Set an offset from gravity centre
Posted: 2017-02-25T05:23:37-07:00
Hi,
I'm trying to include a conditional offset to the gravity centre of my text on my generated image. I've done some reading and apparently I can use geometry.
Here is the code:
This is the code I tried to use:
Which in theory should offset the text from the gravity center, however when I try it it stops my image generating. I think I have made a mistake because the only example code I can find is for the command line, not for the php interface.
Any help would be appreciated.
EDIT - I'm coming to the conclusion that this option exists in the command line interface but not in the PHP API?

$draw->setFillColor($textColor);
$draw->setFontSize( 25 );
$draw->setGravity(Imagick::GRAVITY_CENTER );
//$draw->setGeometry(Imagick::Geometry +20 +20); --New code that doesn't work
$image->annotateImage($draw, 0, 0, 0, $inputdata);
$gradient->compositeImage($image, Imagick::COMPOSITE_OVER, 0, 0);
$gradient->setImageFormat('png');
header('Content-type: image/png');
echo $gradient;
return;
}
