Ngokugxilwa kwesandla, ukwandiswa kungatshintshwa ngokuqhubekayo.
Gqibezela umlinganiselo wejometri (umlinganiselo wamanqaku amaninzi kumanqaku, imigca, izangqa, ii-arcs, ii-rectangles, i-grooves, ukuphuculwa kokulinganisa ukuchaneka, njl.).
Umphetho ozenzekelayo wokufumana umsebenzi womfanekiso kunye noluhlu lwezixhobo ezinamandla zokulinganisa umfanekiso zenza lula inkqubo yokulinganisa kwaye zenze umlinganiselo ube lula kwaye usebenze ngakumbi.
Ukuxhasa umlinganiso onamandla, umsebenzi wokwakha ofanelekileyo kunye nokhawulezayo we-pixel, abasebenzisi banokwakha amanqaku, imigca, izangqa, ii-arcs, uxande, iigrooves, imigama, ukuhlangana, ii-engile, ii-midpoints, i-midlines, i-verticals, ukuhambelana kunye nobubanzi ngokucofa ngokulula imizobo.
