PRICE 1.3.0

Finally a new release of PRICE!

Get it here: https://sourceforge.net/projects/price/files/1.3.0/

This version improve Mac support quite a bit, Apple made several changes since 10.6 which caused malfunctions and weird symptoms (and which fix occasional stuff on 10.4 too). Both PowerPC and x86 work fine!

Many bug fixes, memory issues, bug in filters fixed.

• Curves can now be manipulated with handles
• Edge/tracing ignores the alpha channel
• Preview supports scaling
• Support by on-load conversion of alpha-first images
• Greyscale and Inversion support 16bit images, highly experimental! The current approach looks unpractical to extend to all filters since the code-path needs to be doubled though.

Custom Edge Tracer, PRICE on GNUstep

Curves Editing, PRICE on MacOS

PRICE 1.2.0

After 10 Years with PRICE a Christmas Anniversary release! 1.2.0 is out!

This new version sports JPEG saving along with TIFF! Thus PRICE rgisters itself as editor both for TIFF and JPEG files. Compression factor is of course user selectable.

Along with many bugfixes, the Curves function is now improved in usability: the transformed histogram is drawn specular on top instead of right. Furthermore bug fixes should make the display more reliable and faster.

Of course, for GNUstep and Macintosh.

PRICE 1.1.0

PRICE 1.1.0 is out!

It has been a long hiatus, I essentially skipped a release and made two in one. What's new?

Curves: this was a lot of work (and will need more). Smooth way to correct highlights and shadows with an S-curve. Source and resulting histograms are displayed.

Bilinear filtering: scaling will now look better!

Minor tweaks to the interface, like the filters that on cancel while previewing or on GNUstep the convolve matrix reacting on end editing.

Furthermore a plethora of bug fixes and portability enhancements.

Get it here from SourceForce, in form of sources for all platforms (GNUstep or Cocoa) or as Macintosh binary.

It has been 10 years I've been working on PRICE. This is kind of an anniversary release. It has been a long time and it has been fun and I hope it will continue! But it is an amazing long time. There have been ups and downs, and some melancholy creeps in! I think I will blog more about some past and future ideas about GNUstep.

bilinear filtering

Finally PRICE got proper Bilinear filtering.

This was surely long due! The previous linear h+v filter was little more than a quick hack.

Bilinear filtering is quick, good and quite sharp and works well with scaling between the 50% and the 150% range. It is quite good when downscaling while upscaling beyond a certain range surely has better algorithms.

LaternaMagica and its export tool with automatic constraining will benefit from this new filter too.

PRICE 0.8.3

Finally, after several months, PRICE 0.8.3 is out. Mainly it is a bug-fix and performance improvement release compared to 0.8.2. Chasing a memory leak which appeared only on GNUstep, Gregory found a piece of inefficient code which let to morememory usage and slower performance, but no solution to the hideous leak. Fred fixed it recently in GNUstep, this means that the PRICE code was good and that it was ready for release and that if you don't want to leak, you need the next gnustep-gui release.
Another issue is the License, the past GNUstep release was GPLv3 and this caused incompatibility to GPLv2; under Debian's maintainer suggestion I added an exception, but this is an unsatisfactory solution, thus I decided to relicense PRICE with GPLv2 and the "and later" option. Now GNUstep got relicensed back due to all the trouble; but my decision stands, also to avoid any more trouble in the future.
