This extended bitmap is returned back to the calling method. It would be redundant to mention that TLV renderer class +doesnot interface with Openvg or EGL in any form. + +Software Renderer class - Traditional software renderer which interfaces with Openvg and renders content using software renderer.Makes use of +VG and VGI calls for its job. + +Harware Renderer Class - Hardware renderer which makes use of hardware openvg APIs in combination with EGL APIs.The context information is created +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 +EGL_SUCCESS even if an egl function returns FALSE. + +EGL and Openvg have to be compiled before compiling VGRenderer +VGRenderer has to be compiled before compiling SVGEngine or AknIcon.
