Wednesday

Midterm exam

• Subject area: SVG
• Type of exam: SVG file that you will have to complete according to instructions
• Open book. You may use both print texts and the Internet

Items that may be tested

• SVG embedding in HTML
• Graphic primitives (only the ones shown in my examples): rect, circle, ellipse, line, polyline, polygon and text)
  • Attributes you should know: position and size attributes, opacity, fill and stroke
• Grouping and reusing: Defining an "id", g and use
  • Make sure to master the transform attribute (scaling, rotation, and translation)
• Simple animation: animate
  • Attributes for animate: to, from, values, dur, begin, end, fill, attributeName, xlink:href, repeatCount

Not tested

• The "path" language. However, I may ask you to copy/paste a path from the online SVG-edit tool or change its style (e.g. the color).

Preparation:

Textbook chapters (you can ignore elements that did not present in class)

• http://commons.oreilly.com/wiki/index.php/SVG_Essentials/Basic_Shapes
• http://commons.oreilly.com/wiki/index.php/SVG_Essentials/Document_Structure
• http://commons.oreilly.com/wiki/index.php/SVG_Essentials/Animating_and_Scripting_SVG (Only the animate tag, in particular: ignore the scripting)

Important: If you want to print these textbook chapters, use the PDF that is in the Documents folder of the World Classroom. You are allowed to bring it to the exam ....

Wiki pages:

• Using SVG with HTML5 tutorial (mandatory reading, not covered in the text book)
• Static SVG tutorial (read SVG_Essentials/Basic_Shapes and Document_Structure if something is not clear)
• SVG/SMIL animation tutorial (only sections that concern the animate element, read VG_Essentials/Animating_and_Scripting_SVG if something is not clear)

Homework

None for this week. See homework 4, week4
