Produces a portable anymap as output. The type of the output file depends on the input file - if it's black & white, a pbm file is written, else if it's grayscale a pgm file, else a ppm file. The program tells you which type it is writing. Hope that helps!

From: rubini@unipv.it (Alessandro Rubini) Subject: [ANNOUNCE] Pacco-0.6: image processing under tcl-Tk Date: 30 Mar 94 10:49:29 GMT Version 0.6 of Pacco (Pavia Active-Component Compound Objects) is available by ftp at iride.unipv.it, in the directory /pub/Pacco The files (and their size) are: README-0.6 the "read me" (12kB) pacco-0.6.tz tarred & gzipped distribution (550kB) pacco-docs-0.6.tz the ps docs included in the distribution (100kB) ===== What's Pacco? ====== Pacco extends tcl (and tk) to allow handling of binary object. The long term goal is to provide a way to manage objects in a distributed environment. Currently the main stress is on image processing and interactive i.p. tools, but the approach is object-type independent as far as kernel functions are concerned. The package is still considered a beta release. ===== What's tcl-tk? (this is a crosspost) ===== Tcl is an extensible, interpreted language. Tk is an extension to Tcl which provides the programmer with an interface to the X11 windowing system. Pacco adds image display capabilities to the tk widget set. Tcl-7.3 and Tk-3.6 are available at harbor.ecn.purdue.edu:/pub/tcl/distrib They are available at our site, too, just in case... ===== What's new? ======== Lots and lots of features ... excerpts from the README: - a ps manual of 25-30 pages; - dynamic loading of unknown classes/actions; - a network daemon (paccod) is available; - actions may be coded in tcl, too; - Img_cplxsobel: an action computing the gradient with sobel kernels; - image thresholding, rotation, transposition; - there is a pacmap canvas item and images can be displayed into canvases; the postscript code generated by the items uses the current colormap, therefore changes made with clut/menu menus are reflected into the postscript code. ===== What's needed? ===== System requirements to install Pacco are as follows: - a unix workstation or PC with shared memory support - an ANSI C compiler (gcc preferred) - gmake (we used 3.63, maybe other make's will do, but you never know...) - a tcl library (7.x are allowed) - a tk library, only needed to run pacmap (either 3.3 or later) Pacco has only been tested on the following architectures: sparcstation-2 (SunOS 4.1.2) apollo 9000-720 (hp-ux 8.07 / 9.01) pc-clone 386 (Linux 1.0) Anyway, portability is our majour concern and porting to other platforms should be easy. ===== Questions? ========= Don't wait! mail to rubini@ipvvis.unipv.it (Alessandro Rubini) or alberto@ipvvis.unipv.it (Alberto Biancardi) -- ========================= alessandro rubini rubini@ipvvis.unipv.it =========================
