Detailed Description

SVG preserveAspectRatio attribute.

Controls how an SVG element with a viewBox is scaled and aligned within its viewport. See the SVG specification for details.

Member Enumeration Documentation

◆ Align

enum AeonGUI::PreserveAspectRatio::Align : uint8_t

Combined X and Y alignment values for preserveAspectRatio.

Enumerator
none	Do not force uniform scaling.
XMinYMin	Align X-min, Y-min.
XMinYMid	Align X-min, Y-mid.
XMinYMax	Align X-min, Y-max.
XMidYMin	Align X-mid, Y-min.
XMidYMid	Align X-mid, Y-mid (default).
XMidYMax	Align X-mid, Y-max.
XMaxYMin	Align X-max, Y-min.
XMaxYMid	Align X-max, Y-mid.
XMaxYMax	Align X-max, Y-max.

◆ MeetOrSlice

enum class AeonGUI::PreserveAspectRatio::MeetOrSlice

strong

Meet-or-slice scaling strategy.

Enumerator
Meet	Scale to fit entirely within the viewport.
Slice	Scale to cover the viewport, clipping overflow.

◆ MinMidMax

enum AeonGUI::PreserveAspectRatio::MinMidMax : uint8_t

Axis alignment selector values.

Enumerator
Min	Align to the minimum (start) edge.
Mid	Align to the midpoint.
Max	Align to the maximum (end) edge.

Constructor & Destructor Documentation

◆ PreserveAspectRatio()

AeonGUI::PreserveAspectRatio::PreserveAspectRatio ( std::string_view aString )

Construct from a string representation.

Parameters

aString A string such as "xMidYMid meet".

Member Function Documentation

Returns: Min, Mid, or Max for the X axis.

◆ GetAlignY()

PreserveAspectRatio::MinMidMax AeonGUI::PreserveAspectRatio::GetAlignY ( ) const

Get the Y-axis alignment component.

Returns: Min, Mid, or Max for the Y axis.

◆ GetMeetOrSlice()

PreserveAspectRatio::MeetOrSlice AeonGUI::PreserveAspectRatio::GetMeetOrSlice ( ) const
