The invention relates to a method for accelerating vector graph display on the basis of bitmap buffering, which comprises: buffering a rendering result of a complicated vector object which is continuously displayed in the process of playing vector animation, taking out a corresponding bitmap buffering object when the displayed object appears for the second time, and directly displaying the object on an appointed position through transformation operations. The method for accelerating comprises a pre-buffering strategy, a buffering choosing strategy, a buffer using strategy, a buffer compressing and preserving strategy and a buffer replacing strategy. The method has the advantages that a large amount of calculation is saved, the time for rendering the vector graphs is saved, the display speed is accelerated, the buffer capacity size and the edge curve threshold of a complicated graph are adjusted to achieve the best effect according to the difference of the memory size or the processing speed of an embedded real type device, the operation is simple, only an ID number, the length, the width, the bitmap data, the priority and a frame number which is used recently of the vector object are stored, which can be realized through one simple chained list, a step of rendering and the playing flow are transparent, and the playing flow of the vector animation is not affected.
