I think if you use a MicroSoft account to authenticate that you will find a so-called zumo token (specify a X-ZUMO-AUTH header). Check the Postman Console to ensure that the correct SSL certificate is being sent to. If that doesn’t resolve the issue, your server may be using a client-side SSL connection which you can configure under Postman Settings. Active Directory credentials are never sent with the request, so you will never find them via the Developer Tools. If you’re using HTTPS connections, you can turn off SSL verification under Postman settings. Generate an OAuth 2.0 token: Ensure that the Google APIs are enabled Create an OAuth 2. Now you can do a get call via the browser (posts are not possible) and then you will find out that you still can’t find the security token. Postman will query Google API impersonating a Web Application. The browser redirects you to a login page when you enter the following address: If you switch it on, it’s just the other way around. The server returns a response through the Postman proxy back to the client. The Postman proxy captures the request and forwards the request onward to the server. If you switch Authentication/Authorization off in the Preview Portal, both the client application and Postman work, but the browser doesn’t work. The Postman app listens for any calls made by the client app or device. What I found out is that it makes a difference how you configure Authentication / Authorization for the Web App in the Azure Preview Portal. Then I went to Postman, entered the authorization header and voila: it works! If you do a quickwatch on the client created you actually see the authorization header: I am not sure whether the app setting caused this issue (the credential seems not be sent to server). HttpResponseMessage response = await client.PostAsync(apiBaseAddress + “api/serviceorders”, new StringContent(postBody, Encoding.UTF8, “application/json”)) Yes, as I tested this in chrome app and windows app, I will have the same issue as you (cant work in windows app and work well in chrome app). The relevant code fragment is shown below:ĪuthContext = new AuthenticationContext(authority) ĪuthenticationResult authResult = authContext.AcquireToken(apiResourceId, clientId, redirectUri) Ĭ(new MediaTypeWithQualityHeaderValue(“application/json”)) Ĭ = new AuthenticationHeaderValue(“Bearer”, authResult.AccessToken) Then I developed a custom client to get the token. The idea was to use the so-called Developer Tools to obtain the security token.Īuthorization has been denied for this request. First I tried to access the service via Chrome. We highly recommend using the Postman Desktop app or the Postman Web app to prevent any data loss and to ensure your data is synced.I have been struggling a bit with Azure Active Directory authentication of WebApps. Developer Support Blogs Cisco Security Technology Alliance (CSTA) Partners ISE / NAC Community Videos. Postman does not have the means to recover any data locally that was not synced. If not, it's likely that the data are corrupted. Move the files inside into the existing Extension folder in your machine, located in step 6.

There's nothing in the language itself that prevents this - since, as far as the compiler is concerned, implementing Deque just requires that you define a bunch of methods - there's no enforcement of what these methods are supposed to do. Now for an important albeit somewhat confusing note - LinkedList can, for example, implement Deque and have an addFirst that doesn't do what it's supposed to - it can just, for example, print some random text. Based on the docs, the addFirst function needs to add to the front of the Deque, and indeed, with a LinkedList, it will add to the front of the LinkedList (while the front of the LinkedList doesn't need to be the front of the Deque, by looking at the Deque methods implemented in LinkedList, we see that the front of the Deque is the front of the LinkedList, and all the methods add to / remove from one of the sides, do so from the correct side). Queue doesn't actually need to be FIFO (see the docs) (if it needed to be, a LinkedList would also need to be), so LinkedList would have quite a bit of freedom in this regard, so let's continue this explanation using Deque - it has methods to support addition and removal from either the front or the back.īecause LinkedList implements Deque, it needs to implement the addFirst function. The whole piece of paper is still there - you could simply remove the covering, which would be synonymous to casting it back to a LinkedList, which would then allow you to call any LinkedList method on it again.īy the way a LinkedList "normally would" do things I mentioned above, I mean a LinkedList is always a linked-list, even if you assign it to a Queue - it doesn't suddenly start using an array as the underlying implementation, as an ArrayDeque would (which also implements Queue), or something else. Given that most of it is covered, you can't see it's a LinkedList, all you can see is that it's a Queue, so you can only call the Queue methods on it. If you call a Queue method on it, it will still do things like a LinkedList normally would, since that that's what the piece of paper is. Think of the assignment to a Queue as covering all but a little part of this piece of paper which reveals that it's a Queue. Let us define our class template for the Queue implementation.įront and rear instance variable are the linked list node that holds the data and a reference to the next node.To explain with a (perhaps somewhat flawed) metaphor - think of a LinkedList as a piece of paper. once we remove the tail then there is no way to point to the element that was before a tail in a singly linked list unless we have an extra pointer. Removal of an element happens from the front of the Q and if the linked list tail is the front of a queue then how we going to remove the front element of a Q(the tail of linked list) as the linked list does not allow to remove the tail of it at a constant time O(1). The front of Q is the head and rear of the Q is tail due to the remove operation. You can visit my previous article for custom implementation of linked list in Java. While using linked list for the queue implementation, EnQueue operation is implemented by inserting element at the end of the list and DeQueue operation is implemented by deleting an element from the beginning of the list.
