Sizing Image inside Word Document using Openxml SDK .Net c#
问题
如何获得Word文档的宽度？以及实现此任务的最佳方法是什么？
英文:
I added an image to my generated word document using openxml sdk, but iam not able to size that image to word document full width respecting the image ratio.
How can i get the word document width? And what is the best aproach to achieve this task!?

我现在以这种方式解决了这个问题，并且它运行正常：
// 缩小图像
SectionProperties？ sectionProperties = null;
PageSize？ pageSize = null;
long pageWidth = 0;
if (main.Document.Body is { })
sectionProperties = main.Document.Body.GetFirstChild
if (sectionProperties is { })
pageSize = sectionProperties.GetFirstChild
if (pageSize is { Width: { } } && pageSize is { Height: { } })
pageWidth = pageSize.Width;
if (pageWidth > width) {
var sizeFactor = pageWidth / width;
width = (int)pageWidth;
height = (int)(sizeFactor * height);
}
double englishMetricUnitsPerInch = 914400;
double pixelsPerInch = 96;
double factor = englishMetricUnitsPerInch / pixelsPerInch;
/*
- MS-Docs（OpenXml SDK，PageSize 类）
- 此输出说明此部分中的所有页面必须为11907点的二十分之一宽度（11907点的二十分之一 = 8.269“）和16839点的二十分之一高度（16939点的二十分之一 = 11.694“）。示例结束]
*/
double emuWidth = (width * factor) / 20;
double emuHeight = (height * factor) / 20;
在绘图元素内部：
Extent = new() {
Cx = (Int64Value)emuWidth,
Cy = (Int64Value)emuHeight
},
英文:
I solved it that way now and it works fine:
// Scaling down the Image
SectionProperties? sectionProperties = null;
PageSize? pageSize = null;
long pageWidth = 0;
if (main.Document.Body is { })
sectionProperties = main.Document.Body.GetFirstChild<SectionProperties>();
if (sectionProperties is { })
pageSize = sectionProperties.GetFirstChild<PageSize>();
if (pageSize is { Width: { } } && pageSize is { Height: { } })
pageWidth = pageSize.Width;
if (pageWidth > width) {
var sizeFactor = pageWidth / width;
width = (int)pageWidth;
height = (int)(sizeFactor * height);
}
double englishMetricUnitsPerInch = 914400;
double pixelsPerInch = 96;
double factor = englishMetricUnitsPerInch / pixelsPerInch;
/*
* MS-Docs (OpenXml SDK, PageSize Class)
* This output states that all pages in this section must be 11907 twentieths of
* a point wide (11907 twentieths of a point = 8.269") and 16839 twentieths of a
* point high (16939 twentieths of a point = 11.694"). end example]
*/
double emuWidth = (width * factor) / 20;
double emuHeight = (height * factor) / 20;
The inside the drawing element:
Extent = new() {
Cx = (Int64Value)emuWidth,
Cy = (Int64Value)emuHeight
},
