For the limit of the effect of the automatic feature extraction which is in low reliability,accuracy and velocity,the automatic currency check of raster graphic data can not satisfy the requirement of production and operation.So,this article uses the change ratio of the pixel number to realize the automatic currency check of raster graphic data.The experiment shows this method is feasible.