So for example, a single highly compressed JPEG image in your PowerPoint file can easily double in size when it is exported to the PDF and saved using Flate compression. Under certain circumstances some images which are saved as JPEG in the source presentation, are encoded into the PDF using a lossless compression format called Flate when it’s used in PDF files (its official name is Deflate).īeing lossless, Flate retains all of the image information but the downside is that the image size will be a lot bigger. We discovered that the main reason for bloated PDF files created from PowerPoint appears to be due to a little-known limitation of the PDF creator on Mac (“Quartz PDFContext”). Why are some PDF files bigger than PPTX on Mac? So we decided to run some experiments and share the results. On closer investigation we came to realise that something a little odd was going on. They had to compress it again with NXPowerLite before they could email it. They had compressed their PowerPoint file before exporting it to PDF and had been surprised to find the PDF was much larger. We first heard about this from a customer who had been troubled by this problem, and thought it might be an issue with our compression software NXPowerLite. In this post, we attempt to demystify this strange occurrence and give you some tools to help when it happens to you. In ASP.NET Core side, received the PDF stream and saved the converted PDF file.Sometimes you might experience an unexpected, and occasionally dramatic size increase when saving your PowerPoint presentation as a PDF on Mac.In ASP.NET Web API (service), the stream (input document) is converted into PDF in the service side and returned the response with resultant PDF.In ASP.NET Core sample, load the existing presentation document using Essential Presentation and send that document as stream to Web API (service) application.In this sample, the following things have been done: Return File(outputStream, "application/pdf", "Sample.pdf") OutputStream = new MemoryStream(await ()) Gets PDF from content stream if service got success Dispose the input stream and client instances Response = await client.PostAsync(requestUri, new StreamContent(inputStream)) Posts input presentation document to service and gets resultant PDF as content of HttpResponseMessage #region Service approach to send presentation document as stream and gets resultant converted PDF from it.

Container can store the video data and audio streams, subtitles, video metadata, codec and more. Video container – file systems designed to interface between the OS (operating system) and the video data. Media codec – computer program used for compressing and then decompressing a video file. For videos, it measures in pixels, here are the most popular horizontal ones: 426 x 240 (240p), 640 x 360 (360p), 854 x 480 (480p), 1280 x 720 (720p), 1920 x 1080 (1080p), 2560 x 1440 (1440p) and 3840 x 2160 (2160p).Īspect ratio – The aspect ratio of an image describes the proportional relationship between its width and its height. Video dimensions – Width and height of the video. Master version – uncompressed version of your final video, usually weighs a lot.įrame rate / FPS – Number of frames per second. Here’s a helpful vocabulary that will help you learn your way around the world of video compression. In this article, you will find the basic vocabulary as well as everything else you need to know about video compression, video compressors, and 4 free tools to compress your videos for any goal you have. Moreover, compressing videos can require some extra knowledge about video formats (if you don’t use, which is optimized for people without any video editing experience). If you’re new to video editing, many of the existing parameters of video can be very confusing.
