Phoenix -PHoto Editor for uNIX

* Phoenix is a 24-bit bitmap painting program for X Window
System/Motif. The internal image is always 24-bit, no matter what kind
of display is used. The image is converted to a X-displayable form
(quantized and dithered in real-time if necessary) according to each
display type. The current version supports 1-, 4- and 8-bit gray scale
displays and 8-, 12- and 24-bit color displays. All visual classes
will be supported (most are already).

* With Phoenix you can edit pictures with all of the tools normally
found in a bitmap painting program (points, freehand, adjustable
airbrush, line, polyline, rectangle, ellipse and circle). You can also
select masks or areas with rectangle, ellipse, polygon, lasso or color
range selection tools. The selected area can then be used as a mask,
as a brush for all the drawing tools or as a fill pattern. There are
also many predefined adjustable brushes and fill patterns to choose
from. Drawing can take place only inside the mask, outside it or both.
Drawing modes include replace (= the 'normal' mode), add and subtract
modes, which are useful in creating different special effects.

* With filters you can change the appearance of the whole image or
just the selected area. Filters include invert, darken, brighten,
soften, sharpen, user-defined 5x5 matrix, RGB-adjust, HSV-adjust and
add noise. You can also transform the whole image using standard
transformations like: resize, h-flip, v-flip and rotate (by an
arbitrary angle).

* Phoenix allows you to combine different drawing tools, modes, user
blocks, patterns and filters in any way you want, making it the most
versatile painting program available.

* Phoenix allows you to edit multiple images simultaneously. You can
also have many views (in different scales) to a single image. The only
limit to image size and number of images is the available memory on
your computer.

* Supported image types are pbmplus formats (pbm, pgm, ppm). Phoenix
can be configured to use an io-filter to convert image to these
formats (eg. if you have pbmplus package installed in your system you
can virtually load any kind of file with Phoenix). The io-filter to be
used for loading and saving is decided by the file name extension.
(eg. with '.gif' you could use 'giftoppm' for loading). All of this is
totally transparent to the user.

* The Phoenix package includes complete C source code, an easy-to-read
60-page user manual and the system manual for Phoenix developers (in
PostScript and FrameMaker format). You can get it via anonymous ftp
from nic.funet.fi:pub/graphics/packages/phoenix.

* Phoenix is freeware. This means anyone can copy and use it freely
for any non-commercial purpose. Users are encouraged to enhance and
add their own features to Phoenix.

* Phoenix was made in the Helsinki University of Technology (Finland)
for a summer course by three students; Petri Kuittinen, Hannu Mallat
and Vesa Tormanen. Phoenix was written with ANSI C using the gcc
compiler. We have made it with X11R5 and Motif1.2, but it will
probably work with older versions as well.
 
* This is an alpha release of Phoenix. It is intended for people who
wish to take part in developing the final release by porting phoenix
to different UNIX platforms and different versions of X and Motif and
sending us their solutions. After a while (and hopefully a lot of
diffs to our sources) we will combine these to make a final version.
