<X>: Integer
X coordinate (in pixels) of the point inside the area to color. This position is given in relation to the top left corner of the image control (coordinates set to (0, 0)).
<Y>: Integer
Y coordinate (in pixels) of the point inside the area to color. This position is given in relation to the top left corner of the image control (coordinates set to (0, 0)).
<Fill color>: Integer or constant (optional)
Color used to fill the area. This color can correspond to:
If this parameter is not specified, the fill color:
  • is Transparent if dBackground was not used beforehand,
  • corresponds to the color specified in the last call to dBackground.
<Border color>: Integer or constant (optional)
Area border color. This color can correspond to:
If this parameter is not specified, the area border color adapts to the fill color.
Remarks

Drawing in anti-aliasing mode

When drawing in anti-aliasing mode (drawAntiAliasing constant in the dChangeMode function), the graphics card smoothes the points and colors used at the borders of the shapes.
In this case, <Border color> is not displayed in the drawing and the fill is applied to the entire drawing.

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
    WindowsLinuxJavaUser 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. dStartDrawing becomes useless. This function must be deleted.
