Implementing a solution that views documents stored in a cloud-based system, such as a content management system, engineering drawing repository or a technical publication library, can present some challenges. Each requires consideration to promote a good experience for the end user. There are four common challenges that you could face when implementing a cloud-based document viewing system: working with multiple file formats, variations in document size, browser-compatibility with HTML5, and viewing documents on mobile devices.
Multiple File Formats
First, the documents that you want to view may be in many different formats. They may be PDF, TIFF, Word, Excel, PowerPoint, CAD, or many others. The device that is being used to display the content often may not have the right software needed to display the document or image. This issue is further compounded by the varying number of devices that the content will be viewed on. A common solution is to convert the files on the server to a generic format that can be viewed by many devices, but this presents other issues. For example, most browsers and devices today can display JPEG or PNG formats, but both of these are raster image formats. If a text-based document such as a Word file is converted to an image, the display quality deteriorates when a page is zoomed and you lose interactivity with the content.
