Statistics on PAW home page access: an SVG example


This plot has been produced with the new PAW/HIGZ SVG driver. SVG is a language for describing two-dimensional graphics in XML. SVG allows for three types of graphic objects: vector graphic shapes, images and text. Graphical objects can be grouped, styled, transformed and composed into previously rendered objects. The feature set includes nested transformations, clipping paths, alpha masks, filter effects and template objects. SVG drawings can be interactive and dynamic. Animations can be defined and triggered either declaratively or via scripting.

The way to access SVG in PAW (in my private version only) is the following:

PAW > Fortan/File 66 paw.svg
PAW > Metafile 66 -779
PAW > Exec macro
PAW > Close 66
It is best viewed with Internet Explorer and you need the Adobe SVG Viewer. To zoom using the Adobe SVG Viewer, position the mouse over the area you want to zoom and click the right button. To define the zoom area, use Control+drag to mark the boundaries of the zoom area. To pan, use Alt+drag. By clicking with the right mouse button on the SVG graphics you will get a pop-up menu giving other ways to interact with the image.

SVG files can be used directly in compressed mode to minimize the time transfer over the network. Compressed SVG files should be created using gzip on a normal ASCII SVG file and should then be renamed using the file extension .svgz. The following table gives the different sizes (given by ls -l) of this plot in various formats:

PostScript:                 20102
GIF:                        14519
ASCII SVG:                  33617
Compressed SVG (gzip -9):    3380
The plot presented here is in Compressed SVG format.
