Scaling of picture files in Java

The image needs to be processed so that it can be properly displayed in the picture. After finding some information, processing is also simpler: * * Andychen (andy.chen.sh@gmail.com) * **/public static Icon Getfixedboundicon (String filePath, int h eight, int width) throws exception{double ratio=0.0;//zoom ratio file F = new file (FilePath); if (! F.isfile ()) throw new Exception (f+ "is not-image file error in getfixedboundicon!"); ICON ret = new ImageIcon (FilePath); BufferedImage Bi = Imageio.read (F); if ((Bi.getheight () >height) | | (Bi.getwidth () >width)) {if (Bi.getheight () >bi.getwidth ()) {Ratio = (new Integer (height)). Doublevalue ()/bi.getheight ();} else {Ratio = (new Integer (width)). Doublevalue ()/bi.getwidth (); The file ThF = new File (filepath+ "_" +height + "_" +width); Image itemp = bi.getscaledinstance (Width,height,bi.scale_smooth); Affinetransformop op = new Affinetransformop (Affinetransform.getscaleinstance (Ratio, Ratio), NULL); itemp = Op.filter (Bi, NULL); try {imageio.write (bufferedimage) itemp, "JPG", ThF); ret = new ImageIcon (Thf.getpath ());} catch (Exception ex) {}} RetuRN ret; }
