Abstract [sv]

Fler och fler webbapplikationer låter sina användare ladda upp bilder. Ibland behöver dessa bilder manipuleras på något sätt, till exempel förminskas eller beskäras för att bättre passa in på webbsidan. Detta kan göras på flera olika sätt men denna rapport behandlar endast ett av biblioteken för bildmanipulation i PHP, nämligen GD-biblioteket.Syftet med denna rapport var att hitta eventuella styrkor och svagheter i detta bibliotek gällande bildmanipulation. Detta har gjorts genom att försöka skapa, för webben vanlig funktionalitet så som exempelvis tumnaglar, beskärning och vattenmärkning och sedan dokumentera resultatet.Resultatet av testningen visade att all testad funktionalitet gick att åstadkomma och slutsatsen som drogs av detta var att GD-biblioteket är ett bra val för någon som vill manipulera bilder.
