decode

问题 I'm using HTML5 technology with the FileApi. My problem is very simple, but i'm searching since 2 days ago and I have not find anything on the web I have a DicomFile. I use the FileApi from HTML5 to break it down, and get all the information. Finally I get the image data in a byte array. The problem is that I can not decode a JPEG2000 Image and show it in the browser (Chrome, FireFox, any). For example, if the image data is coded in JPEG format, I have no problem at all to show the image in

问题 I am looking for a .NET library that is able to decode data from a PDF-417 barcode that is embedded either in an image file or PDF. At this point, I have only been able to find a Java version and a C version. Ideally, this library would be both open-source and free of charge, but I doubt such a decoder exists. I am open to trying out demos of existing products that you may have had experience with - which leads me to the question - have you had any experience reading PDF-417 barcodes embedded

问题 I am getting one JWT encoded access token from my API in response. But I am not able to decode it and get it in JSON format. I tried using the angular2-jwt library for it, but it did not worked. I am writing my code below: setXAuthorizationToken(client){ let requestHeader = new Headers(); requestHeader.append('Content-Type', 'application/x-www-form-urlencoded'); this.http.post(client.clientURL + "oauth/token", 'grant_type=password&client_id=toto&client_secret=sec&' + 'username=' + client

问题 I am decoding characters in a URL by using HTTPUtility.URLDecode. Here are the characters I have to decode: %26 = "&" %28 = "(" %29 = ")" %20 = " " %5B = "[" %5D = "]" %2C = "," %23 = "#" %F3 = "ó" (spanish character) HTTPUtility.URLDecode works great on all but the last one. I am doing a find/replace on that last character right now, but hoping there is a better automatic way so I don't have to update the find/replace in the future. 回答1: You should use an overload of HttpUtility.UrlDecode()

问题 I want to decode this code. I have no idea what it is, except that it is some kind of code. Can someone help me please? <?php if (!function_exists("T7FC56270E7A70FA81A5935B72EACBE29")) { function T7FC56270E7A70FA81A5935B72EACBE29($TF186217753C37B9B9F958D906208506E) { $TF186217753C37B9B9F958D906208506E = base64_decode($TF186217753C37B9B9F958D906208506E); $T7FC56270E7A70FA81A5935B72EACBE29 = 0; $T9D5ED678FE57BCCA610140957AFAB571 = 0; $T0D61F8370CAD1D412F80B84D143E1257 = 0;

问题 I am looking for a way to decode quoted-printables. The quoted-printables are for arabic characters and look like this: =D8=B3=D8=B9=D8=A7=D8=AF I need to convert it to a string, and store it or display.. I've seen post on stackoverflow for the other way around (encoding), but couldn't find decoding. 回答1: Uhm, it's a little hacky but you could replace the = characters with a % character and use NSString's stringByReplacingPercentEscapesUsingEncoding: method. Otherwise, you could essentially

问题 I want to decode an image from the SD card with BitmapFactory.decodeFile(path, options). I also want images that are larger than 2048x2048 pixels to be scaled down to at most 2048x2048 (maintaining the proportions). I could do this manually after getting the bitmap, but that would require allocating a large amount of bytes in addition to the ones already allocated. How should i set up my BitmapFactory.Options object to get that effect? Thanks 回答1: Use BitmapFactory.Options.inSampleSize when
