/* Some info on basic items SVG format, used here:
|
|
* The root element of all SVG files is the <svg> element.
|
|
*
|
|
* The <g> element is used to group SVG shapes together.
|
|
* Once grouped you can transform the whole group of shapes as if it was a single shape.
|
|
* This is an advantage compared to a nested <svg> element
|
|
* which cannot be the target of transformation by itself.
|
|
*
|
|
* The <rect> element represents a rectangle.
|
|
* Using this element you can draw rectangles of various width, height,
|
|
* with different stroke (outline) and fill colors, with sharp or rounded corners etc.
|
|
*
|
|
* <svg xmlns="http://www.w3.org/2000/svg"
|
|
* xmlns:xlink="http://www.w3.org/1999/xlink">
|
|
*
|
|
* <rect x="10" y="10" height="100" width="100"
|
|
* style="stroke:#006600; fill: #00cc00"/>
|
|
*
|
|
* </svg>
|
|
*
|
|
* The <circle> element is used to draw circles.
|
|
* <circle cx="40" cy="40" r="24" style="stroke:#006600; fill:#00cc00"/>
|
|
*
|
|
* The <ellipse> element is used to draw ellipses.
|
|
* An ellipse is a circle that does not have equal height and width.
|
|
* Its radius in the x and y directions are different, in other words.
|
|
* <ellipse cx="40" cy="40" rx="30" ry="15"
|
|
* style="stroke:#006600; fill:#00cc00"/>
|
|
*
|
|
* The <line> element is used to draw lines.
|
|
*
|
|
* <line x1="0" y1="10" x2="0" y2="100" style="stroke:#006600;"/>
|
|
* <line x1="10" y1="10" x2="100" y2="100" style="stroke:#006600;"/>
|
|
*
|
|
* The <polyline> element is used to draw multiple connected lines
|
|
* Here is a simple example:
|
|
*
|
|
* <polyline points="0,0 30,0 15,30" style="stroke:#006600;"/>
|
|
*
|
|
* The <polygon> element is used to draw with multiple (3 or more) sides / edges.
|
|
* Here is a simple example:
|
|
*
|
|
* <polygon points="0,0 50,0 25,50" style="stroke:#660000; fill:#cc3333;"/>
|
|
*
|
|
* The <path> element is used to draw advanced shapes combined from lines and arcs,
|
|
* with or without fill.
|
|
* It is probably the most advanced and versatile SVG shape of them all.
|
|
* It is probably also the hardest element to master.
|
|
* <path d="M50,50
|
|
* A30,30 0 0,1 35,20
|
|
* L100,100
|
|
* M110,110
|
|
* L100,0"
|
|
* style="stroke:#660000; fill:none;"/>
|
|
*
|
|
* Draw an elliptic arc: it is one of basic path command:
|
|
* <path d="M(startx,starty) A(radiusx,radiusy)
|
|
* rotation-axe-x
|
|
* flag_arc_large,flag_sweep endx,endy">
|
|
* flag_arc_large: 0 = small arc > 180 deg, 1 = large arc > 180 deg
|
|
* flag_sweep : 0 = CCW, 1 = CW
|
|
* The center of ellipse is automatically calculated.
