  • Article

For additional notes that apply to this portion of the standard, please see the notes for pict, §14.2.2.2(a); pict, §14.5.1(a); hdrShapeDefaults, §14.7.2.1(a); shapeDefaults, §14.7.2.2(a); background, §17.2.1(a); column, §19.2.2.6(a).

a.   The standard indicates the conditions under which the bottom element is displayed.

In Office, the bottom element will only be displayed if all of the following conditions are met:

  • The on attribute is true.

  • The shape’s path is closed with the x command.  [Note: This implies that arrow heads should be defined on the stroke attribute. end note]

  • The shape’s path defines a rectangle with corner coordinates exactly equal to 0,0; 21600,0; 21600,21600; 0,21600.  [Example: For example, the following value on the path attribute of the shape element ("[ISO/IEC-29500-4] §19.1.2.19; shape (Shape Definition)") satisfies this condition: path="m,l,21600r21600,l21600,xe" end example]

  • The value of the shape’s spt attribute is 202.

  • The shape is not stroked.

[Note: The shape is not stroked if one of the following conditions is true:

  • The value of the on attribute of the stroke element ("[ISO/IEC-29500-4] §19.1.2.21; stroke (Line Stroke Settings)") is false.

  • The on attribute of the stroke element is absent and the value of the shape’s stroked attribute is false.

  • The on attribute of the stroke element is absent, the shape’s stroked attribute is absent and the value of the stroked attribute of the shapetype element ("[ISO/IEC-29500-4] §19.1.2.20; shapetype (Shape Template)") is false.

end note]

b.   The standard indicates how the src attribute is used.

Office replaces the value of the src attribute with the value of the href attribute, if defined, or the althref attribute if href is not defined.

c.   The standard indicates in the on attribute the conditions under which the bottom element is displayed.

In Office the bottom element is only displayed if the on attribute is true, if the shape's path is closed with the x command, and the shape is not stroked.

d.   The standard indicates how the href attribute is used.

Office does not persist this value on file save.  The href attribute value replaces the value of the src attribute on file save.

e.   The standard indicates how the althref attribute is used.

Office does not persist the althref value on file save.  The althref attribute value replaces the value of the src attribute on file save if the href attribute is not defined.

f.   The standard states that imageaspect is a valid attribute on this element.

Office does not support this attribute on this element; if a value other than ignore is specified, a value of 0,0 will be applied to the imagesize attribute.

g.   The standard indicates how the imagesize attribute is used.

This attribute is specified as a string of two numbers separated by a space, colon, semicolon or comma.  The valid unit ranges for the numbers are defined in section 6.1.  If these limits are not respected, Office writes a value of “0,0” on file save.

If more than two values are defined, only the two first values are used and saved.

h.   The standard does not specify bounds for the weight attribute.

In Office, the minimum value for the weight attribute is zero and the maximum value is 20116800 EMU.

i.   The standard does not specify bounds for the miterlimit attribute.

Office uses a maximum value of 32767 for the miterlimit attribute.

j.   The standard indicates that the default value for the weight attribute is 1 pt.

Office uses a default of 0.75 pt for the weight attribute.

k.   The standard states that values of the opacity attribute are defined by the XML Schema string datatype.

Office defines the values of the opacity attribute with the ST_Fraction §3.9.1, ST_Fraction) simple type.
