TCPDF Add Image Rendered By Php

i am having issues to add image on pdf file using tcpdf. my image is rendered by php script.

below is the script call mode: (worked well when directly check on browser):

./Image.php?t=1049&e=100003&i=25040907060040

but when i try to add using tcpdf using below code:

$pdf->Image('./Image.php?t=1049&e=100003&i=25040907060040', '', '',  20, 20, 'jpg', '', 'T', false, 300, '', false, false, 0, false, false, false);

it fails with following errors:

Error 1:

Warning: getimagesize(./Image.php?t=1049&e=100003&i=25040907060040): failed to open stream: No error in .\Classes\tcpdf\include\tcpdf_images.php on line 171

Error 2:

Warning: imagecreatefromjpeg(./Image.php?t=1049&e=100003&i=25040907060040): failed to open stream: No error in .\Classes\tcpdf\tcpdf.php on line 7033

so, how can i add image using above php script (Image.php)?

thanks in advance

It fails because your code looks for a data stream for image data.

The best solution is to include Image.php which will have a function to output image data.

Suppose the Image.php have class ImageRenderer with a public function called render_image();

The you can have the image rendered to the PDF like this..

require_once('Image.php');

$dynimage = ImageRenderer::render_image(1049,100003,25040907060040); // Parameters t=1049&e=100003&i=25040907060040
// $dynimage will have some data like 'iVBORw0KGgoAAAANSUhEUgAAABwAAAASCAMAAAB/2U7WAAAABlBMVEUAAAD///+l2Z/dAAAASUlEQVR4XqWQUQoAIAxC2/0vXZDrEX4IJTRkb7lobNUStXsB0jIXIAMSsQnWlsV+wULF4Avk9fLq2r8a5HSE35Q3eO2XP1A1wQkZSgETvDtKdQAAAABJRU5ErkJggg=='
$imgdata = base64_decode($dynimage); // decode stream
// The '@' character is used to indicate that follows an image data stream and not an image file name
$pdf->Image('@'.$imgdata);

Hope this helps!
