High Quality Zoom, provided by Photo-Lux
Displaying of the zoomed images on the screen
assumed that image will be resized (recalculated) in the memory of the
PC, and, after that, a resized copy of the image will be displayed on
the screen. In many cases a resized copy of the image can contain a lot
of distortions - to smooth the jagged edges and to reduce the noise artifacts
special filters should be used (smoothing or antialiasing technique).
A simple example can illustrate it:
|
Original Image.
|
Zoom 75%. A lot of jagged edges can
be easily found. Most of graphics software produces the same poor
zooming quality. |
High Quality Zoom 75% provided by
"PhotoLux" using Lanczos3 zoom
filter. |

There are 11 zoom filters available on "Photo-Lux" - Triangle,
Hermite, Bell, BSpline, Lanczos3, Mitchell, Nearest, Linear, Fastlinear,
Bilinear and Bicubic - this allows you to experiment with various filters
to choose the best quality. Lanczos3 filter can produce the best quality
in many cases but it working a bit slowly. Fastlinear filter working a
bit faster, but usually provides not too excellent results.
