示例1: resizeTexture
void UiManager::resizeTexture(const QSize &aSize, const Ogre::MaterialPtr &aMaterial, const Ogre::TexturePtr &aTexture)
{
assert(!aMaterial.isNull());
assert(!aTexture.isNull());
// get the smallest power of two dimension that is at least as large as the new UI size
Ogre::uint newTexWidth = nextHigherPowerOfTwo(aSize.width());
Ogre::uint newTexHeight = nextHigherPowerOfTwo(aSize.height());
if (!aTexture.isNull())
{
std::string txtrName = aTexture->getName();
// remove the old texture
aTexture->unload();
aMaterial->getTechnique(0)->getPass(0)->removeAllTextureUnitStates();
Ogre::TextureManager::getSingleton().remove(aTexture->getHandle());
Ogre::TexturePtr newTxtr = Ogre::TextureManager::getSingleton().createManual(
txtrName, "General", Ogre::TEX_TYPE_2D, newTexWidth, newTexHeight, 0, Ogre::PF_A8R8G8B8,
Ogre::TU_DYNAMIC_WRITE_ONLY);
// add the new texture
Ogre::TextureUnitState* txtrUstate = aMaterial->getTechnique(0)->getPass(0)->createTextureUnitState(txtrName);
// adjust it to stay aligned and scaled to the window
Ogre::Real txtrUScale = (Ogre::Real)newTexWidth / aSize.width();
Ogre::Real txtrVScale = (Ogre::Real)newTexHeight / aSize.height();
txtrUstate->setTextureScale(txtrUScale, txtrVScale);
txtrUstate->setTextureScroll((1 / txtrUScale) / 2 - 0.5, (1 / txtrVScale) / 2 - 0.5);
}
