Example

dFill(10, 50, LightBlue)

Versions 24 and later

// Color an area in light blue
dFill(IMG_Drawing, 10, 50, LightBlue)

New in version 24

// Color an area in light blue
dFill(IMG_Drawing, 10, 50, LightBlue)

Syntax

dFill([<Image>,] <X> , <Y> [, <Fill color> [, <Color of limits>]])

<Image>: Optional control name or optional Image variable

Versions 24 and later
Image to use. This image can correspond to:
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.
New in version 24
Image to use. This image can correspond to:

Image to use. This image can correspond to:
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.

<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 corresponds to:
an RGB color (returned by RGB),
an HSL color (returned by HSL),
a preset color of WLanguage.
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.

<Color of limits>: Integer or constant (optional)

Color for the limits of the area. This color corresponds to:
an RGB color (returned by RGB),
an HSL color (returned by HSL),
a preset color of WLanguage.
If this parameter is not specified, the color for the limits of the area 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, <Color of limits> is not displayed in the drawing and the fill operation is performed on the entire drawing.

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
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.

Drawing in PHP

In PHP, the drawing functions are based on the graphic library GD. This library is commonly used by the PHP hosting companies and therefore it is always enabled. The version of the GD library must be version 2.0.28 (or later). This library can be downloaded from the PHP site.

To enable (if necessary) this library locally, the following elements are required:

PHP installed.
the PHP.INI file found in the Windows directory must contain the following line: "extension=php_gd2.dll" (instead of ";extension=php_gd2.dll").
the php_gd2.dll file must exist in the directory of PHP extensions. This directory is defined in the PHP.INI file by the "extension_dir" variable.

Limitation for dFill: The opacity defined by dBackground is ignored.

Versions 16 and later

Drawing in Browser code

Some drawing functions are available in Browser code. The drawing functions in Browser code are based on the HTML 5 standard. More specifically, these functions are based on the "canvas" tag of HTML 5.

The drawing features in browser code are available for the recent browsers only (supporting the HTML 5 standard). To find out whether the drawing features are proposed by your browser, use DrawingAvailable.

Caution: To use the drawing functions with Internet Explorer 9, the project must "include the reference to the DTD file". This option is available in the "Advanced" tab of description window of project ("Project .. Project description"), "Advanced" button, "W3C standard" option.

Caution: To use the drawing functions with Internet Explorer 9, the project must include the reference to the DTD file. To do so, the HTML mode must be "HTML 4.01 Transitional + DTD". This option is available in the "Advanced" tab of the description window of project.
Reminder: To display the description window of project, on the "Project" pane, in the "Project" group, click "Description".
