hi all - 'newbee' here
does anyone know of any image editing software
that has options for tools such as 'fuzzy-select' ('magic-wand') and 'flood-fill'
whereby corner-neighbour ('8-connected') pixels can be included
in addition to the usual edge-neighbour ('4-connected') pixels
so that - for example
a straight uniform-colour one-pixel-width diagonal line could be fuzzy-selected (or flood-filled) in a single click
thank you for any help you may be able to offer :-)
