Ok, download the wikimedia SVG and open it with a text editor. If you look for "Ulster, NY" you will see it enclosed in a path node. The contents of the "d" attribute is what you need to parse/extract to pass as parameter to RTSVGPath>>path: <path style="font-size:12px;fill:#d0d0d0;fill-opacity:1;fill-rule:nonzero;stroke:#000000;stroke-opacity:1;stroke-width:0.1;stroke-miterlimit:4;stroke-dasharray:none;stroke-linecap:butt;marker-start:none;stroke-linejoin:bevel" d="M 501.96598,97.8 L 502.15198,100.009 L 502.68298,101.739 L 502.88598,102.153 L 503.20498,104.028 L 502.29498,104.366 L 501.61098,104.502 L 501.02498,104.483 L 500.32998,104.231 L 499.33398,104.921 L 498.91498,104.299 L 497.86898,103.844 L 496.94598,103.415 L 497.13498,102.933 L 497.50398,102.086 L 497.69798,101.505 L 495.56698,100.824 L 494.24598,100.423 L 496.85998,97.791 L 498.36098,98.174 L 499.08798,98.084 L 500.56998,97.894 L 500.65098,96.89 L 501.06998,96.754 L 501.99798,97.146 L 501.96598,97.8" id="36111" inkscape:label="Ulster, NY" /> I have tried using the Roassal2 from the Configuration Browser in Pharo 3.0.

Hi Hernan, Thanks for your answer. I got an error which says "Error: Reading a number failed: a digit between 0 and 9 expected" and "element" of your example is selected. I think that I'm not understanding well how to connect the downloaded file (in fact I have not downloaded anything) to the part where you render the svg and I don't see anything in your example which links them. Whats the thing I'm missing? Thanks for your help. Hopefully, tomorrow we can show maps for new territories in Roassal.

Re: [Pharo-users] RTMultiCompositeShape + Bitmap

by rosariosm

Hi Alex! I have updated trachel but it still doesnt work. I think i found another bug. Look at this new example: | element label bitmap composite text | text := (WriteStream on: ' ') nextPutAll: 'string1'; nextPut: Character cr; nextPutAll: 'string2'; contents. label := RTLabel new text: text. bitmap := RTBitmap new form: (Form dotOfSize: 10). composite := (RTMultiCompositeShape with: bitmap with: label) vertical. element := RTElement new addShape: composite. RTLabel in trachel becomes a TRCompositeShape (because the text has two lines) and a TRCompositeShape doesnt understand #extent.

How do I

by Friedrich Dominicus

get the red color from the editor if aa methods gets really long. Eg I have an initialization of a dictionary with 50 or so elements and have put them into one method of course it's getting very red. Anyway it's just something like this add: Element add: anotherElement .... So no program logic at all just one element added after the other. I found I can still lint with a pragma, but still the editor is "red" That really gets on my nerves. So what can I do to stop this "reddening"? Regards Friedrich
