摘要： A system and method is described for rendering a warped brush stroke using a bitmap brush image, the brush stroke being along a arbitrarily curved guideline. The described system and method generate a piecewise linear approximation to the guideline followed by generating polygons with the aid of the linear segments such that the generated polygons are convex and contiguous linear segments result in contiguous polygons. A mapping is identified between segments of the bitmap brush and the polygons such that the corners or the boundaries of the segments of a segment map to the corners or boundaries of a corresponding polygon. The segment of the bitmap brush is mapped into the corresponding polygon using transformations that do not require visiting a pixel in the rendered warped brush stroke more than once. Examples of such transformations include bilinear transformations and texture mapping in combination with tiling.

摘要： In order to allow for application development without requiring extensive graphical design by software developers or extensive software knowledge by graphical designers, applications are separated into a view and a model. Properties in the view and properties in the model are associated through data binding, for example, via a data binding engine. This association allows views to be defined declaratively. Transformations may be necessary to allow the data binding. The data binding allows the data and functionality in the model to be used via the UI as defined in the view. Automatically generated UI and command binding are also enabled.

摘要： A method for drawing a paint stroke with a bitmap brush having pixels located at locations definable in a Cartesian coordinate system. The paint stroke is created by defining a path of a guide line, the path having an arc-length and the guide line having a thickness, and scaling the bitmap brush as a function of the arc-length of the path and the thickness of the guide line. The bitmap brush is then transformed such that the x-axis of the bitmap brush generally aligns with the path and the y-axis of the bitmap brush generally aligns with an instantaneous normal to the path such that the bitmap brush is warped to the guide line.
