c# - How can I get BitmapSource from Image -


i need system.windows.media.imaging.bitmapsource system.drawing.image.

i need make softwarebitmap image. use filestream create bitmapsource.

private static unsafe softwarebitmap getsoftwarebitmap(string filename) {   filestream file = file.open(filename, filemode.open);   bitmapsource bitmapsource = bitmapdecoder.create(file,    bitmapcreateoptions.none, bitmapcacheoption.onload).frames[0];    writeablebitmap writeablebitmap = new writeablebitmap(bitmapsource);   writeablebitmap.lock();   byte[] pixels = new byte[writeablebitmap.pixelwidth *      writeablebitmap.pixelheight * 4];    byte* pbuf = (byte*)writeablebitmap.backbuffer;   (int = 0; < pixels.length; i++)   {     pixels[i] = *pbuf++;   }   var ibuffer = pixels.asbuffer();   writeablebitmap.unlock();    softwarebitmap softwarebitmap = new      softwarebitmap(bitmappixelformat.bgra8, writeablebitmap.pixelwidth,     writeablebitmap.pixelheight);    softwarebitmap.copyfrombuffer(ibuffer);   return softwarebitmap; }

i need function take system.drawing.image instead of path(filename) , instead.

private static unsafe softwarebitmap getsoftwarebitmap(image image) {   bitmapsource bitmapsource = fromimagesomehow(image);    // rest stays same.   ...    return softwarebitmap; }

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
