Spletni urejevalnik slik

PAJK, SAMO (author), Kavčič, Alenka (mentor)

S slikami beležimo spomine, trenutke, dogodke in delimo stvari, ki nas zanimajo. V današnjem času se velikokrat zgodi, da je potrebno kakšno sliko tudi obdelati, urediti ali pa dodati kakšen umetniški učinek, a pri roki nikoli nimamo urejevalnika, ki bi nam to omogočal. Zato je bil izdelan spletni urejevalnik slik, ki uporabnikom nudi hitro in učinkovito urejanje slik s katerega koli računalnika. Naloga opisuje izdelavo urejevalnika slik na spletu in njegovo implementacijo s tehnologijo WebGL za hitrejše ter bolšje delovanje aplikacije. V ta namen je izdelana knjižnica za lažje delo s programskim vmesnikom WebGL, ki je kasneje uporabljena pri izdelavi aplikacije. Opisana je arhitektura aplikacije in glavne podatkovne strukture, ki jih obdelujejo orodja, s pomočjo katerih lahko spreminjamo, dodajamo in urejamo slikovne elemente. Implementiranih je nekaj preprostih orodij, ki se pogosto uporabljajo v tovrstnih aplikacijah ter končnemu uporabniku omogočajo spreminjanje in urejanje slik.

Abstract

Images are made every day to keep memories, moments and share things we like. Individuals need to edit, change or add an artistic touch to a photo many times, but they can't seem to find an image editing application in order to do it. A web based image editing application was created for that purpose so that we can use it on any computer in order to quickly and effectively edit photos. The thesis describes the implementation of a web based image editing application with technology WebGL, which was used for better and faster image processing. The main topic of the paper describes the creation of a simple library for easier interaction with WebGL, which serves as a base for implementing the main part of the application. After basics are covered, the application architecture and data structures are described and the tools that manipulate those data structures are presented. With the help of implemented tools the user can change and edit images inside the browser.
