Would you like to take the middle image from post #11, take the top left small bit and scale it up very high (800%) and cut out the bit of petal like the others so we can compare ?

Here is another freeware application that provides a few other enlarging modes:

Here are some results:

Thats brilliant Rob. Are you able to edit the post and label them as to what they mean. I have to say I do not think that they are an improvement over ordinary methods tho. The one Mathuwm suggested is critically acclaimed and supposed to be very good indeed so I am curious. It appears I have repped you enough already

I am expecting great things from this super resampler but I cant accept this. This is too good. Is this the small image in the top left of the middle image of post 11 - I have attached it again below. How can it reproduce perfect stamen from a single pixel... tell me this was from a different image !
Can you do the image attached at 800% or x8 mag ?
Edit -- I can see that this must have come from top left of post #2 and not post #11. Its still very good but it would be great to have a side by side comparison from the same source.

the 120x96 pixal image
No i do not think that would work to well.
the larger the image the better it upscales
this program is used a lot for upscaling images for printing on a large format printer
what i did was take this:
Image size-1.png
and scale it to this
I actually cropped it after I scaled it so the actual differences might be slightly off

Well the little one is whats being used for all of these samples just so we can compare what a small image resampled would become under different algorithms. Its looks from the dialog images as your using Bicubic in any case - unless it says that when using the Genuine Fractals anyway.
Just for reference, here is my GTS doing it. I will have to look at the source to see what kind its using. I think its Lanczos tho.
Thanks for putting the labels on yours Rob. Interesting ringing on the sinc. That looks a bit over the top for a proper sinc tho. I think there might be a coding issue going on in that one. Sinc in a box window will ring a little but that seems a bit too much to be correct.

ok so here is your tiny image scaled up
A few more with that freebee Image Analyzer I referred to (quite the swiss army knife, really!), using the sample image, enlarged 800%
Wiener 4:

Two of the fractals (no idea what the parameters do just playing). I got the best results by going x2, x2, x2 rather than straight (the image names include the parameters):
resize_Temp x2 region=7 regul=0 x2 region=7 regul=0 x2 region=7 regul=0.png
resize_Temp x2 region=9 regul=0 x2 region=9 regul=0 x2 region=9 regul=0.png
And two more from Gimp - progressive resize, 800% in 20 steps:
gimp_resize_steps.png
and a gimp plugin "smart enlarge" using resyntherizer(?) I enlarged 2x 2x 2x. The first was OK, but after that it certainly added detail, but bolloxed up the image:

And for your viewing pleasure, the gimp resynth plugin going the full 800% in one shot Not a good resize, but an interesting 70's acid trip none the less:

And here is the best I could do with some playing.
This was done with Image Analyzer fractal resize x 2 then a wiener resize x2, followed by a fractal resize x2. Pulled into gimp and added film grain.
