HTML2pdf converts html into html and the image is lost.

HTML2pdf: convert html into html.

The converted pdf file does not exist.

I use regular expressions to replace the image and insert it into the image.
$ Pattern = "// I ";
Preg_match_all ($ pattern, $ file, $ match );
Var_dump ($ match );
For ($ I = 0; $ I $ Img_url = preg_match ("/^ http: \\//", $ match [1] [$ I])? $ Match [1] [$ I]: "http://file.aconf.org". $ match [1] [$ I];
Preg_replace ($ match [0] [$ I], $ pdf-> Image ($ img_url, 5, 5,200,150, $ type = '', $ link = "", $ paint = true), $ file );
}
$ Pdf-> Image ($ img_url, 5, 5,200,150, $ type = '', $ link =" ", $ paint = true );
Error

Please give me some advice.

Make sure your image format is accepted (JPEG, PNG)
Make sure that the remote image can be read using the file function (if the recipient has anti-Leech protection, the image cannot be read)

The image is jpg and can be read for sure.

Vendor('html2fpdf.html 2fpdf ');
$ Pdf = new FPDF ();
$ Pdf-> AddPage ();
$ Pdf-> SetFont ('arial', 'B', 16 );
$ Pdf-> Cell (, 'Hello World! ');
$ Pdf-> Image ('http: // file.aconf.org/public/images/logo.png', 'png ');
$ Pdf-> Output ();
