Bounds Property

Summary

Gets the physical (pixel) bounds and resolution of this SvgDocument.

Syntax

Objective-C

C++/CLI

Java

Python

public SvgBounds Bounds { get; }

- (nullable LTSvgBounds *)bounds:(NSError **)error;

public SvgBounds getBounds()

public: 
property SvgBounds Bounds { 
   SvgBounds get(); 
}

Bounds # get  (SvgDocument)

Property Value

The physical (pixel) bounds and resolution of this SvgDocument.

Remarks

For more information about flat SVG documents and bounds and resolution, refer to SVG Size, Bounds and Flat.

Before calling CalculateBounds, the value of Bounds.IsValid will be false and the document does not have its physical (pixel) bounds calculated. The rest of SvgBounds members should not be used.

The CalculateBounds method will calculate the physical (pixel) bounds of the document by internally enumerating all the elements and resolving the transformation. When this method returns, the members of Bounds will be set as follows:

Member	Description
SvgBounds.IsValid	true
SvgBounds.IsTrimmed	The value of 'trimmed' passed to CalculateBounds
SvgBounds.Resolution	A value such as 96 or 300 DPI calculated automatically from the SVG elements. If this value cannot be calculated, it will be set to the default value of 0.
SvgBounds.Bounds	The document physical boundaries in pixels.

Use SetBounds to set the physical (pixel) bounds of the document manually.

Use Flat and ToFlat to flatten a document in-place or return a flat copy of an SvgDocument.

Use IsFlat to determine whether this SvgDocument is flat. Use SetFlat to set or clear the internal flattening flag without re-calculating the document's bounds.
