Description

Hello,

is there a way to pad an image if it's smaller than required dimensions?

For example:

desired dimensions actual dimensions expected result
1000x1000 200x200 1000x1000 image with 200x200 centered inside
300x300 350x350 downscaled to 300x300

Original original

Desired output large

Contributor guide

Research direction
Implement a new option in the resize function to add padding when the source image is smaller than the target dimensions. Refer to libvips's 'gravity' and 'extend' operations to add a border.
