Description

Methods

Public constructor Create; virtual;

Creates a new instance of TAdTypeSetter. This method should not be called for TAdTypeSetter as it is an abstract class. Use TAdSimpleTypeSetter or other classes derived from TAdTypeSetter instead.

Public function MaxHeight:double;

Returns the maximum width of a char in the font currently loaded into the type setter.

Public function MaxWidth:double;

Returns the maximum width of a char in the font currently loaded into the type setter.

Public procedure GenerateLine(AX,AY:double; AText:string; var ATextSet:TAdTextSet); virtual; abstract;

Generates one line of text.

Parameters
AX
specifies the output X-coordinate of the generated text.
AY
specifies the output Y-coordinate of the generated text.
AText
specifies the text that is actually set.
ATextSet
specifies the output text set that will contain the output data.
Public procedure Generate(ARect:TAdRect; AText:string; var ATextSet:TAdTextSet); virtual; abstract;

Generates the specified text in the given rectangle.

Parameters
ARect
specifies the output rectangle of the text.
AText
specifies the text that is actually set.
ATextSet
specifies the output text set that will contain the output data.
Public procedure Assign(ASource:TAdTypeSetter); virtual; abstract;

Copies the settings from another instance of a type setter class.

Public function CompareTo(ATypeSetter:TAdTypeSetter):boolean; virtual; abstract;

Compares the settings of this instance of the type setter class with another instance and returns whether the settings are equal.

Pointer on the array that contains the sizes of each char.

Public property CharPatterns: TAdCharPatterns read FCharPatterns write FCharPatterns;

Pointer on the array that contains the texture coordinates of each char.

Public property Changed: boolean read FChanged write FChanged;

Returns whether any settings have changed.

Public property TextWidth: integer read FTextWidth;
