Cropping

[Iziquiel]

I read a lot on the forum about cropping images, and i can´t do it work.
I want to make the thumbnails square, without using exact dimensions, so they don´t get pixeled.
I know that to make square thumbnails, i need to cut part of the thumbnails. How can i do this?
Thanks in advance.

The modpack offers the possibility to crop thumbs. Cropping means using exact dimensions. The parts that don't fit into this exact dimension get cut away (crop).

Better thumbs... (default off)
In config under 'Thumb Sharpening' and 'Files and thumbnails settings'
To crop your thumbnails you'll have to set 'Files and thumbnails settings '-> Use dimension ( width or height or Max aspect for thumbnail ) to 'exact'. Below enter your desired thumb width/ height. Now all thumbnails have the exact same size.
'Thumb Sharpening' works similar to Photoshop unsharpen mask. To learn more about it please search the web. I've preset decent values. To get even sharper thumbs increase 'Amount' to 100-150
