2010-09-28 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmail...># Chantal Racette double checked the bounding parallelogram computation in resample.c (and I tightened the comments).2010-09-28 6.6.4-8 Cristy <quetzlzacatenango@image...># Temporary files not always deleted (reference http://www.imagemagick.org/discourse-server/viewtopic.php?f=2&t=15960).2010-09-27 6.6.4-8 Nicolas Robidoux <nicolas.robidoux@gmail...># Simplified the ClampUpAxes code, the use of its outputs, its comments, and credited Craig DeForest for the "clamp singular values" idea.# No reason to have "insane" precision Sinc in resize.c: Use the 1.2e-12 max. abs. relative error version for Q64 as well as Q32.2010-09-27 6.6.4-8 Anthony Thyssen <A.Thyssen@griffith...># Replace the blurry "High Quality EWA" technique with a 'Clamped EWA' for Distort Resampling. This makes -distort a whole lot nicer and allows for the use of better cylindrical filters.# Bug fix for -filter point distorts (occasional generating black pixels)
2010-10-03 6.6.4-9 Cristy <quetzlzacatenango@image...># Fix memory assertion with --enable-embeddable (reference http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17201).# Don't permit access to pixels when pinging an image (reference http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=17194).2010-10-02 6.6.4-9 Anthony Thyssen <A.Thyssen@griffith...># Added sqrt(2) bluring default for Gaussian Filter if used as a Cylindrical EWA filter. This resulted in the last aliasing issue that was present in tests for Gaussian EWA resampling. However it is still a very blury filter for default use in EWA.# Adjusted Variable Mapping Blur Composition so user arguments actual relate properly to the sigma of the blur for a maximum mapping value.# Fix horizon anti-alising for output scaled perspective distortions.# 'Bessel' filter is nor offically and more accuritally named 'Jinc' however 'Bessel' while not visible as a filter option can still be used as an internal alias for 'Jinc'.
2010-10-08 6.6.4-10 Jerry Gay <jerry.gay@gmail..># Autodetect file type support in Makefile.PL to prevent test failures2010-10-05 6.6.4-10 Anthony Thyssen <A.Thyssen@griffith...># Added new filter 'Lanczos2D' a 2-lobe Lanczos as defined by Andreas Gustafsson in his thesis "Interactive Image Warping" (page 24) http://www.gson.org/thesis/warping-thesis.pdf# Added filter "Robidoux" whcih is a 'negativally' blurred version of the "Lanczos2D" filter specifically designed to be less 'blurry' for horizontal and vertical lines in no-op distortions. It is now the default filter (if none specified) for EWA resampling.2010-10-05 6.6.4-10 Cristy <quetzlzacatenango@image...># Add support for "pattern:vertical2" and "pattern:horizontal2".# Add support for "pattern:vertical3" and "pattern:horizontal3".# Properly handle PSD layers with negative offsets.
