[Plugin: POST2PDF Converter] TCPDF Error with images

Hi, lucile san

getimagesize() [function.getimagesize]: php_network_getaddresses: getaddrinfo failed: Name or service not known in

Maybe, your server can’t resolve the own domain name to IP address and fail to open image files.

You may need to modify hosts on the serevr to resolve this issue.

You had better consult with the server administrator.

Hi redcocker,

Thanks a lot, we modified /etc/hosts on our server by adding the IP and the name of the site, and it works perfectly!

Thanks again!

One more question… Do you confirm that the pdfs are generated locally and that no data are sent outside?
Thanks!

Hi, lucile san

Do you confirm that the pdfs are generated locally and that no data are sent outside?

Only when “Cache” option is enable or using “4.PDF Converter” in the setting panel, PDF is generated in the server disk.

This plugin doesn’t sent any data outside.
But I don’t know whether TCPDF sents data outside or not
I believe that TCPDF is not such a PHP class.
Because TCPDF is widely used.

Thanks for these info.

Actually we have an other problem, with png and bmp images.

The error message when a post contains png file is:

Fatal error: Uncaught exception ‘ImagickException’ with message ‘unable to open file my_wp_path_on_my_server/wp-content/plugins/post2pdf-converter/https://xxxxx.xxx.xx/wp-content/uploads/2012/02/bullet.png” in my_wp_path_on_my_server/wp-content/plugins/post2pdf-converter/tcpdf/tcpdf.php:8255 Stack trace: #0 my_wp_path_on_my_server/wp-content/plugins/post2pdf-converter/tcpdf/tcpdf.php(8255): Imagick->readimage(‘https://xxxxx….’) #1 my_wp_path_on_my_server/wp-content/plugins/post2pdf-converter/tcpdf/tcpdf.php(7724): TCPDF->ImagePngAlpha(‘https://xxxxx….’, 16.000125, 100.751722222, 45.3543307087, 45.3543307087, 4.51555555556, 4.51555555556, ‘PNG’, ‘https://xxxxx….’, ‘B’, false, 300, ”, ‘b7b6cd0ce801d07…’) #2 my_wp_path_on_my_server/wp-content/plugins/post2pdf-converter/tcpdf/tcpdf.php(23225): TCPDF->Image(‘https://xxxxx….’, 16.000125, 100.751722222, 4.51555555556, 4.51555555556, ”, ‘https://xxxxx….’, ‘B’, false, 300, ”, false, false, 0, false, false, true) #3 my_wp_path_on_my_server/wp-content/plugins/post2pdf-convert in my_wp_path_on_my_server/wp-content/plugins/post2pdf-converter/tcpdf/tcpdf.php on line 8255

For the bmp files, it’s simply:

TCPDF ERROR: [Image] Unable to get image: https://xxxxx.xxxx.xx/wp-content/uploads/2012/02/test.bmp

Our Linux distribution is Ubuntu 8.04 LTS with the last version of ImageMagick for this version (dpkg -s ImageMagick => Version: 7:6.3.7.9.dfsg1-2ubuntu1.2)

If you have any idea…

Hi, lucile san

Sorry I have no definitive answer.

we modified /etc/hosts on our server by adding the IP and the name of the site, and it works perfectly!

I think you can try to add your domain name to following line in hosts.

127.0.0.1 localhost xxxxx.xxxx.xx
* xxxxx.xxxx.xx = YOUR_DOMAIN

If you have added server’s global IP and your domain name, try to delete them.
