--- --- # File Viewer The File Viewer has been created using the [ViewerComponent](https://alfresco.github.io/adf-component-catalog/components/ViewerComponent.html) from the ADF. The Viewer has four main areas:  1. [Header & Toolbar](#header-and-toolbar) 2. [Content](#content) 3. [Thumbnails side pane](#thumbnails-side-pane) 4. [Viewer Controls](#viewer-controls) ## Header and Toolbar The Header & Toolbar section of the viewer contains a number of features that relate to the file currently being displayed: - Close 'X' will return the user to the folder that contains the file. - The name and file type icon is shown in the middle. - Next and previous buttons will be displayed either side of the file name so that users can navigate to other files in the folder without navigating away from the viewer. - Finally, on the right hand side an actions toolbar provides users with the ability to download, favorite, move, copy, delete, manage versions and view info panel. ## Content The File Viewer consists of four separate views that handle displaying the content based on four types of content, covering various [file/mime](https://alfresco.github.io/adf-component-catalog/components/ViewerComponent.html#supported-file-formats) types: - Document View: PDF files are displayed in the application File Viewer, for other document types (DOCX etc) then a PDF rendition is automatically retrieved. - Image View: JPEG, PNG, GIF, BMP and SVG images are natively displayed in the application File Viewer. - Media View: MP4, MP3, WAV, OGG and WEBM files are played natively application File Viewer. The File Viewer will download, by default, 50MB of the content at a time to ensure a smooth playback of the content. - Text View: TXT, XML, JS, HTML, JSON and TS files are natively displayed as text in the application File Viewer. ## Thumbnails side pane The Document View includes a thumbnails pane which can be activated by a button in the Viewer Actions toolbar. Clicking on a thumbnail will take a user directly to the selected page and as users scroll through a document the current page is highlighted in the pane. ## Viewer Controls At the bottom of the content the Viewer Controls allow users to interact with the content in various ways; the actions available are dependant on the type of content being displayed. - Document View: - Activate/Deactivate thumbnails pane - Previous/Next page - Jump to page number - Zoom in/out - Fit to page - Print - Image View: - Zoom in/out - Rotate left/right (does not alter content in the repository) - Reset image - Print - Media View: - Play/pause - Timeline position - Toggle audio - Audio volume - Full screen
