bytearray

问题 This is in reference to: byte[] and efficiently passing by reference And the SqlDataReader found in this post: Getting binary data using SqlDataReader Inside a loop, I'm calling a database and returning a large object ( varbinary[max] ). Currently, I'm running into OutOfMemory exceptions, so I'm trying to reduce the footprint in the Large Object Heap (LOH). So, I'm creating a byte array for the largest file that I'd download and adding some padding just in case. For instance: byte[]

问题 I successful store image in database BLOB format. DataType for image in webservices model class is byte []. My web services: @POST @Consumes("application/json") @Produces("application/json") @Path("login") public Korisnici Login(Korisnici k) { Korisnici exception = new Korisnici(); ............ Json webservice example: [ { "id": 2, "ime": "haris", "mjestoGoogleMaps": null, "password": "1234", "username": "haris", "image": "iVBORw0KGgoAAAANSUhEUgAizDMizDMizDMizDMizDMizDMizDMizDMizDMizDMiz/JPL

问题 I am using following code to get the images of a logo and save it in the database. DefaultHttpClient mHttpClient = new DefaultHttpClient(); HttpGet mHttpGet; HttpResponse mHttpResponse; HttpEntity entity; for (int reportsCount = 0; reportsCount < reportsArr.length; reportsCount++) { //Make a request to get our image mHttpGet = new HttpGet(reportsArr[reportsCount][1]); byte[] categoryLogoArr = null; try { mHttpResponse = mHttpClient.execute(mHttpGet); if (mHttpResponse.getStatusLine()

问题 How do I send multiple jpg files, as byte arrays, to my mySQL database with C#? I have read and understand how to convert image files to byte arrays, but I can only figure out how to use that method for a single image to mySQL as a blob. My application requires the user to upload at least 2 image files and allows up to 10, while sending information from multiple textBox. I tried creating an array of byte arrays, but that didn't work. When I'd reference that array at a specific index during

问题 I already saw post at Delphi XE4 Indy compatibility issue between TBytes and TidBytes about compatibility issues between the data types tbytes and tidbytes. From the second answer I learned, that it looks like they can't be used together even though they're both array of byte. However, the latest answer says, that in indy 10.5.9 it was dependent of the presence of TBytes, and that only in Indy 10.6 was it completely submitted as array of byte. Anyway,I have a .pas unit which decodes several

问题 I have written one application for image processing in Java. I have processed the image which is the buffered image and now I want to return the byte[] for that processed image that is I should get the byte array of binarized image. Here is my code: public static byte[][] binarizeImage(BufferedImage bfImage){ int red; int newPixel; int h ; int w ; int threshold = otsuTreshold(bfImage); // this function returns the threshold value 199 BufferedImage binarized = new BufferedImage(bfImage

问题 I'd like to use an array initializer to build one byte array out of another byte array as well as some other bytes that form a header/trailer. Basically, I'd like to do something like this: byte[] DecorateByteArray(byte[] payload) { return new byte[] { 0, 1, 2, payload.GetBytes(), 3, 4, 5}; } GetBytes() above is fictional, unfortunately. Is there any nice/elegant way to do this? I solved this by using a BinaryWriter to write everything to a MemoryStream , and then converting this into a byte

问题 I am receiving jpg image through socket and it is sent as ByteBuffer what I am doing is: ByteBuffer receivedData ; // Image bytes byte[] imageBytes = new byte[0]; // fill in received data buffer with data receivedData= DecodeData.mReceivingBuffer; // Convert ByteByffer into bytes imageBytes = receivedData.array(); ////////////// // Show image ////////////// final Bitmap bitmap = BitmapFactory.decodeByteArray(imageBytes,0,imageBytes.length); showImage(bitmap1); But what is happening that it

问题 Does anyone knows how to do this? Is this even possible? I've read about decode and encode but since I'm not an expert I don't know if it will help. 回答1: Of course, it is possible. If you have the byte array my @bytes = (0xce, 0xb1, 0xce, 0xb2, 0xce, 0xb3); you need to first combine those into a string of octets: my $x = join '', map chr, @bytes; Then, you can use utf8::decode to convert that to UTF-8 in place : utf8::decode($x) or die "Failed to decode UTF-8"; You can also use Encode::decode
