OpenVG is an application programming interface (API) for hardware-accelerated two-dimensional vector and raster graphics. It has not apparently proven immensely popular, but I will need it for drawing text overlays on video images in a later chapter. This is a minimal chapter on OpenVG.
You can build the programs in this chapter using the following Makefile:
DMX_INC = -I/opt/vc/include/ -I /opt/vc/include/interface/vmcs_host/ -I/opt/vc/include/interface/vcos/pthreads -I/opt/vc/include/interface/vmcs_host/linux
INCLUDES = $(DMX_INC) ...
