IF Result1 = False THEN Error("The operation failed")
Syntax
<Result> = <Image control>.Resize(<New width> , <New height> [, <Option>])
<Result>: Boolean
  • True if the resize operation was performed,
  • False otherwise.
<Image control>: Control name

Remarks

End of drawing

The transformation of the image will not be displayed if <Image>.EndDrawing and <Image>.Resize are called in the same process.
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.
Versions 16 and later
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 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.
