SVG PLOT CHECKING/DEVELOPMENT¶

svgplot-get: pull the SVG from the webapp
svgplot-eta: demo nofont SVG for single char of form produced by dvisvgm

CONVERT PLOT SVG TO PDF¶

pycairo¶

No path support yet ..

http://cairosvg.org/svg_support/#paths

inkscape¶

TRACING PLOT SOURCES¶

remote access to private servers¶

Open SSH socks proxy tunnels:

simon:~ blyth$ ssh -fND localhost:8080 K
simon:~ blyth$ ssh -fND localhost:9090 K

For details, and browser/curl config to use the proxy see env:base/ssh

cocoon sitemap¶

Directs a URL regexp to cocoon XML generator plot.xq

heprez:source:hfag/mods/webapp/hfagc/sitemap.xmap.template

851              <map:match type="regexp" pattern="^(0)(\d)(\d)(\d)(\d)/plot/(svg|xml)$">
852                   <map:generate src="plot.xq" type="xquery" label="sauce"  >

plot.xq generator XQuery¶

heprez:source:hfag/mods/webapp/hfagc/plot.xq

Request parameter handling, fork on individual or combined plot, hand over to make-plot.xqm

make-plot.xqm XQuery lib¶

heprez:source:hfag/mods/webapp/hfagc/xquery/make-plot.xqm

Mostly cache control, the nitty gritty handed down to rezs.xqm

rezs:qtset2svg SVG generation¶

heprez:source:hfag/mods/webapp/hfagc/xquery/rezs.xqm
- rezs:qtset2svg
- rezs:present-vals
- rezs:qt2svglabel rezs:qt2svgsabel

rezs:qt2svglabel¶

Label is returned asis from /db/hfagc_system/qtag2svgs.xml

After opening the tunnel

http://130.87.106.59:9090/servlet/db/hfagc_system/

0039 declare variable $rezs:qtag2svgs_index  as xs:string { "/db/hfagc_system/qtag2svgs.xml" } ;
....
1618 (:
1619       this is used in individual and combi plot SVGs
1620 :)
1621 declare function rezs:qt2svglabel( $qt as xs:string , $opt as xs:string ) as element() {
1622
1623     let $label := if( doc-available($rezs:qtag2svgs_index) ) then
1624                      doc($rezs:qtag2svgs_index)//qtag[@value=$qt]/svgs/label/*
1625                   else
1626                      <text x="0" y="0"> no label[{$qt}] </text>

Check the index¶

Use the interactive XQuery form in the context of hfagc_system collection

http://130.87.106.59:9090/xmldb/db/hfagc_system/

To grab the indexed SVG labels:

doc("qtag2svgs.xml")//qtag[@value='BR:-521:-321,221,443']
doc("qtag2svgs.xml")//qtag[@value='BR:-521:-321,221,443']/svgs/label/*[1]     (: grabs the svg:g elem :)
doc("qtag2svgs.xml")//qtag[@value='BR:-521:-321,221,443']/svgs/sabel/*[1]     (: grabs the svg:g elem :)

Observations on the SVG:

absolute path data for each bezier curved glyph has x y ranges in ballpark -9 to +9, maybe ordinary character point size units
crazy large +ve y (down) translation is apparent

Centering the label¶

Taking /Users/heprez/data/data/images/qtags/svg_nofonts/slBR_-511_-311+83xoBR_-521_-321+83.svg:

<svg height='18.3592pt' version='1.1' viewBox='57.6088 53.7982 44.272 18.3592' width='44.272pt' xmlns='http://www.w3.org/2000/svg' xmlns:xlink='http://www.w3.org/1999/xlink'>
<defs>
    ...
</defs>
<g id='centering' transform='translate(-57.6088,-53.7982)'>
<g id='page1' transform='matrix(0.996264 0 0 0.996264 0 0)'>
   <path id='bbox' d="M57.6088 53.7982 h 44.272 v 18.3592 h -44.272 z" fill="none" stroke="blue" />
   <use x='58.8804' xlink:href='#g0-89' y='60.69'/>
   <use x='65.6958' xlink:href='#g1-40' y='60.69'/>
   ...
</g>
</g>
</svg>

The centering group and bbox path are based on the viewBox numbers. Instead of crazy gridification, applying such transforms at svgsmry stage can avoid the kludge constant offset.

Check the summary¶

Use the interactive XQuery form in the context of hfagc_system collection

http://130.87.106.59:9090/xmldb/db/hfagc_system/

declare namespace svg="http://www.w3.org/2000/svg" ;
doc("svg-summary.xml")//svg:g[@id='slBR_-521_-321+221+443']

The big transforms hail from back in during summary creation (set by the gridification done in summary creation):

<svg:g exist:id ="1540" exist:source ="/db/hfagc_system/svg-summary.xml" id ="slBR_-521_-321+221+443" transform ="translate(154.963,6734.518)" >
  <svg:defs >
     <svg:path d ="M5.7 -3.324C5.76 -3.564 5....

Kludge with fixed transform modifying query¶

http://130.87.106.59:9090/xmldb/db/hfagc_system/

Grab the svg:g content and construct new svg:g without the transform attribute:

declare namespace svg="http://www.w3.org/2000/svg" ;

let $qt := 'BR:-521:-321,221,443'
let $g := doc("qtag2svgs.xml")//qtag[@value=$qt]/svgs/sabel/svg:g[1]
return
       <svg:g>
           {
              attribute id {$g/@id}
              ,
              $g/*
           }
       </svg:g>

Kludge fixed offset¶

1620 declare function rezs:qt2svglabel( $qt as xs:string , $opt as xs:string ) as element() {
1621     let $g := doc($rezs:qtag2svgs_index)//qtag[@value=$qt]/svgs/label/svg:g[1]
1622     let $transform := "translate(0,-66)"
1623     return
1624            <svg:g>
1625            {
1626               attribute id {$g/@id}
1627               ,
1628               attribute transform {$transform}
1629               ,
1630               $g/*
1631            }
1632            </svg:g>
1633 };
1634
1635 declare function rezs:qt2svgsabel( $qt as xs:string , $opt as xs:string ) as element() {
1636     let $g := doc($rezs:qtag2svgs_index)//qtag[@value=$qt]/svgs/sabel/svg:g[1]
1637     let $transform := "translate(0,-66)"
1638     return
1639            <svg:g>
1640            {
1641               attribute id {$g/@id}
1642               ,
1643               attribute transform {$transform}
1644               ,
1645               $g/*
1646            }
1647            </svg:g>
1648 };
1649

Check old function¶

import module namespace rezs = "http://hfag.phys.ntu.edu.tw/hfagc/rezs" at "webapp/hfagc/xquery/rezs.xqm" ;
let $qt := 'BR:-521:-321,221,443'
return
      rezs:qt2svgsabel( $qt, "" )

Add new function¶

heprez:r908

propagate:

b2mc:h heprez$ exist-up webapp/hfagc trial      # observe non-propagated D0 addition as well as the modified label funcs

Testing on dynamic plot URL, shows the label positions are now in the ball park

Grab from afar:

simon:k blyth$ curl -s --socks5 localhost:9090 http://130.87.106.59:9090/hfagc/01114/plot/svg -o 01114.svg
