wp-includes/class-wp-image-editor-gd.php and media.phpWarnings

Thanks for the bug report AwagnerA. A few questions:

– Which theme are you running?
– Are you using the Regenerate Thumbnails plugin?
– Did you add any custom image sizes (in PHP or through a plugin?)
– What is the exact PHP code or configuration you used to create the image size? (If you created any)

Thanks!

Closing due to no response.

Apologies for the delay; shortly after posting I went through all manner of life events (graduating, moving to first job, marrying/honeymooning) and just recently got back so you can expect much more prompt replies.

With regard to you questions:
– Which theme are you running?
Newspaper 4.6.3 by tagDiv
– Are you using the Regenerate Thumbnails plugin?
Yes
– Did you add any custom image sizes (in PHP or through a plugin?)
Nope, not to my knowledge
– What is the exact PHP code or configuration you used to create the image size? (If you created any)
I just use WordPress’ stock Media>Add New>(Browse and select image) The code in question that’s erroring out however:

For
Warning: imagecreatetruecolor(): Invalid image dimensions in […]/public_html/wp-includes/media.php on line 2108

Lines 2107 through 2114:

function wp_imagecreatetruecolor($width, $height) {
	$img = imagecreatetruecolor($width, $height); //The line in question
	if ( is_resource($img) && function_exists('imagealphablending') && function_exists('imagesavealpha') ) {
		imagealphablending($img, false);
		imagesavealpha($img, true);
	}
	return $img;
}

Thanks for the detailed report AwagnerA, and congrats on all the finer things in life. ??

Will check this and get back to you shortly.

Hey AwagnerA,

Could you try to see if version 1.1 of the plugin makes the messages disappear?

Since Newspaper is a paid theme I am not able to test the plugin against it, but you could try temporarily disabling the theme and see if that makes the errors go away. In such case you could try contacting the theme author.

Changed to 2014 theme, and the messages went away so it looks like the theme doesn’t play nicely with your plug-in. I’ll file a bug report n their support forums and see what happens.
