Java implementation of tilt watermark full picture _java

Today encountered a demand for the upload map covered with watermarks, on the internet to find a long time is set in the specified location watermark, the following code is I find the code online, and then transformed into. Let's look at the effect chart first.

Here's how to implement it:
The first step: the use of PS or beauty map software design watermark images, such as:

Step two: Put the following code into the class:

Package org.platform.framework.commons.util;
Import Java.awt.AlphaComposite;
Import Java.awt.Color;
Import Java.awt.Font;
Import Java.awt.Graphics2D;
Import Java.awt.Image;
Import java.awt.RenderingHints;
Import Java.awt.image.BufferedImage;
Import Java.io.File;
Import Java.io.FileOutputStream;
Import Java.io.InputStream;

Import Java.io.OutputStream;
Import Javax.imageio.ImageIO;

Import Javax.swing.ImageIcon;

Import Com.founder.cms.watermark.util.ImageMarkLogoUtil;
 /** * * * * Create watermark */public class Imagemarkutil {/** watermark transparency * * private static float alpha = 0.5f;
 /** watermark Picture Rotation angle * * private static double degree = 0f;

 private static int interval = 0; 
 /** * Set watermark parameters, do not set the default value * * @param alpha * Watermark Transparency * @param degree * watermark Picture Rotation angle * * @param interval * Watermark image interval * * public static void Setimagemarkoptions (float alpha, int degree, int interval) {if (alpha!= 0.0f) {imagemarkutil.al
 PHA = Alpha;
 } if (degree!= 0f) {imagemarkutil.degree = degree; } if (Interval!= 0f) {imagemarkutil.interval = interval;   /** * Add watermark image to Picture * * @param waterimgpath * Watermark Picture Path * @param srcimgpath * source Picture path * @param targerpath *  Target Picture Path */public static void Watermarkbyimg (String waterimgpath, String Srcimgpath, String targerpath) throws Exception
 {watermarkbyimg (Waterimgpath, Srcimgpath, Targerpath, 0); /** * Add watermark image to Picture * * @param waterimgpath * Watermark Picture Path * @param srcimgpath * source Picture path * @param targerpath * target picture Path */public static void Watermarkbyimg (String waterimgpath, String srcimgpath) {try {watermarkbyimg (Waterimgpath, S
 Rcimgpath, Srcimgpath, 0);
 catch (Exception e) {//TODO auto-generated catch block E.printstacktrace (); /** * Add watermark picture to picture, can set watermark picture rotation angle * * @param waterimgpath * Watermark Picture Path * @param srcimgpath * source Picture path * @param targe rpath * Target Picture path * @param degree * watermark Picture Rotation angle * * public static void Watermarkbyimg (String waterimgpath, String srcimg Path, String Targerpath, double degree) throws exception {outputstream OS = null;

 try {Image srcimg = imageio.read (new File (Srcimgpath)); BufferedImage buffimg = new BufferedImage (Srcimg.getwidth (null), srcimg.getheight (null), BUFFEREDIMAGE.TYPE_INT_RGB)

 ;

 1, get the Brush object graphics2d g = Buffimg.creategraphics (); 2, set the jagged edge of the line to handle G.setrenderinghint (Renderinghints.key_interpolation, Renderinghints.value_interpolation_
 bilinear); G.drawimage (srcimg.getscaledinstance (Srcimg.getwidth (null), srcimg. GetHeight (null), Image.scale_smooth), 0, 0, NULL
 ); 3, set the watermark rotation if (0!= degree) {G.rotate (Math.toradians (degree), (double) buffimg.getwidth ()/2, (Double) buffimg. G
 Etheight ()/2);

 ///4, Watermark pictures of the path watermark picture is generally gif or PNG, so that you can set the transparency ImageIcon Imgicon = new ImageIcon (Waterimgpath);
 5, Get Image object.

 Image img = imgicon.getimage ();

 G.setcomposite (Alphacomposite.getinstance (alphacomposite.src_atop, Alpha)); 6, Watermark picture position for (int height = interval + imgicon.geticonheight (); height < buffimg. getheight (); height = HeiGht +interval+ imgicon.geticonheight ()) {for (int weight = interval + imgicon.geticonwidth (); weight < buffimg. get Width (); Weight = weight +interval+ imgicon.geticonwidth ()) {G.drawimage (IMG, Weight-imgicon.geticonwidth (), Height-imgico
 N.geticonheight (), NULL);
 } g.setcomposite (Alphacomposite.getinstance (alphacomposite.src_over));

 7, Release resources G.dispose ();
 8, generate picture OS = new FileOutputStream (Targerpath);

 Imageio.write (buffimg, "JPG", OS);

 System.out.println ("Picture complete add watermark picture");
 catch (Exception e) {e.printstacktrace ();
 Finally {try {if (null!= OS) os.close ();
 catch (Exception e) {e.printstacktrace (); }} public static void Main (string[] args) {System.out.println (".
 Add watermark Picture Start ... ");
 /** * Watermarkpath watermark image address Uploadpath Upload after successful file address///modify Default Parameters//imagemarkutil.setimagemarkoptions (0.0f, 0, 20);
 Imagemarkutil.watermarkbyimg (Watermarkpath, Uploadpath); System.out.println ("..
 Add watermark Picture End ... ");

 }

}

The third step: in the implementation of the successful upload, call the class, such as:

 /**
 * Watermarkpath watermark Image Address
 * Uploadpath upload successful file address *
 *
 imagemarkutil.watermarkbyimg (Watermarkpath, Uploadpath); If you think the watermark interval is too close, you can set the interval by the following code:

//Modify the default parameter
 imagemarkutil.setimagemarkoptions (0.0f, 0,
 );
 Imagemarkutil.watermarkbyimg (Watermarkpath, Uploadpath);

The above is the entire content of this article, I hope to help you learn, but also hope that we support the cloud habitat community.
