but if I explicitly cast the values to size_t, the error goes away. prettyprint 複製 size_t firstNonZero[2] = { static_cast<size_t>(-1), static_cast<size_t>(-1) }; Why is a narrowing conversion required? In other words, why is -1 not coercible to size_t without any...

DIB的颜色信息储存在自己的颜色表中,程序一般要根据颜色表为DIB创建逻辑调色板。在输出一幅DIB之前,程序应该将其逻辑调色板选入到相关的设备上下文中并实现到系统调色板中,然后再调用相关的GDI函数(如::SetDIBitsToDevice或::StretchDIBits)输出DIB。在输出过程中,GDI函数会把DIB转换成DDB,这项工作主要包括以下两步: ...
