image "save" to webpage???
Jan 18th, 2009, 7:04pm  
Hi All:
I was wondering if there is a way (via javascript?) to  copy an image from a Processing applet out to an HTML image to the wrapping page?

I don't think so. At least not in a simple (and portable) way...

I can think of some convoluted ways...

I shown somewhere else in this forum (save to web --- image export) how to save an image on a Web server. You can then call JavaScript to tell it to update the page dynamically to show this image.

Another possibility, purely working on client side, but excluding some browsers (the Internet Explorer family!), could be to encode in Base-64 the image (in Jpeg/PNG format), then to transmit it to JavaScript and use the "data:image/png;base64," method in the src to display it.

If you use Processing.js (http://ejohn.org/blog/processingjs/), you're able to right click and save the applet as an image.. at least in Firefox.

-edit-
apparently not working anymore

BUT you could use http://ajaxian.com/archives/canvas2image-save-out-your-canvas-data-to-images with Processing.js, and some links outside the applets that save the content of the canvas using Javascript
