Use the form below to generate your own excoffized pictures. Works in any SVG enabled browser (Firefox, Opera, Safari, IE with SVG plugin).

Link to image:
jpeg, png, or gif file, less than 128KB in size.

theta (0 to 3.14) main angle of the lines that form the picture
wiggle (0 to 30): The greater the value, the more the lines wiggle
line height (1 to 100): The greater the value, the further apart the lines

The values below are for fine tuning of the picture
Sx: Sy: scale factor for the lines
Tx: Ty: Position of the lines relative to the picture

Warning: image generation time is limited to 10 seconds. Depending on the size of the original image certain combination of the parameters, computing a picture can be rather slow. In order not to overload my server, any computation that lasts longer than that will be aborted and will produce an error. If you want more time, you're welcome to can download the source and run it locally.

What is it?

Excoffizer takes a picture and produces a vector rendition of the picture, made of parallel lines of varying thickness. It is inspired by Roger Excoffon's pictograms for the 1968 Grenoble Winter Olympics.

The parameters specified in the form control the lines: wiggliness, width, direction, etc. The set of lines computed by those parameters is superimposed on the original image, which determines the varying width of each line. If you want to know more, drop me a line or download the (somewhat obscure) source: index.phps, excoffize.phps, excoffizer-params.phps, utils.phps.

The development of this hack has produced a few interesting yet unintended images, due to the author's uniquely crude programming style. See the "Work in Progress" series for a few.
