davidtayhs Posted August 8, 2006 Share Posted August 8, 2006 I resized an identical photo using similar DPI with Paint.NET and with another freeware prog that used the Lanczos filter. The result was better in the other software. Curious as to whether there is any technical stuff that I need to know to improve my resizing in Paint.NET?

RejZoR Posted August 8, 2006 Share Posted August 8, 2006 You can see what algorithm will be used for resizing when you input new values. It's usually supersampling or bicubic resampling, depending on in what direction you're resizing. Supersampling is usually the best you can get as it's also quiet demanding operation.

barkbark00 Posted August 8, 2006 Share Posted August 8, 2006 English version only has these options...not sure what they're called in different lang versions. Quote Take responsibility for your own intelligence. 😉 -Rick Brewster Link to comment Share on other sites More sharing options...
RejZoR Posted August 8, 2006 Share Posted August 8, 2006 Supersampling is usually used for drastic downsamplings (like from 1024x768 to 640x480). Though too bad that we can't select Super Sampling on our own... Quote Link to comment Share on other sites More sharing options...
barkbark00 Posted August 8, 2006 Share Posted August 8, 2006 I thought davidtayhs was talking about enlarging an image? I'm not trying to say that I knew that about Super Sampling....

davidtayhs Posted August 9, 2006 Author Share Posted August 9, 2006 I often reduce and enlarge photo sizes depending on my need. Compared the results of Bicubic resampling with that of Lanczos and thought the latter gave better results. Wonder if there are bicubic resampling tricks that I don't know about? Don't think our English version has the supersampling feature. Quote Link to comment Share on other sites More sharing options...
Crazy Man Dan Posted August 9, 2006 Share Posted August 9, 2006 It only uses Super Sampling if it thinks it needs it. Set the Quality to Best Quality and size down. Look at the readout at the bottom, and you'll see it says: *Super Sampling will be used.

davidtayhs Posted August 10, 2006 Author Share Posted August 10, 2006 Wonder why some of us only have "*Bicubic will be used" as the "Best Quality" Resampling? whilst others have some "Supersampling" option that appears? Quote Link to comment Share on other sites More sharing options...
Rick Brewster Posted August 10, 2006 Share Posted August 10, 2006 Depends on what the target size is. If you are shrinking, it uses super sampling. Enlarging uses bicubic.

davidtayhs Posted August 10, 2006 Author Share Posted August 10, 2006 Thanks for the most helpful answers. Checked the resampling filter once again when I was reducing the photos and was shocked to see that it was really supersampling! Apologies for my confusion but how does supersampling compare with Lanczos? Any answers? Quote Link to comment Share on other sites More sharing options...
