C# 클래스 SIL.FieldWorks.SharpViews.LayoutTransform

A LayoutTransform contains the information that a Box needs to transform points in its own coordinate system (or possibly its container's coordinate system) into points relative to the view as a whole. This class is immutable; if you need a different one, make a new one.

LayoutTransform ( int dx, int dy, int dpiX, int dpiY ) : System	This constructor makes a transform suitable for a box whose top left is dx below and dy to the right of the top left of the whole view area, and which will be laid out as if for a device resolution of dpiX pixels per inch horizontally and dpiY vertically.
MpToBorderPixelsX ( int mp ) : int	Convert a border width in mp to pixels. Should not answer zero unless mp is zero.
MpToBorderPixelsY ( int mp ) : int	Convert a border height in mp to pixels. Should not answer zero unless mp is zero.
MpToPixelsX ( int mp ) : int	Transform a distance in millipoints (72,000 per inch) into pixels in the X direction.
MpToPixelsY ( int mp ) : int	Transform a distance in millipoints (72,000 per inch) into pixels in the X direction.
OffsetBy ( int dx, int dy ) : LayoutTransform	Answer a layout transform suitable for a child box whose left and top are dx and dy. (Keep InitializeOnlyOffsetBy consistent with this.)
ToRoot ( Point p ) : Point	Converts a Point in box coordinates to whole-view coordinates.

InitializeOnlyOffsetBy ( int dx, int dy ) : void	This method is internal only because I definitely don't want it as public as 'protected'. It should ONLY be used by subclass methods constructing copies offset by the specified amount.
MulDiv ( int mp, int dpi, int div ) : int	Multiply the first two arguments and divide by the third. Assume the result will not overflow, but the intermediate product may be larger than an int. Round to the closest integer result. Assumes div is not zero.
MulDivNotToZero ( int mp, int dpi, int div ) : int	Multiply the first two arguments and divide by the third. Assume the result will not overflow, but the intermediate product may be larger than an int. Round to the closest integer result, except that the result must not be zero unless the first argument is zero.
