Adobe AIR

Adobe AIR is a cross-operating system runtime that allows Web application developers to use their existing Web development skills (HTML, Javascript, Adobe Flash, Adobe Flex, Ajax) to build and deploy rich Internet applications on the desktop.

New

• Moving to WKWebView for StageWebView on iOS - Starting AIR 26, For StageWebView on iOS, we now use WKWebView (instead of UIWebView) behind the scene, which uses the WebKit engine to render WebViews. For more information on WKWebView, see https://developer.apple.com/reference/webkit/wkwebview. This change does not impact ActionScript developers directly. However, because of a few known WebKit bugs, there may be some workflow changes in existing iOS Apps
• D2D Vector Printing Support - This feature brings back vector printing in Microsoft Edge in Windows 10 and Immersive IE in Windows 8 in "Out of Process" mode. This feature will not only enhance the speed of printing but also reduce the data size input. Initially, a mixed way to print (GDI Vector + D2D Bitmap) has been used in ActiveX Windows 8.1 and above. Now Vector printing will be done through D2D APIs in Windows 8.1 and Windows 10. There is no difference in the Actionscript API’s.
• DeviceRotation Event Handler for Mobile AIR - When a device is rotated, the orientation of the plane defining device screen changes. This change can be depicted in terms of a Rotation Vector, which can be represented by Roll-Pitch-Yaw or Quaternions data. The DeviceRotation event handler is used to fetch this data. One scenario where this data can be useful is to update the viewport of spherical videos when the device is rotated. This event handler has been introduced in AIR 26, where we have added a new DeviceRotation class which dispatches DeviceRotationEvent based on the activity detected by the device's
• motion sensors namely Accelerometer and Gyroscope.
• Enhanced Profile -With AIR 26, we are introducing a new stage3D profile "Enhanced" for AIR Mobile. This will be a new constant in Context3DProfile class. Availability of "enhanced" profile indicates the availability of AGAL4. The same profile name can be used in requestContext3D and requestContext3DMatchingProfiles methods of Stage3D. AGAL 4 introduces a new opcode "tld" and new Vertex Sampler register "vs" for fetching texture in a vertex shader. 'tld' is similar to 'tex' opcode used in the fragment shader. But unlike 'tex' opcode, 'tld' requires a level of detail ( LOD ) value for parameter since GPU does not support the automatic calculation of LOD in the vertex shader.
• Vertex Texture Fetch - With the introduction of new Stage3D profile i.e. 'ENHANCED', Vertex Texture Fetch is now available in AIR mobile. Texture Data will be available in Vertex Shader using AGAL4 and Enhanced profile. AGAL 4 introduces a new opcode "tld" and new Vertex Sampler register "vs" for fetching texture in the vertex shader. 'tld' is similar to 'tex' opcode used in the fragment shader. But unlike 'tex' opcode, 'tld' requires a level of detail ( LOD ) value as a parameter since GPU does not support the automatic calculation of LOD in the vertex shader.
