ArcEngine地图图片输出

注：outPicture -- Button按钮

    savFileDialog1 -- 保存对话框控件

 

自带例子位置：

在ArcGIS安装路径下的Developerkit\SamplesNET\Engine\ExportActiveView\VBNet

自带的例子比下面的还好

 

//地图图片输出
        private void outPicture_Click(object sender, EventArgs e)
        {
            saveFileDialog1.Filter = "JPEG(*.jpg)|*.jpg|BMP(*.BMP)|*.bmp|EMF(*.emf)|*.emf|GIF(*.gif)|*.gif|AI(*.ai)|*.ai|PDF(*.pdf)|*.pdf|PNG(*.png)|*.png|EPS(*.eps)|*.eps|SVG(*.svg)|*.svg|TIFF(*.tif)|*.tif";
            saveFileDialog1.Title = "输出地图";
            saveFileDialog1.RestoreDirectory = true;
            saveFileDialog1.FilterIndex = 1;
            saveFileDialog1.ShowDialog();
        }
