// Symmetry of IMG_IMAGE1 with respect to a horizontal axis
MyResult is boolean
MyResult = dHorizontalSymmetry(IMG_IMAGE1)
IF MyResult = False THEN Error("The operation failed")
<Result> = dHorizontalSymmetry(<Image>)
<Result>: Boolean
  • True if the symmetry was performed,
  • False otherwise.
<Image>: Name of Image control, Image, WDPic or picLayer variable
Image to use. This image can correspond to:

The transformation of the image will not be displayed if dEndDrawing and dHorizontalSymmetry are called in the same process.

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.
Component: wd260pnt.dll
Minimum version required
  • Version 9
