Watermarks and text for Android Images

Two methods: 1. directly write the text string STR = "Text to be written by PICC"; imageview image = (imageview) This. findviewbyid (R. id. imageview); bitmap photo = bitmapfactory. decoderesource (this. getresources (), R. drawable. text); int width = photo. getwidth (), hight = photo. getheight (); system. out. println ("width" + width + "height" + hight); icon = bitmap. createbitmap (width, hight, bitmap. config. argb_8888); // create an empty bitmap canvas = new canvas (ICO N); // initialize the image drawn from the canvas to the icon. Paint photopaint = new paint (); // create a paint brush photopaint. setdither (true); // obtain the image with clear sampling photopaint. setfilterbitmap (true); // filter some rect src = new rect (0, 0, photo. getwidth (), photo. getheight (); // create the coordinates rect DST = new rect (0, 0, width, hight) of a specified new rectangle ); // create a coordinate canvas for the specified new rectangle. drawbitmap (photo, SRC, DST, photopaint); // scale photo or expand to the fill area used by DST. photopaint paint textpaint = new paint (paint. anti _ Alias_flag | paint. dev_kern_text_flag); // sets the paint brush textpaint. settextsize (20366f); // font size textpaint. settypeface (typeface. default_bold); // use the default width textpaint. setcolor (color. red); // used color // textpaint. setshadowlayer (3f, 1, 1, this. getresources (). getcolor (Android. r. color. background_dark); // specifies the canvas for audio and video settings. drawtext (STR, 20, 26, textpaint); // draw up the word, start to unknown x, y uses that pen to draw the canvas. save (canvas. all_save_flag); canvas. restore (); Im Age. setimagebitmap (icon); savemybitmap (icon); 2. combine the two images into the oncreat method {bitmap mark = bitmapfactory. decoderesource (this. getresources (), R. drawable. icon); bitmap photo = bitmapfactory. decoderesource (this. getresources (), R. drawable. text); bitmap A = createbitmap (photo, mark); image. setimagebitmap (a); savemybitmap (a);} private bitmap createbitmap (Bitmap SRC, bitmap watermark) {string tag = "createbit Map "; // log. D (TAG, "Create a New bitmap"); If (src = NULL) {return NULL;} int W = SRC. getwidth (); int H = SRC. getheight (); int WW = watermark. getwidth (); int wh = watermark. getheight (); // create the new blank Bitmap bitmap newb = bitmap. createbitmap (W, H, config. argb_8888); // create a new bitmap canvas CV = new canvas (NEWB) with the same width as SRC; // draw SRC into cv. drawbitmap (SRC, 0, 0, null); // you can specify SRC // draw watermark into cv. drawbitmap (watermark, W-ww + 5, H-Wh + 5, null); // Add the watermark to the bottom right corner of SRC // save all clip cv. save (canvas. all_save_flag); // save // store cv. restore (); // store return newb;} // Save the image to public void savemybitmap (bitmap BMP) under data {fileoutputstream Fos = NULL; try {Fos = openfileoutput ("image1.jpg", context. mode_private); BMP. compress (bitmap. compressformat. JPEG, 100, FOS);} catch (Fi Lenotfoundexception e) {}finally {If (FOS! = NULL) {try {FOS. Flush (); FOS. Close () ;}catch (ioexception e ){}}}}
