If this parameter is not specified, it is necessary to define the drawing destination with dStartDrawing.
<X-coordinate>: Integer
X coordinate of the RTF text to draw (in pixels).
<Y-coordinate>: Integer
Y coordinate of the RTF text to draw (in pixels).
<RTF text>: Character string
RTF text to draw.
<Width>: Optional integer
Maximum width of the text. No maximum width is defined by default.
<Height>: Optional integer
Maximum height of the text. No maximum height is defined by default.
Remarks

Coordinates

The coordinates are given in relation to the top left corner of the image or Image control ((0, 0) coordinates).
The coordinates correspond to the top left corner of the rectangle into which the text will be drawn.

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
    Reports and QueriesWindowsUser code (UMC) 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.
