1 VGRenderer is the interface class which interfaces with the underlying 3 renderer classes - TLV , Software and Hardware renderers. |
|
2 |
|
3 TLV Renderer Class - This class captures the openvg command sequence into a encoded form of TLV(Type-Length-Value)command buffer and fills |
|
4 into an Extended CFbsBitmap. This extended bitmap is returned back to the calling method. It would be redundant to mention that TLV renderer class |
|
5 doesnot interface with Openvg or EGL in any form. |
|
6 |
|
7 Software Renderer class - Traditional software renderer which interfaces with Openvg and renders content using software renderer.Makes use of |
|
8 VG and VGI calls for its job. |
|
9 |
|
10 Harware Renderer Class - Hardware renderer which makes use of hardware openvg APIs in combination with EGL APIs.The context information is created |
|
11 and maintained by egl in this case.Please look out for the TRUE return value of any egl function(eglcreate..eglget) as eglGetError might return an |
|
12 EGL_SUCCESS even if an egl function returns FALSE. |
|

14 EGL and Openvg have to be compiled before compiling VGRenderer |

15 VGRenderer has to be compiled before compiling SVGEngine or AknIcon. |
