How to remove pixelization enlarging small image?

one person's waste of time is another person's quest for the holy grail

I have lost count of the number of things I have learned by persuing things that did not work....

Indeed, but that's not the 'quest' here.

alas poor metaphor, I knew thee

its for wallpaper, desktop presumably and therefore likely a personal thing

we don't all think the same way

All I said was it was a waste of time enlarging it. A comment made into a saga..

'twas the way you said it

who are any of us to decide it would be a waste of time when we don't have enough info to make that call - I have lots of images that I have no idea where they came from and the likes of tineye draw blank - and it could be a treasured family photo or such - we don't know do we...

There is a proprietary format called Deja Vu that uses affine transforms (maths) to encode images. It is the closest thing to curved edges and not pixelation you will find. There used to be a free editor available.

Use some of the on-line searches for images and you may find a larger version.

What resolution is the image and what is your desktop resolution?

DJV[U] files...? that's a format for mixed content, so in that sense similar to PDF, possibly epub formats too...

I'm a great believer in Shutterstock.com They have an excellent selection of images, and if take one of their packages the images are very reasonable. Something like $10-15 per download. Life is short.

whilst I agree with life being short I can't help but feel that the consensus of this thread is that the OP should be doing something other than what they actually asked for help about

I'd say my advice was very much to the point. If you have a better solution, I'd be happy to hear and it I'm sure the OP would too.

All of the 'solutions' to enlarging images from smaller to larger sizes involve losing definition resulting in blurry images or heavily processed imagery that are unnatural - usually sharpening techniques of the blurred images. Some years ago there was a flurry of activity based around fractal encoding of images so they could be zoomed in infinitely without pixelating, but I'm not sure these days where that software went and I don't think that technique could create detail where there was none.

This is again a thread where a OP asks a question and leaves us to wonder the exact circumstances behind the question so that we can offer the best way forward even if it's not exactly the answer that the OP wanted to hear.

Often the best answer to a question is the one that provides the best overall solution rather than simply answers a question that may be unanswerable or indeed the wrong question for the circumstance.

[edit: My guess is that Mirkosoft may want to enlarge old 8-bit and 16-bit game imagery from the past ]
