- updated to 6.6.4-8:
* Automatically set the quantum depth to 16 for HDRI.
* IPTC profile not always wrapped properly inside an 8BIM profile.
* TIFF tile geometry must be divisible by 16.
* Rename of SincPolynomial to SincFast for easier user understanding.
Ditto for LanczosChebyshev to LanzcosFast.
* Switch default resize filters to using the faster SincPolynomial
filter by default internally. However 'Sinc' will still use the
Trigonometric function, and can be used to assign the trig version
of Sinc() to filters using the filter expert options.
* The default filter for 'distort' was found to be a very blurry inaccurate
filter function. It was removed and replaced with a correct Gaussian
filter (as used by resize)
* Added a switch so that "-interpolate filter" will force the use of
a cylindrical filter for ALL pixels in distorted images. That is you can
use that switch to use a cylindrical filter even for images that are
being enlarged by the distortion. However EWA is still currently using
a fixed 2.0 sampling radius. This switch complements the use of "-filter
point" which turns off EWA filters in favor of interpolation for all
pixels in a distorted image. BOTH switches should not be used together.
* A bug in the support radius of the EWA resampling function was found,
now that correctly defined resize filters are being used. Suddenly Normal
Gaussian distortions are not so blurry, and tests with distortions of
the 'Rings' image show extremely good and clear results, with only minimal
blurring. The filter 'blur' expert option can be used to adjust this
further.
* Don't negate the geometry offset for the -extent option.
* The RGBO format is now listed as a supported format.
* Added the Nicolas Robidoux and Chantal Racette Lanczos resize filter
function as "LanczosChebyshev" as faster alternative to Lanczos.
