Now we've got the whole digital camera thing happening, we have heaps of images that we need to resize, normally smaller.

Even things like shrinking them to avatar size, the images always get blurry.

So, q. is, whats a good tool to resize images downwards, is it possible to keep the images sharp?

Get a prgoram called ACDsee its great for resizing lots of images at once.

By reducing the resolution you are throwing away image data so your going to loose quality but the counter act this try using the least amount of compresion you can, the best method is just trail and error.

You should try using the demo on Paint shop Pro 7 or even MS Photo Editor.

Usually when shrinking images (the dimensions not the file size) they become sharper because you have the same amount of info in a smaller area, hence increasing the resolution. Usually this will not drop the file size by very much if at all.

The other way is to lose some quality, but because you have shrunk the dimensions down, again it shouldn't make a difference on the visable quality unless you zoom in. In fact many movies on the internet - think porn or drift :) - are in piss small dimensions, not because it saves on file size, but it allows them to chop out more data (that is what reduces the file size)without it affecting how it looks.

Basically if you have a semi decent program (there are many freeware and cheap ones out there), you shouldn't have a problem with resizing images. Try znet or cnet or download.com

Sorry to go on, probably more then you wanted, but anytime you need to be bored I'm your man.

Cheers,

Tim

Thanks for your help guys. I've downloaded ACDSee and will give that a whirl coz its named after australia's greatest band.

Yes, I was trying to reduce the resolution, not the actual size in bytes of the file, eg. to turn 640x480 into 100x100 for an avatar.

      Block bump. $400. As above cyl 6 needs bore or sleeve.

      I would think making the argument that the travel is limited by a spring flexing against a spring perch as "the same method". Later on in the document they do state that the spring can't bind on full bump travel and cannot come loose in full rebound travel as well. (which is all very sensible). The laws are actually pretty sensible and reasonable. It's just that the people who enforce and check them don't actually read them or know them accurately. "Oh, coilovers? Instant fail mate. Don't even need to look at it." - Guy who will be instantly reported by me. There is probably merit to people who do get defected for height also get defected for the suspension in that state that allows it. I did never consider the people who are complaining about coilovers being picked on are also running around at 50mm off the floor.

      Ethanol Content Sensor - Always at 11%?

      By Kinkstaah · Posted

      I think given SAU's knowledge of E85 we can strongly conclude that 10% ethanol in almost any situation is entirely fine. Almost all of the myths against E85 were overblown, let alone E10.

      From your link See bold text, is this referring to damper settings, if so that may a issue for "some" inspectors, I cannot see aftermarket coilovers having the evidence that "must be available that its functional performance is equivalent to the original" Maybe just remove the adjustment knows and hope for the best???? Meh 5.2 Suspension travel In all instances, modifications to a vehicle’s suspension must ensure the integrity of the system and not compromise the ride quality. At least two thirds of the original suspension travel should be maintained in both directions (rebound (i.e. extension) and bump (i.e. compression)), and rebound must be limited by the same method used by the vehicle manufacturer or if this is not practicable due to the nature of the modification, an equivalent method. If an alternative method is used, evidence must be available that its functional performance is equivalent to the original.

      They actually don't - They adhere to VSB14 rules just like Victoria. The rules are against CABIN adjustable height, and it quite clearly states that the height has to be within parameters. I asked the VASS engineer to confirm this when I got my car engineered and they refused to engineer the coilovers because they didn't meet the requirements for requiring engineering. (mine are height adjustable.) People "Not wanting to bother" with "Actually reading/knowing/adhering to the rules" should result in fines and immediately losing the ability to issue blue slips and/or RWC's in Vic.
