Image Quality in SlideShow

I am trying to start a slide show on a folder of images of lower size. When I select the images seperately, they are scaled to full view with high quality. This option seems not to work when I start the a slideshow with CTRL-L on a folder. I can select "high quality" for the slide show, but this option doesn't seem to work. When I use the quick slide show (SPACE-Bar), images are scaled in high quality as selected.

I am using 1.80.3 in the german version. I necessary, I could install the english version to name the exact menu entries that I've been chosen ...

Greetings
Helmut

In classic slideshow, if you have "use high quality", picture are not scale with high quality??

That's what I meant.

If I start a slide show with options "Fullscreen", "Stretch small pictures" and "Use high quality", the images are scaled different from viewing them directly in full screen mode with options "Fit image to window, all" and "High quality zoom, Enlarge". Is this behaviour as desired?

Hum, strange, but how do you see the difference?

Just use a tiny image (e.g. 100x100) and view it full screen. If enlarged in low quality, you can see the squared pixels, while in high quality, it should be something smoothened (non squared).

Toggeling the "Use high quality" switch in the SlideShow options has no effect in the slide show for me. (I also checked it in the alpha version). Maybe there is a dependency to the transition effects, which are not active in normal viewing? Some versions ago, full screen enlargement didn't work at all in slideshows, when transitions were switched on.

Oh yes, right. I think that view little picture must not be smoothed like in slideshow, what do you think?

The 100x100 example is the extrem, but when enlarging photos, they appear pixelish, if not scaled with high quality. In normal viewing mode, you got seperate quality options for enlarging and shrinking. Does the single High Quality switch in slide shows only stands for shrinking images? In that case I would request another option for high quality enlargement :)

2 options is better like view mode, right??

There was another topic similar to this, but about the preview image in browser mode. It was determined in that case that the high quality zoom only worked when reducing the image, not when enlarging it.

I just tried this case, and it enlarged the image using high quality zoom. I have version 1.80.1.

Mmh, I just downdated to 1.80.1 and could reproduce the topic about the preview images, which do not get enlarged in high quality (there's also only a single option for that). But I did not manage it to see them in high quality as you did :? (at least not in preview or slideshow mode).

Actually I don't care about one or two options. But if there's only a single "High Quality"-option, it should work for both: shrinking and enlargement.

They aren't in high quality for me in preview mode, only in slideshow mode.

Ooops, you're right. It works on my other machine. It seems to depend on the system. The high quality slideshow works on my Windows XP host, while it's not working on my Windows 98 host. Is that possible?

Are you certain you have the same settings in both cases?

You could be right though, I'm on XP.

Yes, on 98 there is some problem

So is it good to have an option for high quality when enlarging and shrinking?
