寻找插入向XPS文件中插入图片的实现方式良久，才找到正确的方法。废话不多说直接上代码。。。
//插入事件
private void button1_Click(object sender, EventArgs e)
{
string originalDocument = "";//读取模板
string detinationDocument =AppDomain.CurrentDomain.BaseDirectory+"newXps.xps";//生成的新文件
openFileDialog1.Filter = "图片文件(*.xps)|*.xps";
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
try
{
originalDocument = openFileDialog1.FileName;
int png_x = Convert.ToInt32(txtX.Text.Trim());
int png_y = Convert.ToInt32(txtY.Text.Trim());
if (File.Exists(detinationDocument))
File.Delete(detinationDocument);
using (Package package = Package.Open(originalDocument, FileMode.Open, FileAccess.Read))
{
using (Package packageDest = Package.Open(detinationDocument))
{
string inMemoryPackageName = "memorystream://miXps.xps";
Uri packageUri = new Uri(inMemoryPackageName);
PackageStore.RemovePackage(packageUri);
PackageStore.AddPackage(packageUri, package);
XpsDocument xpsDocument = new XpsDocument(package, CompressionOption.Maximum, inMemoryPackageName);
XpsDocument xpsDocumentDest = new XpsDocument(packageDest, CompressionOption.Normal, detinationDocument);
var fixedDocumentSequence = xpsDocument.GetFixedDocumentSequence();
DocumentReference docReference = xpsDocument.GetFixedDocumentSequence().References.First();
FixedDocument doc = docReference.GetDocument(false);
PageContent content = doc.Pages[0];
FixedPage fixedPage = content.GetPageRoot(false);
//大容器
Canvas containCanvas = new Canvas();
containCanvas.Width = fixedPage.Width;

//xps缩放比例
double RenderTrans = 1;
//获得页面宽度和高度

//循环xps字元素，查找指定内容

{
UIElement DocFpUiElem = fixedPage.Children[i];
if (DocFpUiElem is Glyphs)
{

//找到位置

//Y坐标*缩放比例-图像本身高度
Canvas.SetTop(cvs, Convert.ToDouble(png_y));
img.Width = Convert.ToDouble(62);
img.Height = Convert.ToDouble(27);
//填入图片
cvs.Children.Add(img);
//将图片cvs 添加到大容器中
containCanvas.Children.Add(cvs);
//将大容器填充到 xps Page页面当中
fixedPage.Children.Add(containCanvas);
((IAddChild)content).AddChild(fixedPage);
//创建写入流，输出保存文件
var writter = XpsDocument.CreateXpsDocumentWriter(xpsDocumentDest);
writter.Write(fixedPage);
//释放
xpsDocumentDest.Close();
xpsDocument.Close();
