I was wondering if there's a way to encode an image to a base64 if it was a resource for example if I loaded an image using GD
$image = imagecreatefromjpeg("captcha/$captcha-$num.jpg");
// Add some filters
imagefilter($image, IMG_FILTER_PIXELATE, 1, true);
imagefilter($image, IMG_FILTER_MEAN_REMOVAL);
If this was my code and instead of saving the image and displaying it using
<img src='someimage.jpg'>
I wanted to display it as a data URI without having to save it, like
<img data='src="data:image/jpeg;base64,BASE64_HERE'>
How can I do that?
$image = imagecreatefromjpeg("captcha/$captcha-$num.jpg");
// Add some filters
imagefilter($image, IMG_FILTER_PIXELATE, 1, true);
imagefilter($image, IMG_FILTER_MEAN_REMOVAL);
ob_start(); // Let's start output buffering.
imagejpeg($image); //This will normally output the image, but because of ob_start(), it won't.
$contents = ob_get_contents(); //Instead, output above is saved to $contents
ob_end_clean(); //End the output buffer.
$dataUri = "data:image/jpeg;base64," . base64_encode($contents);
