java - How to save an image in a set location? -


i trying save resized picture user's desktop not sure how that.

here's code far:

mi.addactionlistener(new actionlistener() {         @override         public void actionperformed(actionevent e) {             string userhome = system.getproperty("user.home");             filechooser = new jfilechooser(userhome + "\\desktop");             filechooser.setautoscrolls(true);             switch (filechooser.showopendialog(f)) {             case jfilechooser.approve_option:                 bufferedimage img = null;                 try {                     img = imageio.read(filechooser.getselectedfile());                 } catch (ioexception e1) {                     e1.printstacktrace();                 }                 image dimg = img.getscaledinstance(f.getwidth(),                         f.getheight(), image.scale_smooth);                  path = new imageicon(dimg);                 configprops.setproperty("path", filechooser                         .getselectedfile().getpath());                 imbg.seticon(path);                  break;             }         }     });

the code above resizes imaged selected fit size of jframe sets jlabel.

this works want output file set location lets users desktop make easier. i'm looking @ output stream can't quite head around it.

any great.

get current icon jlabel...

icon icon = imgbg.geticon();

paint icon bufferedimage...

bufferedimage img = new bufferedimage(icon.geticonwidth(), icon.geticonheight(), bufferedimage.type_int_argb); graphics2d g2d = img.creategraphics(); icon.painticon(null, g2d, 0, 0); g2d.dispose();

save image file...

imageio.write(img, "png", new file("resizedicon.png"));

(and yes, use jfilechooser pick file location/name)

you should take @ this better examples of scaling image, way, scale bufferedimage bufferedimage , save hassle of having re-paint icon

you might take @ writing/saving image

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
