答复: How to enable OpenVG in Webkit
Hello Pawan,
Thanks for your reply.
I’ve ever found this web
page through Google search, and it indicates that OpenVG in Webkit source
is not available. So it
seems that we can’t enable OpenVG directly by implementing OpenVG as a special
paint engine like the way in
Webkit source.
I am just wondering
whether it is possible to enable OpenVG indirectly by treating OpenVG as a graphic
backend of already supported
paint engine in Webkit, such as treating OpenVG as a backend of Cairo
which is paint engine of GTK
port or as a backend of QPainter which is paint engine of Qt port.
Do you have some experience
about this topic? And can give me some advice about the feasibility of this
approach?
Thanks a lot.
Best regards.

Hello
Chen,
OpenVG
in Webkit source is incomplete.
I
had tried this in December 2011 but in vain.

Hello
everyone,
I'd like to ask some questions about how to enable OpenVG in Webkit, and my
working version of Webkit is "WebKit-r87722".
I have noticed that there are some source codes in
"WebCore/platform/graphics/openvg" directory,so it seems that Webkit
has some internal support for OpenVG, but right now I don't know how to utilize
these code.
So my question is:
1) Does the above mentioned code really work ? Is it possible to enable OpenVG
in Webkit?
2) Does anybody know how to enable OpenVG in Webkit? Could you provide some
instructions about how to compile the source or provide a build script.
Thanks in advance.
Best regards
