    • A method for generating a raster image according to a tile drawing command includes acquiring a tile drawing command for repeatedly rasterizing a specified object, determining whether an interval in which the object is repeated in a predetermined direction based on the acquired tile drawing command is an integer pixel width in a coordinate system of the raster image, generating, based on the acquired tile drawing command, another tile drawing command for repeatedly rasterizing the object in the predetermined direction in an interval of an integer pixel width in the coordinate system, wherein the generated another tile drawing command includes a plurality of pieces of information corresponding to a plurality of scaling factors, scaling, based on the another tile drawing command, the object to repeatedly rasterize the object in the predetermined direction.
    • 根据瓦片绘制命令生成光栅图像的方法包括获取用于重复光栅化指定对象的瓦片绘制命令,基于所获取的瓦片绘图命令确定在预定方向上重复对象的间隔是否为整数 在所述光栅图像的坐标系中的像素宽度,基于所获取的平铺绘制命令,生成用于在所述坐标系中以整数像素宽度的间隔在所述预定方向上重复光栅化所述对象的另一块绘图命令,其中, 另一个瓦片绘制命令包括与多个缩放因子相对应的多条信息,基于另一个瓦片绘制命令缩放该对象以在预定方向上重复地光栅化对象。
