dFill (Function) In french: dRemplissage // Initialize the drawing in an Image control dStartDrawing(IMG_Drawing) // Color an area in light blue dFill(10, 50, LightBlue)
Syntax
dFill([<Image>, ] <X> , <Y> [, <Fill color> [, <Border color>]])
<Image>: Optional control name or optional Image, WDPic or picLayer variable
<X>: Integer X-coordinate (in pixels) of the point inside the area to color. This position is given in relation to the upper-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 upper-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 has not been 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 dChangeMode), the graphics card smooths out the points and colors used in the border of 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 the dDrawingStartfunction
- 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.
If function dEndDrawing is called in the same process as function dStartDrawing, the drawing will not appear: it will be automatically deleted.
 Method 2: Indicate the design destination 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.
