Has anyone got any better ideas about how to detect what version of GD is
running other than the following. The reason I ask is that I want to use
imagecopyresampled() only if available ie. GD >= v2.0.
OPTION 1.
Parse phpinfo() output for the GD version info. Expensive.
OPTION 2.
Run imagecopyresampled() suppressing errors and then check the error msg.
ie:
@imagecopyresampled();
if ($php_errormsg != "imagecopyresampled(): requires GD 2.0 or later")
// GD >= v2.0
} else {
// GD < v2.0
}
Option 2 is the best I can come up with at the moment.... luckily the
"requires GD 2.0" error message is triggered before the argument validation
errors.
Anyone got a better idea?
Thanks,
