Likely memory leak

```
It looks like the Poppler::Page object isn't getting cleaned up in the GetImage 
function?  Would need something like:

                memcpy(p, pngData.data(), pngData.length());
                delete page;  // Need to delete the page!
                return retVal;

Cheers,

Andrew
