(It has been updated even more since this):
Main Features in 8.2:
* A greatly wrangled plugin folder and browser, also adding support for tooltips for plugins.
* GPU support. An enhanced 3D Designer is the first to make use of new GPU support.
* GUI improvements and cosmetic changes for Windows 8.
Updated plugins
In 8.2, we’re adopting an “everything down to the raw loader” philosify, meaning we’re dusting off a lot of old plugins, internalizing some, refreshing the GUI of ones that haven’t been udpated to the newer look, and just generally making a lot of little updates and polishes.
* There’s a new forcefield type that can be used to create gravity/explosion fields.
* The foliage tool now also supports forcefields.
* Cosmetic changes to better support the flat look of Windows 8.
* Interface tweaks for more usability.
* Fixed an error in saving pigment profiles.
* Saving Avi’s now remembers the last filename during a session, and there’s an updated panel.
* Grid and Artist guide settings are now saved and restored.
* A couple of fixes on the animated brush timeline.
* The plugin panel now supports tooltips for each plugin.
* Changes to the plugin panel now also allow date and size of plugin creation, author and information about the plugin, plus pattern matching and opening the Explorer.
* The plugin panel and lua browser are now more functionally and visually similar.
* Fixed ‘numeric select’ not activating from the alpha panel.
* fixed “store brush as image” feature to not crash if a brush is not defined.
* GUI_Server, hence lua scripts with a GUI, now use the new visual style.
* The Brush/Transparency/Transparency tool now uses the new visual style.
* The brush keyframer now uses the new visual style.
* Frame Painter now uses the new visual style.
* Fixed some layout problems with the print panel.
* fixed crash if entering numbers above 255 in gradient panel.
* The tritone filter now supports rendering to an animation. The “multicolor” animated lua script version of it has thus been removed from the filters/animated cate gory.
* There’s a new 1 bit per channel filter under Color/1 bit dither… Possible uses: preparing a graphic for pixel for pixel output to a printing device maybe.
* The Mod dog (music) player plugin is updated to run under 64 bit Windows. Rock on!
* A number of plugins have been updated. For example, the RYB mixer plugin now operates more smoothly.
* The installer no longer automatically runs the program after installation, for technical reasons. It should be run from the start menu.
* The “Undo buffer to animation” feature was leaving out 1 undo step. fixed.
* The tool panel is now adjusted on startup to always be on the right side of the sidebar if both are located together on the left side of the main panel.
* Eliminated all lua script usage from main functions, replaced with internal code.
Some things renamed…
* “Unit calculator” on the image resample panel is renamed “Other units” to sound less mathy.
* “Store image” is renamed “Store image copy” to be more clear.
* The brush key menu is renamed “Transparency” and reorganized. Most of the items have been internalized.
* added Dogwaffle.Dog_ColorToRGB(c, r, g, b) subroutine in the plugin interface.
It is not a function, but a subroutine. The return results are in r,g,b which is converted from the color value in c, such as “&HFF4422;”. This routine is added to support .net framework plugins that often have fuctions that accept colors in R,G,B values instead of packed format.
* Added the bmp image sequence to avi converter plugin to the misc utilities menu.
More internalized plugins…
* Red eye removal
* Scale_Alpha_pm.exe
* ExploreTempDir_pm.exe
* 8 bush keying plugins internalized.
* a number of quantizing (color reduction) plugins have been interalized.
* Load to stored
And more to come, so stay tuned.
PD Howler is a very unique software, at first it might be odd, but the more time is spent with it the more it grows on you and gives some really exceptional options that can be used to enhance your creations in a very interesting manner
