  2. What is SVG? Scalable Vector Graphics (SVG) is an open, industry-standard XML-based format for vector graphics developed by the W3C. • Scaleable – images maintain their quality when resized • Vector– images are defined by a sequence of instructions • XML so can be searched and indexed

  3. Basic shapes • rect[angle] • circle • ellipse • line • polyline • polygon • path • + text

  4. W3C SVG tutorial • https://www.w3schools.com/graphics/svg_intro.asp

  5. SVG can be embedded in HTML • https://www.w3schools.com/graphics/tryit.asp?filename=trysvg_polygon

  6. Creating SVGs • Simple SVGs are easy to code • Many graphics programs can produce SVGs – Inkscape, inkscape.org is open source • In some applications producing SVGs with placeholders may be a good answer

  7. Delphi and SVG • Various SVG libraries exist (not tried by me): • Delphi SVG : A$80 • Riversoft SVG: www.riversoftavg.com A$93 • SVG Magic: svgmagic.io A$140 • .. and others

  8. SVGs from scratch • Subset of SVG delivers what I need
