You will notice in the thread that there are several messages, including
one that improve further the initial suggestion, thanks to marsh's feedback.
In my proposal, if you set border1 to (x=0,y=0) and border2 to (x=1,y=1), you will get exactly what Clo proposed, that is a thin simple frame around each thumbnail
(but you could choose whatever you want...), thus my previous message.
Current situation in XnView
If you set two different colors for "Background" and "Thumbnail back", check them and uncheck "flat style", you will notice that there are currently 3 areas around thumbnails:
- the "Thumbnail back" that fill the thumbnail frame and add a 2 pixels edge around the thumbnail.
- the "3D area" used to make a 1 pixel large 3D effect around the frame (this area does still exist in "flat style": it just takes the color of the background).
- the "Background" that separates each frame, and is 2 pixels large.
My improved* suggestion is to provide control for size (x and y) and color for each of those 3 areas:
- choose the "Thumbnail back"(I will call it "Frame") edge size around the thumbnail, and color
- choose the size for the "3D effect" (0=none), and the two colors used
- choose the size for the "Background"(I will call it "Separation"), and color
Some people may like larger 3D effect, larger frame around the image, single pixel separation (as Clo proposed) or even no separation at all...

It would even be possible to make something like the first suggestion of this thread.
It could look like this:
Code: Select all
...
- Frame X=[] Y=[] Color=[]
- 3D effect X=[] Y=[] Color(light)=[] Color(dark)=[]
- Separation X=[] Y=[] Color=[]
...
There would be no 'check/uncheck' box for them. "Flat style" would disappear (as you can choose X=0, Y=0 in 3D effect).
What do you think about this suggestion?
