About ReplacePicture method

[qylwhetc]

What I hope is that the ReplacePicture method can be implemented in Document, Container, and Paragraph, and that the executed new Picture will be placed in the original Picture's position, Just like ReplaceText。

My needs stem from:
There is a table with multiple columns in the template, and a certain row that needs to be replaced with Picture or text fields

dim txt="..."
row.ReplaceText(New StringReplaceTextOptions With {.SearchValue = "<txt>", .NewValue = txt}) 

This is great.

But the code to replace the Picture must be as follows: row.Paragraph (idx), idx is difficult to determine

Dim pNew = img.CreatePicture(100, 100)
Dim pOld = row.Pictures(0) '0...，easy to determine
'row.ReplacePicture(pOld, pNew)  'I hope,but error...
Dim idx = xxx	''no easy； Associate with template
row.Paragraphs(idx).ReplacePicture(pOld, pNew) 'replace(remove pOld) and  placed in Paragraphs(idx),not pOld's position

Thank you!

Hi,

Thank you for the suggestion. We will look into adding this feature.

In the meantime, could you add the following to detect which paragraph in your row contains the old picture and then replace the oldPicture with the new one:

var paragraphContainingOldPicture = row.Paragraphs.FirstOrDefault( paragraph => paragraph.Pictures.FirstOrDefault( picture => picture.Id == oldPicture.Id ) != null );
if( paragraphContainingOldPicture != null )
{
paragraphContainingOldPicture.ReplacePicture( oldPicture, newPicture );
}

Thanks

Dim pNew = img.CreatePicture(100, 100)
Dim pOld = row.Pictures(0)
'row.ReplacePicture(pOld, pNew)  'I hope,but error...
'Dim idx = xxx	'' Associate with template
'row.Paragraphs(idx).ReplacePicture(pOld, pNew)
'
'find Paragraphs(idx)
Dim paragraph= row.Paragraphs.FirstOrDefault(Function(p) p.Pictures.FirstOrDefault(Function(pic) pic.Id = pOld.Id) IsNot Nothing)
If paragraph IsNot Nothing Then
    paragraph.ReplacePicture(pOld, pNew)
End If

Ok!
Thanks

Hi，
I could have used row.ReplaceTextWithObject solves the problem, but replacing text with picture cannot be formatted in the template;
Still row.ReplacePicture is good;
Looking forward to providing in doc, table, row，and cell，Just like in the Paragraph.

Thank you

Hi,
thank you for reporting this.
The issue has been found and the fix will be part of the next release.
In the meantime, if you have access to the code, you can go in file Xceed.Document.NET/Src/Document.cs,
In method : public override Paragraph InsertParagraph( Paragraph p )
dans replace :
p.PackagePart = this.PackagePart; return base.InsertParagraph( p );
with:
var newParagraph = base.InsertParagraph( p ); newParagraph.PackagePart = this.PackagePart; return newParagraph;

Thank you

hi！ Following your guidance, I modified the code: //Xceed.Document.NET\Src\Document.cs public override Paragraph InsertParagraph(Paragraph p) { // copy paragraph's pictures and styles. this.InsertParagraphPictures(p); this.InsertParagraphStyles(p); //p.PackagePart = this.PackagePart; //return base.InsertParagraph( p ); var newParagraph = base.InsertParagraph(p); newParagraph.PackagePart = this.PackagePart; return newParagraph; } public override Paragraph InsertParagraph(int index, Paragraph p) {         //...Should it also be modified? return returnParagraph; } Later recompiled, successful； Afterwards, in the example, it was still incorrect, that is, why did the Picture in the original p0 disappear? //Xceed.Words.NET.Examples\Samples\Paragraph\ParagraphSample.cs public static void AddObjectsFromOtherDocument() { Console.WriteLine("\tAddObjectsFromOtherDocument()"); // Load a template document. using (var templateDoc = DocX.Load(ParagraphSample.ParagraphSampleResourcesDirectory + @"Template.docx")) { // Create a document. using (var document = DocX.Create(ParagraphSample.ParagraphSampleOutputDirectory + @"AddObjectsFromOtherDocument.docx")) { // Add a title. document.InsertParagraph("Adding objects from another document").FontSize(15d).SpacingAfter(50d).Alignment = Alignment.center; var p0 = templateDoc.Paragraphs[0]; var n00 = p0.Pictures.Count; //1 var p1 = document.InsertParagraph(p0); var n0 = p0.Pictures.Count; //0,why? disappear??   (I also hope to clone p0 in a loop) var n1 = p1.Pictures.Count; //1 Debug.WriteLine($"Pictures:{n0},{n1}"); //... // Get the image from the other document. var pictureToAdd = templateDoc.Pictures.FirstOrDefault();//null // Add the image in the new document. var newImage = document.AddImage(pictureToAdd.Stream);//error var newPicture = newImage.CreatePicture(pictureToAdd.Height, pictureToAdd.Width); p.AppendPicture(newPicture);     //... document.Save(); } } } How to solve it? thank you.

Hi,

You are right !
Here's a temporary workaround until a valid fix is implemented.
Go in file Xceed.Document.NET/Src/Document.cs,
in method : public override Paragraph InsertParagraph( Paragraph p )
and replace its content with:
` var clonedParagraph = new Paragraph( p.Xml );
clonedParagraph.Document = p.Document.Copy();
clonedParagraph.PackagePart = p.PackagePart;

this.InsertParagraphPictures( clonedParagraph );
this.InsertParagraphStyles( clonedParagraph );

var updatedParagraph = clonedParagraph.Document.Paragraphs.First( paragraph => paragraph.StartIndex == p.StartIndex );

var newParagraph = base.InsertParagraph( updatedParagraph );
newParagraph.PackagePart = this.PackagePart;

return newParagraph;`

We will try to add a uniform fix for the next release.
Thank you
