示例1: copyToPlatformTexture
bool ImageBuffer::copyToPlatformTexture(GraphicsContext3D& context, Platform3DObject texture, GC3Denum internalFormat, GC3Denum destType, GC3Dint level, bool premultiplyAlpha, bool flipY)
{
if (!m_layerBridge || !platformLayer() || !isValid())
return false;
Platform3DObject sourceTexture = m_layerBridge->backBufferTexture();
if (!context.makeContextCurrent())
return false;
Extensions3D* extensions = context.extensions();
if (!extensions->supports("GL_CHROMIUM_copy_texture") || !extensions->supports("GL_CHROMIUM_flipy")
|| !extensions->canUseCopyTextureCHROMIUM(internalFormat, destType, level))
return false;
// The canvas is stored in a premultiplied format, so unpremultiply if necessary.
context.pixelStorei(Extensions3D::UNPACK_UNPREMULTIPLY_ALPHA_CHROMIUM, !premultiplyAlpha);
// The canvas is stored in an inverted position, so the flip semantics are reversed.
context.pixelStorei(Extensions3D::UNPACK_FLIP_Y_CHROMIUM, !flipY);
extensions->copyTextureCHROMIUM(GraphicsContext3D::TEXTURE_2D, sourceTexture, texture, level, internalFormat, destType);
context.pixelStorei(Extensions3D::UNPACK_FLIP_Y_CHROMIUM, false);
context.pixelStorei(Extensions3D::UNPACK_UNPREMULTIPLY_ALPHA_CHROMIUM, false);
context.flush();
return true;
