I found many support that used the similar logic to replaec text with image. But when I tried to use the same code, I got the following error
Argument 2: cannot convert from ‘ReplaceWithImageEvaluator’ to ‘string’
Argument 3: cannot convert from ‘bool’ to ‘Aspose.Words.Replacing.FindReplaceOptions’
would it be any new coding method for the function call Replace?
To ensure a timely and accurate response, please ZIP and attach the following resources here for testing:
As soon as you get these pieces of information ready, we will start investigation into your scenario and provide you more information.
How about providing ANY code method that could replace a text with an image? As far as I can tell, the example code provided is not supported and asking for more information when you obviously don’t have a solution is unacceptable.
To clarify, this post does not work as the method signature implemented doesn’t exist at all:

@Sunhillow You ca easily replace text with an image using IReplacingCallback. Please see the following code example:
Document doc = new Document(@"C:\Temp\in.docx");
FindReplaceOptions options = new FindReplaceOptions();
options.ReplacingCallback = new ReplaceEvaluatorFindAndReplaceWithImage();
doc.Range.Replace("[ImagePlaceholder]", @"C:\Temp\img.png", options);
doc.Save(@"C:\Temp\out.docx");
private class ReplaceEvaluatorFindAndReplaceWithImage : IReplacingCallback
{
/// <summary>
/// This method is called by the Aspose.Words find and replace engine for each match.
/// </summary>
ReplaceAction IReplacingCallback.Replacing(ReplacingArgs e)
{
Document doc = (Document)e.MatchNode.Document;
// This is a Run node that contains either the beginning or the complete match.
Node currentNode = e.MatchNode;
// The first (and may be the only) run can contain text before the match,
// in this case it is necessary to split the run.
if (e.MatchOffset > 0)
currentNode = SplitRun((Run)currentNode, e.MatchOffset);
// This array is used to store all nodes of the match for further deleting.
List<Run> runs = new List<Run>();
// Find all runs that contain parts of the match string.
int remainingLength = e.Match.Value.Length;
while (
remainingLength > 0 &&
currentNode != null &&
currentNode.GetText().Length <= remainingLength)
{
runs.Add((Run)currentNode);
remainingLength -= currentNode.GetText().Length;
// Select the next Run node.
// Have to loop because there could be other nodes such as BookmarkStart etc.
do
{
currentNode = currentNode.NextSibling;
} while (currentNode != null && currentNode.NodeType != NodeType.Run);
}
// Split the last run that contains the match if there is any text left.
if (currentNode != null && remainingLength > 0)
{
SplitRun((Run)currentNode, remainingLength);
runs.Add((Run)currentNode);
}
// Insert an image at place of matched text.
DocumentBuilder builder = new DocumentBuilder(doc);
builder.MoveTo(runs[runs.Count - 1]);
// Here we suppose that replacement is a path to an image.
// You can use another approach to get an image.
builder.InsertImage(e.Replacement);
// Delete matched runs
foreach (Run run in runs)
run.Remove();
// Signal to the replace engine to do nothing because we have already done all what we wanted.
return ReplaceAction.Skip;
}
private static Run SplitRun(Run run, int position)
{
Run afterRun = (Run)run.Clone(true);
run.ParentNode.InsertAfter(afterRun, run);
afterRun.Text = run.Text.Substring(position);
run.Text = run.Text.Substring((0), (0) + (position));
return afterRun;
}
}
The code replaces "[ImagePlaceholder]" text with an image, which path is passes as a replacement.
