ParseFontSize(String,Single,Single,Boolean,TSVGUnitFactors) Method

Contents

Parses the input string for a font size value, which refers to the size of the font from baseline to baseline when multiple lines of text are set solid in a multiline layout environment.

The allowable inputs are absolute-size | relative-size | length | percentage | inherit

Namespace: RSSVGUtils

Delphi

function ParseFontSize( S: String; DefValue, ParentSize: Single;
var Inherits: Boolean; UnitFactors: TSVGUnitFactors ): Single;

Parameters

Type: String

DefValue

Type: Single

ParentSize

Type: Single

Inherits

Type: Boolean

UnitFactors

Type: TSVGUnitFactors

Return Value

Type: Single

If the string is blank, the function returns the default value ( DefValue). If the string contains 'inherits', the function returns the default value and sets the Inherits parameter to true.

Note
The UnitFactors parameter specifies the unit factors for conversion of string lengths into actual values. For example, if the input string contains '1cm', the function uses the UnitFactors to know how large a centimer is. It is usually set when the DPI property of the TSVGDocument element is set.
