![]() That opens the project folder in File Explorer. Right-click the project node, and click Open Folder in File Explorer. If you see only an option to Add a new folder, then (with the project node selected) make sure that Show All Files is toggled off. Add a new filter as a child of the Assets filter name the new filter "Samples". Go to Solution Explorer in Visual Studio. Paste (into the Assets folder) the Samples folder that you just copied. That opens the Assets folder in File Explorer. Right-click the Assets folder (it's a child of the project node), and click Open Folder in File Explorer. In File Explorer, select that Samples folder, and copy it to the clipboard. ![]() If you want to see those files in the repo online, then you can visit WindowsAppSDK-Samples/Samples/PhotoEditor/cs-winui/Assets/Samples/. Having done that, you'll find the asset files that we'll be using in the folder \WindowsAppSDK-Samples\Samples\PhotoEditor\cs-winui\Assets\Samples (use this folder for both a C# and a C /WinRT project). zip) the Windows App SDK samples repo (see WindowsAppSDK-Samples). But first you'll need to obtain a copy of the files. In this section you'll add those assets to your project. ![]() The app that we'll be building carries image files around with it in the form of asset files and those are the photos that it displays. You can target the most recent release (not preview) of the client operating system. Name the project SimplePhotos, and (so that your folder structure will match the one described in this tutorial) uncheck Place solution and project in the same directory. In Visual Studio, create your choice of a new C# or C project from the Blank App, Packaged (WinUI 3 in Desktop) project template. Be sure to check any limitations and known issues in those release notes, since those might affect the results of following along with this tutorial and/or running the app we'll build. There are release notes for each channel. For example: USYS2BFC65091708FC20F656E8CC6178FB09_idsesprod01.a.'ll find release notes topics along with the Windows App SDK release channels topic. The ID of the OAuth 2 access token used for identification and authorization of the user (and agent) making the request. The Y coordinate for positioning the tile in a Deep Zoom image viewer. The X coordinate for positioning the tile in a Deep Zoom image viewer. For more information on levels, go to Deep Zoom Overview. Each level is the size 2(level)x2(level). Levels are counted from the 1x1 pixel as level 0. To obtain the DZI document for each PAL, use this template. You will then need to get the image parameters from the DZI Document. With this information, a Deep Zoom client is able to build a request for tiling. The DZI document describes the format, level, width, height and overlap attribute of an image. You should have a PAL URI from the record data that represents an image resource. For information on getting an access token, see the Authentication and Access Tokens guide. This can be an unauthenticated access token. Higher numbers correspond to a higher resolution level. Each image in the subfolder directory is labeled with its level of resolution. Deep Zoom ImagesĪ Deep Zoom Image (DZI) has two parts: a DZI file and a subdirectory of image files. Subsequent regions are downloaded as the user pans to or zooms into them. This reduces the time required for initial load by downloading only the region being viewed and/or only at the resolution at which it is being displayed. Images are broken into tiles and then displayed as required. Note This information is only intended for partnering organizations who have entered into record sharing agreements with FamilySearch.ĭeep Zoom allows users to zoom in on a large, high-resolution image or a collection of images.
