Syntax

Using a specific font for the drawings Hide the details

dFont(<Font> [, <Font Size> [, <Font Attributes> [, <Text Inclination>]]])
<Font>: Character string
Name of the font used when the text is drawn by dText. This parameter must not correspond to a font family. The list of fonts installed on the current computer is returned by FontList.
Java If the name of the font is not found, Windows searches for a font whose name is close to the requested one. To do so, dStartDrawing must have been used.
Android The name of the font will be ignored: the default system font is used.
<Font Size>: Optional integer
Size of the font (in pixels). The default value is 12.
<Font Attributes>: Optional constant (or combination of constants)
Font attributes to use:
iStrikeOutStrikes the text drawn.
Versions 16 and later
WEBDEV - Browser code This constant is not supported.

Using a font created by programming Hide the details

dFont(<Font Used>)
<Font Used>: Font
Font that will be used for the drawings. This parameter corresponds to a Font variable. The font characteristics have been defined by FontCreate or via the properties for font management.
Remarks

Using the drawing functions

  • 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.

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.
PHP

Fonts in PHP

To use the formatting attributes (bold, italic, ...), the files of corresponding fonts must be accessible (ttf files). These files must be found in the site directory ( _WEB directory returned by fWebDir) and they must be named as follows:
  • <Name of standard font>
  • <Name of standard font>_Bold
  • <Name of standard font>_Italic
  • <Name of standard font>_Italic_Bold
The management of the underlined is automatic like the management of &.
If no font is found, the text will be normal, without management of &.
PHP

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.

WEBDEV - Browser code

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". This option is available in the "Advanced" tab of the description window of the project ("Project .. Project description").
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 the project, on the "Project" pane, in the "Project" group, click "Description".
