SVG preserveAspectRatio interface

SVGPreserveAspectRatio interface corresponds to the preserveAspectRatio attribute, which is available for some of SVG's elements.

An SVGPreserveAspectRatio object can be designated as read only, which means that attempts to modify the object will result in an exception being thrown.

常量

名称	值	描述
`SVG_` `PRESERVEASPECTRATIO` `_UNKNOWN`	0	The enumeration was set to a value that is not one of predefined types. It is invalid to attempt to define a new value of this type or to attempt to switch an existing value to this type.
`SVG_` `PRESERVEASPECTRATIO` `_NONE`	1	Corresponds to value `none` for attribute `preserveAspectRatio` .
`SVG_` `PRESERVEASPECTRATIO` `_XMINYMIN`	2	Corresponds to value `xMinYMin` for attribute `preserveAspectRatio` .
`SVG_` `PRESERVEASPECTRATIO` `_XMIDYMIN`	3	Corresponds to value `xMidYMin` for attribute `preserveAspectRatio` .
`SVG_` `PRESERVEASPECTRATIO` `_XMAXYMIN`	4	Corresponds to value `xMaxYMin` for attribute `preserveAspectRatio` .
`SVG_` `PRESERVEASPECTRATIO` `_XMINYMID`	5	Corresponds to value `xMinYMid` for attribute `preserveAspectRatio` .
`SVG_` `PRESERVEASPECTRATIO` `_XMIDYMID`	6	Corresponds to value `xMidYMid` for attribute `preserveAspectRatio` .
`SVG_` `PRESERVEASPECTRATIO` `_XMAXYMID`	7	Corresponds to value `xMaxYMid` for attribute `preserveAspectRatio` .
`SVG_` `PRESERVEASPECTRATIO` `_XMINYMAX`	8	Corresponds to value `xMinYMax` for attribute `preserveAspectRatio` .
`SVG_` `PRESERVEASPECTRATIO` `_XMIDYMAX`	9	Corresponds to value `xMidYMax` for attribute `preserveAspectRatio` .
`SVG_` `PRESERVEASPECTRATIO` `_XMAXYMAX`	10	Corresponds to value `xMaxYMax` for attribute `preserveAspectRatio` .
`SVG_MEETORSLICE_UNKNOWN`	0	The enumeration was set to a value that is not one of predefined types. It is invalid to attempt to define a new value of this type or to attempt to switch an existing value to this type.
`SVG_MEETORSLICE_MEET`	1	Corresponds to value `meet` for attribute `preserveAspectRatio` .
`SVG_MEETORSLICE_SLICE`	2	Corresponds to value `slice` for attribute `preserveAspectRatio` .

特性

名称	类型	描述
`align`	unsigned short	The type of the alignment value as specified by one of the SVG_PRESERVEASPECTRATIO_* constants defined on this interface.
`meetOrSlice`	unsigned short	The type of the meet-or-slice value as specified by one of the SVG_MEETORSLICE_* constants defined on this interface.
