Hello I’m somewhat stuck with a feature of my website I want to upgrade from Kirby 2 to v3.
I’m a photographer and I have a built in client release form inside any of my clients gallery. The idea is, that I make an selection of images I want to release to the public and the client can login and edit this selection and finally fill out a release form, which will generate a pdf contract. This is where I’m stuck.
The form is posting to the corresponding controller, which handles form submission an loads up the HTML2PDF library (https://html2pdf.fr) for generating the pdf. The pdf contains the form inputs as well as the selected images listed in columns.
How I did it in v2
Since pasting the thumb url as image source inside the pdf generation seemed to be way to slow (talking about 60 to 200 pictures), I switched to using the dataUri function in Kirby 2 which worked perfectly.
thumb($selectedimage, array('width' => 300,'height' => 300, 'crop' => false, 'quality' => 40))->dataUri()
This has been deprecated in v3 so I used the Toolkits pendants
F::base64()) with the root path of the thumbnail. Unfortunately, the thumb is not yet created when trying to encode it to base64, returning an empty string.
What I’m trying out now
$thumb = $selectedimage->thumb(['width' => 200,'height' => 200, 'crop' => false, 'quality' => 40]);
$thumb->url() does work when opening it with the browser or importing it in pdf (but is very slow)
dump(file_get_contents($thumb->root())); Returning error file not found
dump(F::uri($thumb->root())); returning empty base64 string
Is there a way I can get the source of the thumbnail in base64 encoding or force-generate those thumbnails?
Thanks in advance!
