通过Office自带的类库word文档中插入图片，图片大小的单位为磅

而文档中，图片的大小已经固定，为CM。

实际工作中，首先将图片插入到word中，根据目前的大小，计算转换为目标大小的比率，将长宽按照目标大小进行缩放即可。

msword.InlineShape spa = oOperateDoc.Tables[oOperateDoc.Tables.Count].Cell(1, 1).Range.InlineShapes.AddPicture(jietuA);float yuanwidth = spa.Width;float yuanheidht = spa.Height;double bilv = GetChangepicSizeRation(yuanwidth,yuanheidht, targetW, targetH);spa.Width = (float)(yuanwidth * bilv);spa.Height = (float)(yuanheidht * bilv);

　　

 

private double GetChangepicSizeRation(double width_pt, double height_pt, double targetWidthCM, double targetHeightCM)        {            //CM转pt            double p = 0.03527;// 0.03759;  //1pt=0.3759mm            double TargetWdithPt = targetWidthCM / p;            double TargetHeightPt = targetHeightCM / p;            double[] bilv = new double[2];            bilv[0] = TargetWdithPt / width_pt;            bilv[1] = TargetHeightPt / height_pt;            return (bilv[0] > bilv[1] ? bilv[1] : bilv[0]);        }
