如何创建多页面注释编辑工具
本帖最后由 Richard.Ma 于 2017-5-24 16:10 编辑附件是在VS2017中编写的.NET4C＃演示程序，演示了如何使用ImageViewer Control以及Annotations SDK来浏览多页输入文档，向文档添加编辑对象，然后将文档平铺并保存为 300x300 8.5inx11in，无论输入的大小是多少。

以下是每个部分的相关代码：
为图像查看器中包含的每个页面添加一个容器：
//Add an Annotation Container for each page to the Container Collection
pageContainers.Clear();
for (int page = 1; page <= imageViewer.Image.PageCount; page++)
{
AnnContainer pageContainer = new AnnContainer();
pageContainer.Mapper.MapResolutions(imageViewer.Image.XResolution,
imageViewer.Image.YResolution,
imageViewer.Image.XResolution,
imageViewer.Image.YResolution);
pageContainer.Size = pageContainer.Mapper.SizeToContainerCoordinates(imageViewer.ImageSize.ToLeadSizeD());
pageContainers.Add(pageContainer);
}
//Attach the first container to the annAutomation
annAutomation.AttachContainer(pageContainers.FirstOrDefault(c => pageContainers.IndexOf(c) + 1 == imageViewer.Image.Page), null);
调整大小并保存：
//Burn each container to each page and then resize it to 300x300 DPI 8.5inx11in
RasterImage flatImage = null;
for (int page = 0; page < imageViewer.Image.PageCount; page++)
{
imageViewer.Image.Page = page + 1;
AnnWinFormsRenderingEngine renderer = annManager.RenderingEngine as AnnWinFormsRenderingEngine;
RasterImage flatPage = renderer.RenderOnImage(pageContainers, imageViewer.Image.Clone());
flatPage.XResolution = 300;
flatPage.YResolution = 300;
SizeCommand size = new SizeCommand()
{
Flags = RasterSizeFlags.Bicubic,
Height = 3300,
Width = 2550
};
size.Run(flatPage);
if (flatImage == null)
flatImage = flatPage;
else
flatImage.AddPage(flatPage);
}
//Save the final FlatImage to disk
using (RasterCodecs codecs = new RasterCodecs())
codecs.Save(flatImage, dlg.FileName, RasterImageFormat.RasPdfG4, 1);
//Reset the page back to the first page
imageViewer.Image.Page = 1;
