Create styled image programmatically











up vote

favorite












I have a module that create custom PDF with multiple selected nodes and I use the below function to create the link to styled images:



$file = File::load($img_id);

$imagesPath = ImageStyle::load('550x300')->buildUrl($file->uri->value);


Unfortunately, the image itself is not created, only the link, which is ok if I display it on a simple webpage because Drupal will create it on the fly when needed but on a PDF it cause errors because the image it not found before the PDF could be displayed.



Is there a programmatically way to create this image ?



Thanks.

          You need to execute createDerivative() on ImageStyle. 



          $image_style = ImageStyle::load('550x300');
          

          
$file = File::load($img_id);
          
$image_uri = $file->getFileUri();
          
$destination = $image_style->buildUrl($file->uri->value);
          
$image_style->createDerivative($image_uri, $destination);


          Docs: https://api.drupal.org/api/drupal/core%21modules%21image%21src%21Entity%21ImageStyle.php/function/ImageStyle%3A%3AcreateDerivative/8.6.x

                    0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?
