Overload Details

Overload 1

procedure RenderText(X, Y: TFloat; const Text: string); overload;

Renders text at position (X, Y) using default text layout settings.

Parameter	Type	Description
X, Y	TFloat	Text baseline origin coordinates.
Text	string	Text string to render.

Overload 2

procedure RenderText(X, Y: TFloat; const Text: string; Flags: Cardinal); overload;

Renders text at position (X, Y) using text alignment flags.

Parameter	Type	Description
X, Y	TFloat	Text baseline origin coordinates.
Text	string	Text string to render.
Flags	Cardinal	Win32 DrawText-compatible formatting flags (e.g., DT_CENTER, DT_VCENTER).

Overload 3

procedure RenderText(X, Y: TFloat; const Text: string; const Layout: TTextLayout); overload;

Renders text at position (X, Y) using a TTextLayout structure.

Parameter	Type	Description
X, Y	TFloat	Text baseline origin coordinates.
Text	string	Text string to render.
Layout	TTextLayout	Text layout configuration.

Overload 4

procedure RenderText(const DstRect: TFloatRect; const Text: string; Flags: Cardinal); overload;

Renders text formatted within destination rectangle DstRect using text formatting flags.

Parameter	Type	Description
DstRect	TFloatRect	Destination rectangle for text layout and alignment.
Text	string	Text string to render.
Flags	Cardinal	Formatting flags controlling text alignment and line wrapping.

Overload 5

procedure RenderText(const DstRect: TFloatRect; const Text: string; const Layout: TTextLayout); overload;

Renders text formatted within destination rectangle DstRect using a TTextLayout structure.

Parameter	Type	Description
DstRect	TFloatRect	Destination rectangle for text layout and alignment.
Text	string	Text string to render.
Layout	TTextLayout	Text layout configuration.

Description

RenderText converts character font outlines into vector path contours and appends them to the active canvas path.

Font outlines are converted using backend text-to-path interfaces (ITextToPathSupport or ITextToPathSupport2) supported by the target Bitmap backend.

The converted glyph contours are drawn using the current canvas brushes and polygon renderer.

Example

var
  Canvas: TCanvas32;
  SolidBrush: TSolidBrush;
begin
  Canvas := TCanvas32.Create(MyBitmap);
  try
    SolidBrush := TSolidBrush(Canvas.Brushes.Add(TSolidBrush));
    SolidBrush.FillColor := clBlack32;

    // Render text string at coordinate (20, 40)
    Canvas.RenderText(20.0, 40.0, 'Hello Graphics32!');
  finally
    Canvas.Free;
  end;
end;
