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);

                    Quarter-circle Tiles

                    Image
                    up vote 0 down vote favorite I have $99$ identical square tiles, each with a quarter-circle drawn on it like this: [asy] size(1.5cm); draw(Arc((2,0),1,90,180),red+1); draw((0,0)--(2,0)--(2,2)--(0,2)--(0,0)); [/asy] When I arrange the tiles in a $9times 11$ rectangular grid, each with a random orientation, what is the expected value of the number of full circles I form? I think this problem has to do with finding the chance any given 2x2 square has a circle, but I can't find it. expected-value share | cite | improve this question asked Nov 20 at 15:03 6minecraftninja 1 2

                    0 I think it's similiar to NFAs. I replace the finite states of the given automaton for start-states for my new automaton. I do it with $epsilon$ -transition from the start state to the actual finite states of the given automaton. The start state of the given automaton will be my accepting(finite) state of my new one. All transitions will be reversed of course to recognize the reversed word. But how do I have to change the stack of the pushdown automaton? That's tricky. formal-languages automata context-free-grammar share | cite | improve this question edited Nov 29 '18 at 14:20 joee
