== Introduction ==
|
|
|
|
This page demonstrates the results of resampling different images using various resize filters.
|
|
|
|
Images used for the test:
|
|
|
|
|| [http://nvidia-texture-tools.googlecode.com/svn/wiki/imgs/test1.png] || [http://nvidia-texture-tools.googlecode.com/svn/wiki/imgs/test3.jpg] || [http://nvidia-texture-tools.googlecode.com/svn/wiki/imgs/test5.jpg] ||
|
|
|
|
The width of the filters are:
|
|
|
|
|| *Box* || *Triangle* || *Quadratic* || *Lanczos* || *Kaiser* ||
|
|
|| 0.5 || 1.0 || 1.5 || 3.0 || 5.0 ||
|
|
|
|
The parameters used for the Kaiser filter are:
|
|
|
|
{{{
|
|
alpha = 4
|
|
stretch = 1
|
|
}}}
|
|
|
|
== Test 1 ==
|
|
|
|
Downsampling without gamma correction.
