METHOD AND APPARATUS FOR IMPLEMENTING VECTOR FONT

摘要

A method and an apparatus for implementing a vector font are provided, which are used to solve the problem of excessively large computation expenses in drawing the vector font in prior art. The method comprises: a bitmap region with the equal size as a display region of a reference font is established (S10), and after filling the bitmap region with the complementary color of the reference font color, the reference font is drawed in the bitmap region (S11); an Alpha table with the equal size as the bitmap region is constructed, and the transparency of each pixel point in the bitmap region is recorded in the Alpha table (S12); the Alpha table is zoomed according to a ratio between the size of a destination vector font and the size of the reference font; the destination vector font is drawed in a destination bitmap region according to the transparency of each pixel point in the zoomed Alpha table (S15). The apparatus comprises: a reference font drawing module, an Alpha table constructing module, an Alpha table zooming module and a destination vector font drawing module. Applying the method and the apparatus, storage cost and time cost in drawing the vector font is decreased significantly.
