dFont([<Image>, ] <Font> [, <Font size> [, <Font attributes> [, <Text inclination>]]])

Versions 24 and later
Reports and QueriesWindowsJavaUser code (UMC) Image to use. This image can correspond to:
  • the name of an Image control.
  • on behalf of an Variable of type Image.

<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.
<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.
iBoldAssigns the bold attribute to the text drawn.
iItalicAssigns the italic attribute to the text drawn.
iNormal
(Default value)
Normalizes the text drawn
iUnderlinedUnderlines the text drawn.
<Text inclination>: Optional integer
Specifies the inclination of the text (in degrees). The default value is 0.

<Font used>: Font

Remarks

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

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

Pattern and 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.
