java - How to add background image to docx document through apache poi? -

-

how can add background image docx document through apache poi or other java framework. have xml block, defined background, in result document that

<w:document xmlns:wpc="http://schemas.microsoft.com/office/word/2010/wordprocessingcanvas" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:r="http://schemas.openxmlformats.org/officedocument/2006/relationships" xmlns:m="http://schemas.openxmlformats.org/officedocument/2006/math" xmlns:v="urn:schemas-microsoft-com:vml" xmlns:wp14="http://schemas.microsoft.com/office/word/2010/wordprocessingdrawing" xmlns:wp="http://schemas.openxmlformats.org/drawingml/2006/wordprocessingdrawing" xmlns:w10="urn:schemas-microsoft-com:office:word" xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main" xmlns:w14="http://schemas.microsoft.com/office/word/2010/wordml" xmlns:w15="http://schemas.microsoft.com/office/word/2012/wordml" xmlns:wpg="http://schemas.microsoft.com/office/word/2010/wordprocessinggroup" xmlns:wpi="http://schemas.microsoft.com/office/word/2010/wordprocessingink" xmlns:wne="http://schemas.microsoft.com/office/word/2006/wordml" xmlns:wps="http://schemas.microsoft.com/office/word/2010/wordprocessingshape" mc:ignorable="w14 w15 wp14"> <w:background w:color="ffffff">     <v:background id="_x0000_s1025" o:bwmode="white" o:targetscreensize="1024,768">         <v:fill r:id="rid2" o:title="alien 1" recolor="t" type="frame"/>     </v:background> </w:background> <w:body>       ..... </w:body></w:document>

assuming want add background element root of document, you'll need like:

xwpfdocument doc = new xwpfdocument(opcpackage.open("test.docx")); if (doc.getdocument().getbackground() == null) {    doc.getdocument.addnewbackground(); };  ctbackground bkgnd = doc.getdocument().getbackground(); bkgnd.setcolor("ffffff");

now, add new background backgrounds list, in different namespace, it's bit trickier. we'd like:

string xml =    "<v:background id=\"_x0000_s1025\" o:bwmode=\"white\" o:targetscreensize=\"1024,768\">" +   "<v:fill r:id=\"rid2\" o:title=\"alien 1\" recolor=\"t\" type=\"frame\"/>" +   "</v:background>"; bkgnd.set(xmltoken.factory.parse(xml));

if in xwpfrun you'll see example of adding in xml different namespace. in .docx namespace ct objects, sadly yours complicated case...

if manual xml stuff bit fiddly you, try using poi process file added in word, , play around ctbackground object. might let work out xmlbeans object inner v:background xml, offer simpler way of doing it. if working, send in patch poi!

java - Copying object fields -

-
what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

c++ - Clear the memory after returning a vector in a function -

-
i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
