C#+ArcEngine打印横向和纵向调整
在用C#开发ArcEngine程序实现Pagelaylout打印功能的时候,在实现横向打印的时候,总会出现如下图的情况
通过修改axPageLayoutControl1.Page.Orientation = 1;属性发现也不作用;需要通过修改IMapFrame进行修改能够实现横向和纵向的合理变化;
横向显示代码如下
IMap pMap;
IGraphicsContainer pGraphicsContainer;
IMapFrame pMapFrame;
pMap = axPageLayoutControl1.ActiveView.FocusMap;
pGraphicsContainer = (IGraphicsContainer)axPageLayoutControl1.PageLayout;
pMapFrame = (IMapFrame)pGraphicsContainer.FindFrame(pMap);
ISymbolBorder pSymborder = new SymbolBorderClass();
pSymborder.CornerRounding = 0;
IBorder pBorder = pSymborder;
pMapFrame.Border = pBorder;
pMapFrame.ExtentType = esriExtentTypeEnum.esriExtentBounds;
IElement pElement = (IElement)pMapFrame;
IEnvelope pEnvelop = new EnvelopeClass();
pEnvelop.PutCoords(0.5, 0.5, 29.2, 20.5); //这里设置mapframe的大小
IGeometry pGeometry = pEnvelop;
pElement.Geometry = pGeometry;
IPage pPage = axPageLayoutControl1.Page;
pPage.Orientation = 1;
pPage.PutCustomSize(29.7, 21.0); //这里设置page的大小
axPageLayoutControl1.ActiveView.Refresh();
效果如下图
纵向显示代码如下
IMap pMap;
IGraphicsContainer pGraphicsContainer;
IMapFrame pMapFrame;
pMap = axPageLayoutControl1.ActiveView.FocusMap;
pGraphicsContainer = (IGraphicsContainer)axPageLayoutControl1.PageLayout;
pMapFrame = (IMapFrame)pGraphicsContainer.FindFrame(pMap);
ISymbolBorder pSymborder = new SymbolBorderClass();
pSymborder.CornerRounding = 0;
IBorder pBorder = pSymborder;
pMapFrame.Border = pBorder;
pMapFrame.ExtentType = esriExtentTypeEnum.esriExtentBounds;
IElement pElement = (IElement)pMapFrame;
IEnvelope pEnvelop = new EnvelopeClass();
pEnvelop.PutCoords(0.5, 0.5, 20.5,29.2); //这里设置mapframe的大小
IGeometry pGeometry = pEnvelop;
pElement.Geometry = pGeometry;
IPage pPage = axPageLayoutControl1.Page;
pPage.Orientation = 2;
pPage.PutCustomSize(21.0, 29.7); //这里设置page的大小
axPageLayoutControl1.ActiveView.Refresh();
效果如下图
本实例使用A4纸张的尺寸进行测试,具体的应用还要根据实际的情况进行设置。
