Remarks

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
    WindowsLinux 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.

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.

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 project, on the "Project" pane, in the "Project" group, click "Description".
Special case: Drawing in the browser of an Android phone: The browser drawing functions are only available starting with version 3 of Android.
