Image_Text::set

Image_Text::set() – Set options

Synopsis

require_once 'ImageText.php';

bool Image_Text::set ( mixed $option , mixed $value = null )

Set a single or multiple options. It may happen that you have to reinitialize the Image_Text object after changing options.

Possible options to set
Option	Description
`x`	This sets the top left coordinates (using x/y) or the center point coordinates (using cx/cy) for your text box. The values from cx/cy will overwrite x/y.
`y`
`cx`
`cy`
`canvas`	You can set different values as a canvas: A gd image resource. An array with '`width`' and '`height`'. Nothing (the canvas will be measured after the real text size).
`antialias`	This is usually `true`. Set it to `false` to switch antialiasing off.
`width`	The width and height for your text box.
`height`
`halign`	Alignment of your text inside the textbox. Use alignment constants to define vertical and horizontal alignment.
`valign`
`angle`	The angle to rotate your text box.
`color`	An array of color values. Colors will be rotated in the mode you choose (linewise or paragraphwise). Can be in the following formats: String representing HTML style hex couples (+ unusual alpha couple in the first place, optional). Array of int values using 'r', 'g', 'b' and optionally 'a' as keys.
`color_mode`	The color rotation mode for your color sets. Does only apply if you defined multiple colors. Use 'line' or 'paragraph'.
`background_color`	Defines the background color. Use NULL if you would like to have the background transparent. Default is `#000000`.
`enable_alpha`	If the alpha channel should be enabled. Automatically enabled when background_color is set to NULL. Default is FALSE.
`font_path`	Location of the font to use.
`font_file`
`font_size`	The font size to render text in (will be overwriten if you use automeasurize).
`line_spacing`	Measure for the line spacing to use. Default is `0.5`.
`min_font_size`	Automeasurize settings. Try to keep this area as small as possible to get better performance.
`max_font_size`
`max_lines`	The maximum number of lines to render. Default is `100`.
`image_type`	The type of image (use image type constants). Is default set to `PNG`.
`dest_file`	The destination to (optionally) save your file.
