Free zinc software for linux

Zinc is a Tk widget developed with Perl/Tk, Tcl/Tk and Python/Tk bindings. Zinc widgets are very similar to Tk canvases in that they support structured graphics.

Graphical items can be manipulated, and bindings can be associated with them to implement interaction behaviors. But unlike the canvas, zinc can structure the items in a hierarchy, and has support for affine 2D transforms.

Clipping can be set for sub-trees of the item hierarchy and the item set is quite more powerful, including field-specific items for Air Traffic systems.

Zinc is fast enough to allow the implementation of 2k2k radar displays with smooth animations. It is structured enough to allow the implementation of direct manipulation desktop GUIs.

SVG::SVG2zinc is a Perl module to display or convert svg files in scripts, classes, images...

SYNOPSIS

use SVG::SVG2zinc;

&SVG::SVG2zinc::parsefile(file.svg, Backend,file.svg,
-out => outfile,
-verbose => $verbose,
-namespace => 0|1,
-prefix => string,
);

# to generate a Perl script:
&SVG::SVG2zinc::parsefile(file.svg,PerlScript,
-out => file.pl);

# to generate a Perl Class:
&SVG::SVG2zinc::parsefile(file.svg,PerlClass,
-out => Class.pm);

# to display a svgfile:
&SVG::SVG2zinc::parsefile(file.svg, Display);

#To convert a svgfile in png/jpeg file:
&SVG::SVG2zinc::parsefile(file.svg, Image,
-out => file.jpg);

# to generate a Tcl script:
&SVG::SVG2zinc::parsefile(file.svg,TclScript,
-out => file.tcl);

Depending on the used Backend, &SVG::SVG2zinc::parsefile either generates a Perl Class, Perl script, Tcl Script, bitmap images or displays SVG files inside a Tk::Zinc widget.
SVG::SVG2zinc could be extended to generate Python scripts and/or classes, or other files, just by sub-classing SVG::SVG2zinc::Backend(3pm)

==head1 HOW IT WORKS

This converter creates some TkZinc items associated to most SVG tags. For example, < SVG > or < G > tags are transformed in TkZinc groups. are converted in TkZinc curves.... many more to come...

==head2 TkZinc items tags

Every TkZinc item created by the parser get one or more tags. If the corresponding svg tag has an Id, this Id will be used as a tag, after some cleaning due to TkZinc limitation on tag values (no dot, star, etc...). If the corresponding svg tag has no Id, the parser add a tag of the following form : __< itemtype >__< integer >. If the parser is provided a -prefix option, the prefix is prepended to the tag: __< itemtype >__< integer >

The TkZinc group associated to the top tag has the following tag svg_top, as well as width=integer heigth=integer tags if width and height are defined in the top < SVG > tag. These tags can be used to find the group and to get its desired width and height.

==head2 RunTime code

There is currently on new Tk::Zinc method needed when executing perl code generated. This perl Tk::Zinc::adaptViewport function should be translated and included or imported in any script generated in an other scripting language (eg. Tcl or Python).

CAD::Drawing::GUI::View are 2D graphics for CAD built on Tk::Zinc.

This module provides methods to turn a CAD::Drawing object into a Zinc canvas.

Overridden Methods

These make me behave like a Tk widget.

ClassInit

$view->ClassInit();

InitObject

$view->InitObject();

configure

$view->configure(%args);

args_filter

Filters configure arguments and adds non-tk args to our private data.

%args = $view->args_filter(%args);
