props at all, may it be line or fill style or something else. I think we should agree in keeping the object visualisation as it is, keeping WYSIWIG. Let's look at the selection as extension of that visualisation -> Overlay. So i would prefer to 'Overlay' with something transparent or 'checkered' or so where the WYSIWIG object shines through.

Even with overlay, the colours are strongly distorted. So, if the user really needs the colour, this is as bad as a full fill. For very complex selections, having a full fill (*OR REVERSE THIS*) is quite powerful. I used it a lot in Photoshop (although for more complex drawings).

> 4. SELECTION MASK (ala Photoshop)

I would not offer the user another kind of view, the selection-mask-view. There are already enough views, for many users OOo still looks complex. We putted (and put) a lot of work to make things easier, so i dont think there is demand for a special view for working with the selection

Please let me tell you, that selection *MASKS* are one of the most complex things in drawings. In Photoshop, there are specialized plugins (quite expensive ones) to allow different masks. *You never have enough mask views!* simply because there is always a situation where all existing masks fail and working there is a hell. (and sometimes they fail grandiosely)

Just my two cents,

Leonard Mada
