optional arguments

Every other option will be in the option object.

Valid values are either a number or a valid CSS size value (e.g 200px).
Unless specified units will be measured in characters.
maxHeight"Infinity"String|numSame as maxWidth except that if it is not set the maximum height will be the the same as the height of the original image but in characters instead of pixels.

Textifier comes with some constants so you don't have to memorize this

Functions

There are 3 main functions in Textifier, write, draw and log. There a few other mainly used internally but available anyways since they might come in handy.

write, draw

arguments: (String url, Element element, bool append)

The write and draw functions work exactly the same way. The only difference is that write will print html in a

 tag and the draw will print an actual image on a canvas.

url

type: String

The url of the image to be used.

element

type: Element

The element in which the rendered image will be added to.

append

type: bool

If the rendered image should be appended or replace the contents of the target element.

Example
  new Textifier(maxWidth: 100, characters: 'oink', ordered: true).draw('images/piggies.png', target);
Output

Rendered image

log

arguments: (String url)

The log function will print the image in the dev console of your browser.

url

type: String

The url of the image to be used.

Example
  new Textifier(maxWidth: 100, characters: 'oink', ordered: true).log('images/piggies.png');
Output

Rendered image

Constants

Textifier comes with some "constants" so you don't have to remember arguments that are numbers and to make your code more readable.

  Textifier.COLORED = 0;
  Textifier.GRAYSCALE = 1;
  Textifier.MONOCHROME = 2;

  Textifier.HTML = 0;
  Textifier.CANVAS = 1;
  Textifier.CONSOLE = 2;
