|Imagener includes two levels of technology, each very effective
but very different in the way they go about the task of enlargement.
One level, found in our Enhanced and Professional products is similar
algorithmically to all of the enlargement products on the market.
This first level is implemented in the Imagener products in 3 out
of the total of 4 enlargement engines. Customers will recognize this
first level in the "Resample Methods" of the Imagener interface
in the drop-down box:
- Kneson Progressive
- Kneson Progressive++
All of these enlargement engines are effective on their own. As
mentioned in our resample methods newsletter (click
here) - you should use all enlargement engines depending on the
image content. Smaller images either in size or in resolution can
actually benefit from being enlarged with
one of the lower engines. Do not be afraid to experiment. You will
also find 3 lesser "enlargement engines" (if you can call
them that) in the drop-down box of Resample Methods listed as:
These methods are actually quite simple enlargement
algorithms developed over two decades ago, and are still the only
ones offered in the highest-end photo manipulation software products
like Adobe Photoshop® and Paint Shop Pro®. While these products are
excellent in what they do for digital images, they still have not
improved how they enlarge photos. The best enlargement algorithm
they can provide is Bicubic enlargement as we discussed on our
sister website, Photoenlargement.org.
Kneson Software recognized this shortcoming as far back as 1994 when
we began development on the Imagener line of enlargement technologies.
The "Kneson," "Kneson Progressive," and "Kneson Progressive++"
enlargement engines represent a vast improvement in the intelligence
used to zoom in on digital images. All of these enlargement engines
analyze pixels well removed from each targeted pixel, then estimate
how colors change
on the overall patterns of the particular image. This fills in
areas with pixels and colors based on much more image information
and enlarges photos to allow identification of image
content that was not possible before because more of the image
information is maintained in the enlargement.
