C# 클래스 SIL.FieldWorks.SharpViews.PaintTransform

A PaintTransform is used when actually painting boxes, or performing similar opertions like hit testing that depend on actual drawing coordinates. The first four constructor arguments are the same as for the base class, and should be the same as the most recent layout operation performed on the box to which the transform is passed. See LayoutTransform for doc. The next four arguments give the resolution at which drawing is actually done, and, in paint pixels, another offset. Typically this offset represents the amount by which the view is scrolled. Conceptually they are the distance that the top left of the view is above and left of the top left of the area in which it is drawn. This means that, after a position relative to the top left of the view is computed as the place to draw something, to convert to paint coordinates we multiply by the ratio of dpiXPaint/dpiXLayout, then subtract dxScroll...and similarly for Y.

PaintTransform ( int dxLayout, int dyLayout, int dpiXLayout, int dpiYLayout, int dxScroll, int dyScroll, int dpiXPaint, int dpiYPaint ) : System
PaintTransformOffsetBy ( int dx, int dy ) : PaintTransform	Answer a layout transform (actually a PaintTransform) suitable for a child box whose left and top are dx and dy.
ToLayout ( Point paintPoint ) : Point	Convert a point in paint coordinates to one relative to the box that uses this transformation.
ToLayoutX ( int x ) : int	Convert an X coordinate from paint to layout coords.
ToPaint ( Point layout ) : Point	Convert a complete point to Painting coordinates (not yet tested)
ToPaint ( Rectangle rLayout ) : Rectangle	Convert a rectangle relative to the box for which this transform is configured to one in paint coordinates. Todo: tests and implementation of differing DPI and non-zero ScrollOffset.
ToPaintX ( int xs ) : int	Convert a position relative to the box for which this is the transform to one in paint coordinates. Todo: tests and implementation of differing DPI and non-zero ScrollOffset.

ConvertToPaint ( Point source, Rect srcRect, Rect dstRect ) : Point	Currently not used: given a point in destination coordinates and two rectangles such as are returned by SourceRect and DestRect, generate the point (ToPaintX(source.X), ToPaintY(source.Y)) that would be returned by a transformation represented by that transformation. (not yet used or tested)
ConvertToPaint ( Rect source, Rect srcRect, Rect dstRect ) : Rect	Currently only used in testing: given a point in destination coordinates and two rectangles such as are returned by SourceRect and DestRect, generate the point (ToPaintX(source.X), ToPaintY(source.Y)) that would be returned by a transformation represented by that transformation. (not yet used or tested)
FromSourceAndDest ( Rect srcRect, Rect dstRect ) : PaintTransform	Return the PaintTransform that would produce the indicated Source and Dest Rects.
ToPaint ( Rect rLayout ) : Rect	Convert a rect relative to the box for which this transform is configured to one in paint coordinates. Todo: tests and implementation of differing DPI and non-zero ScrollOffset. Currently only used in making test data.
