What is the difference between SalGraphics::GetGraphicsWidth() and > OutputDevice::GetOutWidthPixel()? > The SalGraphics is the underlying operating system graphics primitive, so its size might be much bigger than the Window and/or VDev you have at hand. For the OutputDevice, if mnOutOffX/mnOutOffY is non-zero, then GetOutputWidthPixel/GetOutputHeightPixel (I presume you meant those?) will likely be smaller than the size returned by SalGraphics. VCL Windows are 'lightweight', in that they reuse operating system windows, by e.g. adjusting output offsets and clips. For VirtualDevices, you are most probably right, those values will be equivalent. HTH, -- Thorsten
