Thanks for the report, but this extension as not been tested with PHP 7. The error is pretty weird tho, since your PHP setup seems ok. Do other image format works ?

[nonozone]

I donot use other image format,so i dont know it.

[nitriques]

Can you try a png just to see if it works ?

[nonozone]

OK，I found the problem. Just use the mode 1：resize have this problem. Other mode, running normally

[nitriques]

Very, very weird.
