i'm creating a web application to generate images according to user's input, more precisely a barcode generator. i'm using javascript to process the data input by user. In the end, i want to have my output barcode as an jpg or png. What other tools do i need? I know that javascript cannot create the .jpg or .png file for me. What other tools can help me generate an image file?

• Pretty much any server side language. Are you using php, or something else? – Adam Hopkinson Commented Jan 6, 2012 at 9:04

I have created previews of user driveways after pavement using PHP GD with a picture submitted by the user.

It's done with PHP so you would POST the data to a PHP script on the server side and create the image from there.

I went as far as having the user click and make a path of the section to remove (the old driveway) and use that to cut out the driveway and replace it with a background layer.

You can set up PHP locally with Apache or IIS. PHP is pretty much standard on all hosting services.

You could build an image editor with it.
