Online image editor

Glavni zadatak ovog završnog rada bio je opisati izradu web stranice koja ima mogućnost učitavanja i obradu slike. Pod obradu se misli na podešavanje kontrasta, svjetline i saturacije slike te mogućnost mijenjanja veličine slike, rotacije i rezanja slike. Sam proces izrade se sastoji iz pisanja HTML i CSS koda za izgled stranice te pisanja JavaScript koda za samu obradu slike. Jezici su objašnjeni tim redom kako bi se stavio naglasak na redoslijed pisanja koda koji nije nebitan u izradi stranice. Najbolje je prvo napisati kod za izgled stranice u HTML-u i CSS-u te vidjeti rezultate na nekom od internet preglednika, a zatim pisati kod potreban za funkcionalnost stranice. Kod za funkcionalnost mora stvoriti mogućnost učitavanja slike na stranicu kao i mogućnost mijenjanja efekata spomenutih na početku ovoga teksta. Web stranice za obradu slike postaju sve popularnije i traženije iz razloga što nije potrebno prethodno instalirati program za obradu već jednostavno se posjeti stranica, učita željena slika i krene sa radom. Jednostavne su za korištenje i nije potrebno imati iskustvo u radu sa programima takvoga tipa. Jedino što je potrebno imati vezu sa Internetom, iako u današnje vrijeme se to ne smatra nekakvim luksuzom.The main task of this paper was to describe the making of a web page which has the possibility of loading and editing pictures. By editing we mean adjusting the contrast, saturation and brightness of a picture as well as changing the size of a picture, rotating and cropping a picture. The very process of developing consists of writing HTML and CSS code for the look of a page and writing JavaScript code for editing purposes. Languages are explained in that particular order to put importance on the order of writing the code which isn't inessential when it comes to it. It is best to write the HTML and CSS code first, see the result of our code and then write the code necessary for the functionality of the page. Code necessary for the functionality needs to create the possibility of uploading a picture on the page as well as the possibility to modify the effects of the picture mentioned at the beginning of this text. Web pages for picture editing are becoming more and more popular and wanted because we dont need to install a program for editing. We just simply can visit a page, upload our picture and start editing. They are very simple to use and having experience in this sort of work isn't neccesary. We only need an Internet connection of some sort, altough having one isn't considered a luxury
