In my case want to prevent dataUrl/base64 since I need a Array buffer or view. Instead of toDataURL (as all questions here propose). This is the other way, without strings although I don't really know if it's faster or not. or as transparent PNG imagesavealpha($img, true) Imagecopy($output, $img, 0, 0, 0, 0, $width, $height) Imagefilledrectangle($output, 0, 0, $width, $height, $white) $output = imagecreatetruecolor($width, $height) export image as JPEG $width = imagesx($img) $img = imagecreatefromstring(base64_decode(substr($data,strpos($data,',') 1))) Header("Expires: 0") header("Cache-Control: must-revalidate") Header("Content-Transfer-Encoding: binary") Header("Content-Disposition: attachment filename=\"$filename\"") Header("Content-type: application/octet-stream") Header("Content-type: application/force-download") else If($msie = !strstr($_SERVER,"MSIE")=false) ![]() Header('Content-Description: File Transfer') Set the headers $filename = "test.jpg" //or png Here is some help if you do the download through a server (this way you can name/convert/post-process/etc your file): It is also worth mentioning that if you use any cross-domain resources in rendering your canvas, you will encounter a security error when you try to use the toDataUrl method. ![]() ![]() If you're using that with different mime types, be sure to change both instances of image/png, but not the image/octet-stream. Var image = canvas.toDataURL("image/png").replace("image/png", "image/octet-stream") //Convert image to 'octet-stream' (Just a download, really) If you wish to make the user download the file as it is saved you can do the following: var canvas = document.getElementById("mycanvas") You only need to run this once per page - it should never change through a page's lifecycle. If you would like an array of the supported types you can do something along the lines of this: var imageMimes = //Extend as necessaryĪcceptedMimes = imageMimes Where "image/png" is a mime type (png is the only one that must be supported). You can use this to write the image to the page: document.write('') Var image = canvas.toDataURL("image/png") ![]() In order to get the canvas as an image, you should do the following: var canvas = document.getElementById("mycanvas") I thought I'd extend the scope of this question a bit, with some useful tidbits on the matter. ![]()
