Image quality good even when scaled. Why?
There's something I have been wondering about. Usually when an image is scaled in a Flash presentation it looks crappy. Yet, with ImageVue galleries no matter how scaled the image is, it still looks good. Can someone explain to me why this is so?
That's an interesting question -
I still think quality is degraded somewhat when scaling an image, and images are always at best quality at 100% of original size (both scaling up and scaling down causes somewhat quality loss, although there is less loss with scaling down)
We use a setting in the Imagevue slideshow _quality = "best"
Which somewhat improves the image smoothing and anti-aliasing when it's being scaled. The default setting is "high". Below see how the Flash documents describe the settings:

_quality = "best"Adobe wrote:"HIGH" High rendering quality. Graphics are anti-aliased using a 4 x 4 pixel grid, and bitmaps are smoothed if the movie is static. This is the default rendering quality setting used by Flash.
"BEST" Very high rendering quality. Graphics are anti-aliased using a 4 x 4 pixel grid and bitmaps are always smoothed.
