: Character string

Name of the font used when the text is drawn by dText. This parameter must not correspond to a font family. The list of fonts installed on the current computer is returned by FontList.
If the name of the font is not found, Windows searches for a font whose name is close to the requested one. To do so, dStartDrawing must have been used.

: Optional integer

Size of the font (in pixels). The default value is 12.

: Optional constant (or combination of constants)

Font attributes to use:
iStrikeOut Strikes the text drawn.
iBold Assigns the bold attribute to the text drawn.
iItalic Assigns the italic attribute to the text drawn.
iNormal
(Default value) Normalizes the text drawn
iUnderlined Underlines the text drawn.

<Text inclination>: Optional integer

Specifies the inclination of the text (in degrees). The default value is 0.

Remarks

Using the drawing functions

The drawing functions can be used according to 2 methods:

Method 1: Using dStartDrawing
- dStartDrawing must be called before any other drawing function. dStartDrawing is used to define the element (Image control or variable) to which the drawing functions will be applied.
- When drawing on an Image control:
  - The drawing functions operate on a copy ("bitmap") of the image. You can use the drawing functions of Windows (via API or CallDLL32) but these functions must use the DC (Device Context) returned by dStartDrawing.
  - dEndDrawing and dStartDrawing must not be called in the same process.
    The drawing will not be displayed if dEndDrawing and dStartDrawing are called in the same process: it will be automatically erased.
Versions 24 and later
Method 2: indicating the drawing target directly in the syntax (via a parameter)
The <Image> parameter is used to specify directly the target of the drawing. The dStartDrawing function becomes unnecessary. This function must be deleted.
Versions 25 and later
This syntax is now available.

Fonts

FontList is used to retrieve the list of valid fonts (TrueType, PostScript) installed on the current computer.

To get good results when angling the text drawn, the used must be a "True Type" font.
