GNUMail (Version (nil))
P. R. I. C. E. 0.8.2
I released a new version of price, 0.8.2, today.
The crash bug affected only GNUstep, but it was already present in
0.8.1, so this is a suggested upgrade.
What is PRICE?
It stands for Precision Raster Image Convolution Engine and is an
application that is capable of filtering and processing images. It is
available on both GNUstep (this linux, netbsd, freebsd, openbsd,
solaris) and Macosx (tested from 10.1 Puma and up). It is
multi-document based and can open all standard images supported by
gnustep (tiff, png, jpg to cite some). It is capable of doing standard
operation like crop&scale or brightness&contrast as well as more
advanced operations with frequency-based filters or median filters or
customizeable edge tracing.
Where to find it?
where you will find also some online documentation which you will
probably need to understand better how to use the program.
PRICE is GPL'd and each filter is a separate class with well-defined
interfaces so I encourage the reuse of them in other applications.
What are the news?
- selectable method for greyscale conversion (rgb average and
luminance of YCrCb)
- image inversion for both color and greyscale images
- in the GNUstep version an interface was corrected since it was
corrupted and caused crashes
and since 0.8.0:
- GNUstep and Macos-X share now the same code source! This not only
means that the old Sourceforge file packages are obsolete (if you were
tracking them) but also the cvs modules are now merged under the
and many small and big bug-fixes of course.
There are of course several limitations and shortcomings of which I am
aware, but some of them aren't there just because of lack of time,
others because of lack of knowledge. I'm open for discussion and help.
I hope you enjoy it however
