Description

Howdy,

I've stubled upon weird behaviour in TYPO3 which seems to strip/crop out transparent areas around an image which results in the processed image being smaller as the transparent parts seem to be stripped.

Steps to reproduce:
1) Filelist module > Upload th image original-file.png (see attached; note the transparent outline in the image)
2) Page > create element (images only) > use the uploaded file
3) Image will be rendered without the transparent area around (see stripped-transparency-result.png)

Anyone else has experienced this issue?

Thank you!

ps. TYPO3 8.6.1 using GraphicsMagick.
