我注意到幻灯片上的一些差异
.rels
,从正确的手动制作的幻灯片:
<?xml version="1.0" encoding="UTF-8" standalone="true"?>
<Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
<Relationship Target="../slideLayouts/slideLayout8.xml" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/slideLayout" Id="rId1"/>
</Relationships>
不正确的一个看起来像:
<?xml version="1.0" encoding="UTF-8"?>
<Relationships xmlns="http://schemas.openxmlformats.org/package/2006/relationships">
<Relationship Id="R522c7c9989a04964" Target="/ppt/slideLayouts/slideLayout8.xml" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/slideLayout"/>
<Relationship Id="rId5" Target="/ppt/media/image2.bin" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image"/>
</Relationships>
两个差异,我认为如下:
-
这个
image2.bin
我想我可以追溯到一个1x1像素的自选图形“对象”,它出现在一些幻灯片母版上。我从每个幻灯片主控器中手动删除了它所在的位置,并重新整理了我的模板PPTX文件。
-
幻灯片缺少rel
身份证件
回到幻灯片布局,似乎很容易。我向openxmlutils类添加了一些扩展方法,并修改了
_insertNewSlide
方法如下:
private void _insertNewSlide(PresentationPart presentationPart, string layoutName)
{
Slide slide = new Slide();
SlidePart slidePart = presentationPart.AddNewPart<SlidePart>();
slide.Save(slidePart);
SlideMasterPart slideMasterPart = presentationPart.SlideMasterParts.FirstOrDefault();
SlideLayoutPart slideLayoutPart = slideMasterPart.GetSlideLayoutPartByLayoutName(layoutName); // extension method
/* ensure we added the rel ID to this part */
slidePart.AddPart<SlideLayoutPart>(slideLayoutPart, slideMasterPart.GetIdOfPart(slideLayoutPart));
slidePart.Slide.CommonSlideData = (CommonSlideData)slideLayoutPart.SlideLayout.CommonSlideData.Clone();
slidePart.CloneSlideLayout(slideLayoutPart); // extension method
presentationPart.AppendSlide(slidePart); // extension method
}
我在中添加了以下扩展方法
openxmlutils.cs软件
以下内容:
public static void CloneSlideLayout(this SlidePart newSlidePart, SlideLayoutPart slPart, string id)
{
// creates a Slide from a SlideLayout
/* ensure we added the rel ID to this part */
newSlidePart.AddPart(slPart, id);
using (Stream stream = slPart.GetStream()) { newSlidePart.SlideLayoutPart.FeedData(stream); }
newSlidePart.Slide.CommonSlideData = (CommonSlideData)slPart.SlideLayout.CommonSlideData.Clone();
foreach (ImagePart iPart in slPart.ImageParts)
{
newSlidePart.AddPart<ImagePart>(iPart, slPart.GetIdOfPart(iPart));
}
}
public static uint GetNextSlideId(this SlideIdList slideIdList)
{
uint nextId;
uint maxId = GetMaxSlideId(slideIdList);
if (maxId == 0)
{
// Slide Id must be >= 256
nextId = 256;
}
else
{
nextId = maxId++;
}
return nextId;
}
public static uint GetMaxSlideId(this SlideIdList slideIdList)
{
// find the highest id
uint maxSlideId = 0;
if (slideIdList.ChildElements.Count() > 0)
maxSlideId = slideIdList.ChildElements
.Cast<SlideId>()
.Max(x => x.Id.Value);
return maxSlideId;
}
public static SlideLayoutPart GetSlideLayoutPartByLayoutName(this SlideMasterPart slideMasterPart, string layoutName)
{
return slideMasterPart.SlideLayoutParts.SingleOrDefault
(sl => sl.SlideLayout.CommonSlideData.Name.Value.Equals(layoutName, StringComparison.OrdinalIgnoreCase));
}
public static void AppendSlide(this PresentationPart presentationPart, SlidePart newSlidePart)
{
SlideMasterPart slideMasterPart = presentationPart.SlideMasterParts.FirstOrDefault();
SlideLayoutPart slideLayoutPart = slideMasterPart.GetSlideLayoutPartByLayoutName(layoutName);
Slide slide = new Slide( );
SlidePart slidePart = presentationPart.AddNewPart<SlidePart>();
slide.Save(slidePart);
string id = slideMasterPart.GetIdOfPart(slideLayoutPart);
slidePart.CloneSlideLayout(slideLayoutPart, id);
presentationPart.AppendSlide(slidePart);
}
实现了这些更改后,我可以从主控形状成功地制作“一个内容”幻灯片,它看起来像
最
其他布局的输出也都是正确的,但是如果我尝试为每个幻灯片布局创建一个实例,仍然有一个“修复”问题需要隔离。
