progressive preview for big images
Posted: Tue Nov 25, 2008 11:27 am
Hello, I don't know if this has been suggested somewhere else in another topic, but anyway, I did not find it:
For big files, it would be nice to have a progressive preview of it.
For Raws (if full-res) and big TIFFs, for example, it always takes a long time after double-clicking on the thumb until we see the image in XV.
But it could be appearing much faster because we don't need all the pixels of the image to give a window-fitting view of the image. Typically a 10 megapixel image is often 4 times bigger than the placeholder for the image in XV on most computers. So we need only one of 4 pixels.
The image only needs to be fully loaded when it's viewed at 100% zoom.
I think, I provided a poll for it, that:
A lot of users prefer to have a blurred or not perfectly correct preview of the image that appears INSTANTLY, rather than wait until XV fully loaded the image to finally see the image in a window-fitting size.
After having loaded the first instant preview, XV could work in background to open the image fully, while the user observes his preview.
I know of some users who are disappointed that they have to wait so long to open their big image files, because they don't know what XV is doing.
Now opening works perfectly, but we are not patient, and we often don't need the image to be fully loaded.
It may seem not so important, but subconsciously, people will be much more confident in their software if they see it reacting instantly.
