super fast thumbnails not so fast

[влад]

I check this product and I see that generation of thumbnails is not really fast, even if the "super fast thumbnails" is checked on! I do not mean about caching. I refer to initial generation.
I compare with XNView and other products and all is faster than XY.
So maybe this feature needs some optimize?

Xnview is a Pro image viewer -won't you agree that it would be strange if a file manager would be faster than it

No, I not agree. Because it is important feature of modern file manager also to display thumbnails quickly. The option is advertised as "super fast thumbnails"! But in fact it is super-slow compared to most other products (not only XNView).
So it is definitely something that is misleading the user... Programmist of XY should rework the feature...

Creating thumbnails is done by Windows (GDI/GDI+), both super-fast or normal. Everybody out there uses the same functions. So there cannot be large speed differences. Only very specialized imaging software will code native thumbnailing code. I did this for TGA because they are not supported by GDI+.

OK, probably the GDI+ dont supports embedded thumbnails in jpeg. And therefore the listing appearas much faster in software which supports it.
Maybe you can think to add support for embedded jpeg thumbnails?

i'd want to take my part to say that all these "modern file managers" are so dumb and resource-consuming exactly because of such media/image "all-over previews" FM doesn't have to be "a wonderful image viewer" -there are many programs which a well done for that precisely. and if comparing, then lets compare Xnview as FM -i tried to use it so = almost horrible.

GDI+ does support embedded thumbnails through GetThumbnailImage() method of Image class: http://msdn.microsoft.com/en-us/library ... 85%29.aspx
