Summary

Represents the calculated bounds of an SVG document.

Syntax

Objective-C

C++/CLI

Java

Python

[SerializableAttribute()] 
public struct SvgBounds

@interface LTSvgBounds : NSObject <NSCopying, NSCoding>

public class SvgBounds

[SerializableAttribute()] 
public value class SvgBounds : public System.ValueType

class SvgBounds:

Remarks

Value of SvgDocument.Bounds.

The SvgBounds is usually calculated and set by the SvgDocument.CalculateBounds method as follows:

Member	Value
IsValid	true to indicate the rest of the members of this structure are valid
IsTrimmed	The same value as the "trimmed" parameter passed to SvgDocument.CalculateBounds
Bounds	The calculated bounds in physical units (pixels)
Resolution	The resolution of the document calculated in dots per inch (DPI)
