Using a specific font for the drawings Hide the details

dFont([<Image>, ] <Font> [, <Font size> [, <Font attributes> [, <Text inclination>]]])
<Image>: Optional control name or optional Image variable
Versions 24 and later

  • the name of an Image control.
  • the name of an Image variable.
If this parameter is not specified, it is necessary to define the drawing destination with dStartDrawing.

<Font>: Character string

<Font attributes>: Optional constant (or combination of constants)
Font attributes to use:
iStrikeOutStrikes the text drawn.

Remarks

Using the drawing functions

The drawing functions can be used according to 2 methods:
  • Method 1: Using dDrawing
    • dStartDrawing must be called before any other drawing function. dStartDrawing is used to define the element (Image control or Image variable) onto 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
    Reports and QueriesWindows 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. dStartDrawing becomes useless.

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 <Font> used must be a "True Type" font.
