    摘要: This invention relates to an outline font, and more particularly to a progressive renderable outline font and methods for transforming and rendering the same. Its purpose lies in supplying a progressively renderable Font which can be varied according to the quantity of the data composing the font. The Progressively Renderable Font has the function of controlling the display speed and the quality of the font. For example, if the hardware speed is relatively slow and a high quality font is not needed, only a part of the font data will be transmitted and displayed. On the contrary, if the hardware speed is relatively fast and high quality font is needed, gradually increased data will be transmitted and displayed. Therefore, a font can be transmitted and displayed using minimal data without sacrificing quality. On the other hand, in case of the environment, all the data can be transmitted and displayed so that the quality of the font can be fully realized.

    摘要: The present invention relates to an outline font. The purpose lies in supplying a transforming and rendering method in the shape where the important form of the shape, such as the thickness of the stroke, will be maintained from the basic shape, and at the same time the whole size of the shape can be fitted into a given bounding box. The present invention supplies the transformation method of a handwriting font including searching for the medial axis of a given element, obtaining contact points by using maximal inscribed circles with the medial axis and points of the medial axis as a center, and applying the information about the medial axis points and the contact points in case of a transformation of the element in the transformation method of handwriting where a given element can be optionally transformed in sizes in order to achieve the purpose. The present invention enables the transformation of the shape. In resizing the given element from the box surrounding element to the box where the new element is placed, the important form of the shape, such as the thickness of the stroke, is maintained, and at the same time the size of the whole is transformed in accordance with the optionally given box.
