Go package for fast high-level image processing powered by libvips C library
Extend
option value and send it to lipvips this will change the default from the one that lipvips use which is background
to the ones that bimg use which is C.VIPS_EXTEND_BLACK
but because the lip add extra 1 or .5 pix the background is considered black anyway so this will not affect anyone but will fix the bug of having border on the right and bottom of some images
