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 are:
'x' | This sets the top left coordinates (using x/y) or the center point
'y' | coordinates (using cx/cy) for your text box. The values from
'cx' | cx/cy will overwrite x/y.
'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.
'halign' | Alignment of your text inside the textbox. Use alignmnet constants to define
'valign' | vertical and horizontal alignment.
'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'.
'font_path' | Location of the font to use.
'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
'max_font_size' | performance.
'image_type' | The type of image (use image type constants). Is default set to PNG.
'dest_file' | The destination to (optionally) save your file.
