I have an issue with Nette\Utils\Image::crop and underlying imagecrop(). I was not able to preserve PNG transparency when using either of them. No solution I found online worked. When I crop “manually” (like in https://api.nette.org/…age.php.html#396), the transparency is preserved.
- nette/utils v2.4.8
- GD library Version 2.2.5, GD headers Version 2.2.3, libPNG Version 1.2.54
- PHP 7.1.9 (7.1.9–1+ubuntu16.04.1+deb.sury.org+1)
- Is it somehow possible to keep the transparency when using imagecrop()?
- Should Nette\Utils\Image::crop preserve transparency (either with imagecrop or using the old version)? If yes, I would be happy to prepare a pull request.
EDIT: This issue is also related to using Nette\Utils\Image::resize with the EXACT flag as it creates and immediately crops the image (without a way to manipulate it before cropping).

so, have you found answers to your questions? maybe there's someone who can chime in? please update or answer anybody! thanks a lot in advance!
Hi, I got no answers to the original problem, so I guess the solution is to avoid Image::crop and using the “else branch” of it (https://api.nette.org/…age.php.html#393) instead.
I ended up not using crop directly anyway, because i needed 1) white instead of transparent background 2) the ability to create “cutouts” bigger than the original image (like a square containg the whole wide picture).
