9.1 Introduction

SVG contains the following set of basic shape elements:

  • rectangles (including optional rounded corners), created with the‘rect’element,
  • circles, created with the‘circle’element,
  • ellipses, created with the‘ellipse’element,
  • straight lines, created with the‘line’element,
  • polylines, created with the‘polyline’element, and
  • polygons, created with the‘polygon’element.

Mathematically, these shape elements are equivalent to a‘path’element that would construct the same shape. The basic shapes may be stroked, filled and used as clip paths. All of the properties available for‘path’elements also apply to the basic shapes.

9.2 The‘rect’element

The‘rect’element defines a rectangle which is axis-aligned with the current user coordinate system. Rounded rectangles can be achieved by setting appropriate values for attributes‘rx’and‘ry’.

‘rect’
Categories:
Basic shape element, graphics element, shape element
Content model:
Any number of the following elements, in any order:
  • animation elements—‘animate’,‘animateColor’,‘animateMotion’,‘animateTransform’,‘set’
  • descriptive elements—‘desc’,‘metadata’,‘title’
Attributes:
  • conditional processing attributes—‘requiredFeatures’,‘requiredExtensions’,‘systemLanguage’
  • core attributes—‘id’,‘xml:base’,‘xml:lang’,‘xml:space’
  • graphical event attributes—‘onfocusin’,‘onfocusout’,‘onactivate’,‘onclick’,‘onmousedown’,‘onmouseup’,‘onmouseover’,‘onmousemove’,‘onmouseout’,‘onload’
  • presentation attributes—‘alignment-baseline’,‘baseline-shift’,‘clip’,‘clip-path’,‘clip-rule’,‘color’,‘color-interpolation’,‘color-interpolation-filters’,‘color-profile’,‘color-rendering’,‘cursor’,‘direction’,‘display’,‘dominant-baseline’,‘enable-background’,‘fill’,‘fill-opacity’,‘fill-rule’,‘filter’,‘flood-color’,‘flood-opacity’,‘font-family’,‘font-size’,‘font-size-adjust’,‘font-stretch’,‘font-style’,‘font-variant’,‘font-weight’,‘glyph-orientation-horizontal’,‘glyph-orientation-vertical’,‘image-rendering’,‘kerning’,‘letter-spacing’,‘lighting-color’,‘marker-end’,‘marker-mid’,‘marker-start’,‘mask’,‘opacity’,‘overflow’,‘pointer-events’,‘shape-rendering’,‘stop-color’,‘stop-opacity’,‘stroke’,‘stroke-dasharray’,‘stroke-dashoffset’,‘stroke-linecap’,‘stroke-linejoin’,‘stroke-miterlimit’,‘stroke-opacity’,‘stroke-width’,‘text-anchor’,‘text-decoration’,‘text-rendering’,‘unicode-bidi’,‘visibility’,‘word-spacing’,‘writing-mode’

Attribute definitions:

x= " "
The x-axis coordinate of the side of the rectangle which has the smaller x-axis coordinate value in the current user coordinate system.
If the attribute is not specified, the effect is as if a value of "0" were specified.
Animatable: yes.
y= " "
The y-axis coordinate of the side of the rectangle which has the smaller y-axis coordinate value in the current user coordinate system.
If the attribute is not specified, the effect is as if a value of "0" were specified.
Animatable: yes.
width= " "
The width of the rectangle.
A negative value is an error (see Error processing). A value of zero disables rendering of the element.
Animatable: yes.
height= " "
The height of the rectangle.
A negative value is an error (see Error processing). A value of zero disables rendering of the element.
Animatable: yes.
rx= " "
For rounded rectangles, the x-axis radius of the ellipse used to round off the corners of the rectangle.
A negative value is an error (see Error processing).
See the notes below about what happens if the attribute is not specified.
Animatable: yes.
ry= " "
For rounded rectangles, the y-axis radius of the ellipse used to round off the corners of the rectangle.
A negative value is an error (see Error processing).
See the notes below about what happens if the attribute is not specified.
Animatable: yes.

The values used for the x- and y-axis rounded corner radii are determined implicitly if the‘rx’or‘ry’attributes (or both) are not specified, or are specified but with invalid values. The values are also subject to clamping so that the lengths of the straight segments of the rectangle are never negative. The effective values for‘rx’and‘ry’are determined by following these steps in order:

  1. Letrxandrybe length values.
  2. If neither‘rx’nor‘ry’are properly specified, then set bothrxandryto 0. (This will result in square corners.)
  3. Otherwise, if a properly specified value is provided for‘rx’, but not for‘ry’, then set bothrxandryto the value of‘rx’.
  4. Otherwise, if a properly specified value is provided for‘ry’, but not for‘rx’, then set bothrxandryto the value of‘ry’.
  5. Otherwise, both‘rx’and‘ry’were specified properly. Setrxto the value of‘rx’andryto the value of‘ry’.
  6. Ifrxis greater than half of‘width’, then setrxto half of‘width’.
  7. Ifryis greater than half of‘height’, then setryto half of‘height’.
  8. The effective values of‘rx’and‘ry’arerxandry, respectively.

Mathematically, a‘rect’element can be mapped to an equivalent‘path’element as follows: (Note: all coordinate and length values are first converted into user space coordinates according to Units.)

  • perform an absolute moveto operation to location (x+rx,y), wherexis the value of the‘rect’element's‘x’attribute converted to user space,rxis the effective value of the‘rx’attribute converted to user space andyis the value of the‘y’attribute converted to user space
  • perform an absolute horizontal lineto operation to location (x+width-rx,y), wherewidthis the‘rect’element's‘width’attribute converted to user space
  • perform an absolute elliptical arc operation to coordinate (x+width,y+ry), where the effective values for the‘rx’and‘ry’attributes on the‘rect’element converted to user space are used as therxandryattributes on the elliptical arc command, respectively, thex-axis-rotationis set to zero, thelarge-arc-flagis set to zero, and thesweep-flagis set to one
  • perform a absolute verticallinetoto location (x+width,y+height-ry), whereheightis the‘rect’element's‘height’attribute converted to user space
  • perform an absolute elliptical arc operation to coordinate (x+width-rx,y+height)
  • perform an absolute horizontallinetoto location (x+rx,y+height)
  • perform an absolute elliptical arc operation to coordinate (x,y+height-ry)

Mathematically, a‘line’element can be mapped to an equivalent‘path’element as follows: (Note: all coordinate and length values are first converted into user space coordinates according to Units.)

  • perform an absolute moveto operation to absolute location (x1,y1), wherex1andy1are the values of the‘line’element's‘x1’and‘y1’attributes converted to user space, respectively
  • perform an absolute lineto operation to absolute location (x2,y2), wherex2andy2are the values of the‘line’element's‘x2’and‘y2’attributes converted to user space, respectively

Because‘line’elements are single lines and thus are geometrically one-dimensional, they have no interior; thus,‘line’elements are never filled (see the‘fill’property).
