我有UIImageView *imageView = [UIImageView new];
imageView.image = [UIImage imageNamed:@"test.jpg"];
。其分辨率为2560 *17722*3
当我加载UIImage时，我发现Xcode中的内存从 12M增加到14M 。
ID3D12CommandQueue::ExecuteCommandLists我认为UIImage占用的内存应该是DrawObject DrawObjects[10];
ID3D12CommandQueue* GCommandQueue = ...
void RenderThread1()
{
ID3D12GraphicsCommandList* clForThread1 = ...
for (int i = 0; i < 5; i++)
clForThread1->RecordDraw(DrawObjects[i]);
}
void RenderThread2()
{
ID3D12GraphicsCommandList* clForThread2 = ...
for (int i = 5; i < 10; i++)
clForThread2->RecordDraw(DrawObjects[i]);
}
void ExecuteCommands()
{
ID3D12GraphicsCommandList* cl[2] = { clForThread1, clForThread2 };
GCommandQueue->ExecuteCommandLists(2, cl);
GCommandQueue->Signal(...)
}
个字节
为什么UIImage占用的内存如此之少;
