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.

SalGraphics::mirror() question
Hi all, Some time ago, all the SalGraphics::mirror() functions added a check to get the width from OutputDevice::GetOutWidthPixel() if the class is VirtualDevice. My questions are: 1. Why is this necessary? 2. What is the difference between SalGraphics::GetGraphicsWidth() and OutputDevice::GetOutWidthPixel()? Any insights here would be really helpful!
