Windows scaling icons

Post by Dirk13 » Sat Mar 22, 2014 9:32 pm

Hello.
In Windows, at least Vista and newer, you have the display option to enlarge fonts and icons. Options include 125% and 150%.
http://www.techrepublic.com/blog/window ... i-scaling/
This is quite helpful for high-resolution screens, especially on notebooks.

But when trying this with my Win 7 and XnView 2.x,
I had the impression, that while fonts were indeed bigger, XnView's icons were not enlarged, but stayed at 100%. Why that?
I use the preset "Default" theme.

In other programs like LibreOffice, Thunderbird, etc. icons were definitively larger.

Thank you!

Hello Pierre,
usually, the icons are simply scaled up.
In some programs, where they are
a) vector graphics, they are enlarged better,
but in many other programs, the
b) bitmap-icons are simply scaled up - even if the look less "sharp" or clear. Kind of interpolated.

Is there any way to activate b) ?

Oh, what a pity.

I suppose, it's the same with your new XnViewMP?
Then my father will get some problems with using XnView on his new 1920*1080 notebooks... the trend goes to higher resolution screens, 4K on the desktop.

Strange, I thought that scaling would be managed directly by Windows for all applications.

I thought that using a Custom scaling would map everything on the screen to a larger size, but I have my screen set to 110% and when I looked closely I noticed that the XnView icon was slightly smaller than the other icons. Googling, I found that the icon size in Windows (Seven x64 in my case) can be controlled directly using Ctrl + Scroll wheel on the desktop -- it worked (except for the XnView icon) but also rearranged all my icons...

I imagine icons aren't mapped directly with other items on the screen to avoid the possible degradation you mentioned.

Rescaling works for the XnViewMP and XnConvert icons, I think.

What do you mean by "mapped"?

My reply related to the size of program icons on the desktop, as described in the Microsoft link above, but I see now that you had in mind the thumbnail overlay icons in XnView, sorry about the confusion.

Well, in everyday life a 'map' as you know represents part of the (spherical) earth on a flat piece of paper; more generally, in mathematics 'mapping' has a much more general meaning: 'The correspondence of elements in one set to elements in the same set or another set' to quote from one dictionary. An example of mapping that we can relate to more easily would be the display of a 1600 x 1200 pixel image on a 1024 x 728 pixel monitor, where the pixels in the image have to be 'mapped' in some way onto the smaller pixel dimensions of the screen. possibly resulting in a rather unsatisfactory image...

Oh, I know that in computer science, a "map" shows a relation between elements - one-to-one, or one to many.
But I have used it so far only for discrete elements, and not for factors of projection.
But all right, I'm no native speaker - and I'm no GUI programmer. ;-)
