示例1: EnumerateSceneTextures

uint32 TextureHelper::EnumerateSceneTextures(DAVA::Scene* scene)
{
	Map<String, Texture *> textureMap;
	EnumerateTextures(scene, textureMap);

	uint32 sceneTextureMemory = 0;
	for(Map<String, Texture *>::const_iterator it = textureMap.begin(); it != textureMap.end(); ++it)
	{
		Texture *t = it->second;
		//We need real info about textures size. In Editor on desktop pvr textures are decompressed to RGBA8888, so they have not real size.
        TextureDescriptor *descriptor = TextureDescriptor::CreateFromFile(t->GetPathname());
        if(descriptor)
        {
            FilePath imageFileName = GPUFamilyDescriptor::CreatePathnameForGPU(descriptor, (eGPUFamily)descriptor->exportedAsGpuFamily);
            if(imageFileName.IsEqualToExtension(".pvr"))
            {
                sceneTextureMemory += LibPVRHelper::GetDataSize(imageFileName);
