The Haiku port also uses no OpenGL. I have versions of CoordinatedGraphics and TextureMapper extracted from old verisons of WebKit which I maintain with the port (TextureMapperImageBuffer is the entry point for that): https://github.com/haiku/webkit/blob/rebased/Source/WebCore/platform/graphics/texmap/TextureMapperImageBuffer.cpp The commit which restores this may serve as a reference (but may not apply directly to current sources): https://github.com/haiku/webkit/commit/966df671f60cc716233952c5e80c5fd52d6ce785 -- Adrien Destugues / PulkoMandy http://pulkomandy.tk ___ webkit-dev mailing list webkit-dev@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-dev

Indeed... we did such port for a customer based on WebKit-EFL (now out-of-tree) and it worked, but was a major pain to get there due CoordinatedGraphics and TextureMapper being heavy on GL calls... however in our case it was software rendering only, no GL at all. -- Gustavo Sverzut Barbieri http://profusion.mobi embedded systems -- MSN, GTalk, FaceTime: barbi...@gmail.com Skype: gsbarbieri Mobile: +55 (16) 99354-9890 ___ webkit-dev mailing list webkit-dev@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-dev

Thanks and Regards, Nagendra Hi Nagendra, You are not going to get WebKit working with OpenGLES 1.1 unless you have an experienced engineer making large modifications to the source code. Instead, you should just turn off OpenGL/OpenGLES support. Just build with -DENABLE_OPENGL=OFF. It is optional, you just lose hardware acceleration. You should hopefully have no trouble with this. If you have a requirement to use OpenGLES regardless, then you may need to reevaluate the feasibility of your project.

Re: [webkit-dev] WebKit opengl
Hi Dean, Thanks for the reply. I actually have a embedded device with opengl es 1.1 and WebKit which is 7 years old, now requirement is to update the WebKit using the same opengles1.1 i.e. no option to update opengles1.1. So as you said we need opengles2 or opengl4 to upgrade WebKit as WebKit has dependencies with opengl for some features. Is this correct? Do I any other option to do this.

I don't understand what you are asking, sorry. It's possible to make a port of WebKit that doesn't rely on OpenGL. I think the Windows port is one example. Technically Apple's iOS/macOS ports only directly require OpenGL for WebGL support. Dean ___ webkit-dev mailing list webkit-dev@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-dev

[webkit-dev] WebKit opengl
Hi All, Current build of WebKit using opengl and with custom port, all apps will directly use the opengl calls to draw, making the opengl independent of WebKit. So if I upgrade the WebKit, will the latest WebKit require opengl for any of the new features or can we use opengl delinking WebKit. Thanks and Regards, Nagendra ___ webkit-dev mailing list webkit-dev@lists.webkit.org https://lists.webkit.org/mailman/listinfo/webkit-dev
[webkit-dev] WebKit opengl
Hi All, I am upgrading WebKit for an embedded platform. On the current platform opengl1.1 is being used for rendering, so when I upgrade the WebKit can I choose the option of using opengl 1.1 or 2.0. Or WebKit code mandates to use any particular version of opengl. I checked in WebKit code and observed all opengl 2.0 calls are under a macro. So if this macro is not used, WebKit still permits opengl 1? I am not using any of the WebKit ports, have a custom port. So request for answers irrespective of the port.
