摘要： A method and an apparatus for determining an up scale factor and a down scale factor according to a scale factor received from a graphics application program interface (API) to scale a graphics data in a graphics processing unit (GPU) are described. The up scale factor and the down scale factor may be precisely stored in the GPU based on a fixed number of bits. An actual scale factor which can be precisely stored in the GPU corresponding to the scale factor may differ from the scale factor with a difference. Graphics commands may be sent to the GPU to scale the graphics data according to the up scale factor and the down scale factor separately. A combined scale factor corresponding to a combination of the up scale factor and the down scale factor may differ from the scale factor less then the difference between the actual scale factor and the scale factor.
摘要翻译： 描述了一种用于根据从图形应用程序接口（API）接收的缩放因子来确定上比例因子和缩小比例因子以在图形处理单元（GPU）中缩放图形数据的方法和装置。 可以基于固定数量的比特将上比例因子和缩小比例因子精确地存储在GPU中。 可以精确地存储在对应于比例因子的GPU中的实际比例因子可能与具有差异的比例因子不同。 可以将图形命令发送到GPU，以分别根据上比例因子和缩小比例因子缩放图形数据。 对应于上调比例因子和下调比例因子的组合的组合比例因子可能与小于实际比例因子和比例因子之间的差异的比例因子不同。
