ERROR: Uncaught exception 'ImagickException' with message 'Invalid image geometry'

Question

I made a small code for resizing images present on my server. I am testing it on xampp. Here it is:

if ($img_width[0] >= 750) { $imagick_image_width = 920; }
elseif (($img_width[0] > 500) && ($img_width[0] < 750))  { $imagick_image_width = 500; }
elseif (($img_width[0] >= 200) && ($img_width[0] <= 500)) { $imagick_image_width = 500; }

$save_path = 'c:/xampp/htdocs/images/'.$image_name.'.jpg';

$image = new Imagick($save_path);
$image->resizeImage($imagick_image_width, 0,Imagick::FILTER_LANCZOS,0.95); //line 226
$image->writeImage($save_path);
$image->destroy();  

I have taken img_width via getimagesize array.

When executed this gives error:

Fatal error: Uncaught exception 'ImagickException' with message 'Invalid image geometry' in C:\xampp\htdocs\test-templ.php on line 226

ImagickException: Invalid image geometry in C:\xampp\htdocs\test-templ.php on line 226

How to resolve this?

Answer 1

The bestfit parameter is poorly documented. You need to set it to false if you set one of the dimensions to 0.

If bestfit=false and height=0 then a proportional height will be calculated by imagemagick. If bestfit=true and height=0 you will get the "Invalid image geometry" error.

bestfit=true should only be used when both width and height are specified, and it will adjust one dimension to keep the aspect ratio consistent.
