RC5: Preview still built in two steps

Post by Lesmo16 »

Hm, there's a new flaw since RC5.

The previews of my digicam JPEGs are built in a kind of two small steps.

1) the complete preview image is visible - it looks unnaturally sharp
2) the complete preview image is drawn twice on top, it seems if it's drawn 1 or 2 pixels to the left and 1 pixel to the top - now it looks smoother and naturally.

I've seen something like that from an other photo program (can't remember which).

Yes. First the plain (low-q) image is being displayed and then some kind of anti-aliasing filter is being applied seemingly. Which is especially bad for graphic files like GIFs.

It must be something like that - but with JPEG.

I never said it only happens with GIFs. It happens with all image filetypes.

Yes, i have added a timer to show high quality picture. When you have big picture, you have low quality first, and high quality 500ms after...

Is it really annoying? Picture is seen more quicker, and after in high quality...

I could get used to it. It's just a preview after all.

Good idea, but it is very annoying with small images...

Maybe, use it only for large image...

It's absolutely annoying.
I prefer to wait a little, instead of getting crazy by those pumping images. :mrgreen:

Very good idea - support! :)


@xnview:
Pierre, what do you think about making something similar to:
Options -> Browser -> Thumbnail -> "No thumbnail for files larger than" 1024

For example:
Options -> Browser -> Preview -> "Smaller delay for files larger than" 4096
This option checked will act like RC5, unchecked like previous versions.

To be quite honest it's very annoying, however large is the pic to preview. I don't want to sound selfish but users on slow computers should have disabled High Quality Preview in the first place, there's no reason why others should put up with a 500ms transition.

The delayed updating is annoying and irritating. Nothing else to add to the comments above - apart that it's not needed and wanted on fast computers.

Seems you love that feature! :mrgreen:

But IMO - No, please not in fullscreen, too.
Perhaps you should think about my suggested option? :wink:
