摘要：Methods and apparatuses to scale components of user interfaces. To scale aview component according to an arbitrary transformation, which may be represented by ascaling factor, a coordinate transformation, or other parameters, at least one
embodiment of the present invention determines a new transformation for the viewcomponent so that, when the new transformation is used, the boundaries of the viewcomponents are aligned with pixel lines (and/or, other conditions are satisfied). In oneaspect of the invention, a method to scale a view component of a Graphical User Interfaceincludes: adjusting first layout parameters (e.g., coordinates of an origin, a width, a height,a coordinate of a boundary, and others), which correspond to a first transformation toscale the view component, to generate second layout parameters for the view
component; and computing a second transformation from the second layout parametersto scale the view component. In one example according to this aspect, the viewcomponent is scaled using the second transformation; and a Current TransformationMatrix (CTM) is set according to the second transformation. According to the secondlayout parameters, the boundaries of the view component are aligned with pixel lines.
