Usage
Copy codeThe Code is as follows:
Include 'upimages. class. php ';
$ Max = "upload"; // File upload path
$ Mix = "small"; // thumbnail path (must be created under upload)
$ Mark = "mark"; // path for storing watermarked Images
$ Text = array ("oktang", "2012"); // watermark content
$ Img = new UpImages ($ max, $ mix, $ max); // instantiate a Class Object
$ Photo = $ img-> upLoad ("file"); // uploaded file domain
$ Img-> maxWidth = $ img-> maxHeight = 600; // set height, width, and
$ Img-> toFile = true;
$ NewSmallImg = $ img-> smallImg ($ photo );
$ NewMark = $ img-> waterMark ($ photo, $ text );
Echo $ newSmallImg;
Echo $ newMark;
Echo " <br> ";
Echo " <br> ";

Note that there is a font file, which can be downloaded from the Internet.
