TCPDF error :Unable to get the size of the image
I am using TCPDF to create dynamically generated pdf file . In my pdf file a image is generated based on user input and I want to add that image on my pdf file . Here is my code
$map_image = "example.com/wp-content/themes/example/map_image_leasing.php/?city=Calgary&suit_type=&min_area=&max_area=";
$pdf->Image ($map_image, 55, 19, '', '', 'JPG', '', 'T', false, 300, '', false, false, 0, false, false, false);
If i paste "example.com/wp-content/themes/example/map_image_leasing.php/?city=Calgary&suit_type=&min_area=&max_area=" this on my url this create image as I wanted , but If put this url , it doesn't work . It says Unable to get the size of the image
But if I put something like this
$map_image = '/wp-content/themes/v3/resources/images/public/logo_side.jpg';
It can generate pdf with that image successfully .
How can I solve it ?
I have visited the following stackoverflow link , but none of this came to any help
Answer
This might be due to filesize() failing to stat() the remote image file via the HTTP wrapper (since the wrapper doesn't support it).
According to the TCPDF image() method documentation you can pass the image data in directly by prepending it with an @ symbol. So you could get the raw image data and then pass it to TCPDF like so:
$img = file_get_contents('http://example.com/wp-content/themes/example/map_image_leasing.php/?city=Calgary&suit_type=&min_area=&max_area=');
$pdf->Image('@' . $img, 55, 19, '', '', 'JPG', '', 'T', false, 300, '', false, false, 0, false, false, false);
Note that I haven't tested this (and the TCPDF documentation is sparse) so you might need to experiment a little to get it to work correctly.
Edit:
This is a fully working example (on my PC). Use this to test if you can successfully retrieve the image and output the PDF to your browser. Of course you'll need to set a known valid path for the image!
<?php
require './tcpdf/tcpdf.php';
$pdf = new TCPDF();
$pdf->AddPage();
$img = file_get_contents('http://path/to/your.jpg');
$pdf->Image('@' . $img);
$pdf->Output();
?>
