Hi

Thanks for your inquiry.
Our Spire.Doc doesn't support inserting base64 data into Word directly. But you can save the base64 to image file, and then insert the image into Word using our Spire.Doc. Here is the code for your reference. If there is still any question, please feel free to write back.

Code: Select all

 
string[] str = base64Str.Split(',');
//convert base64 to image
byte[] imageBytes = Convert.FromBase64String(str[1]);
MemoryStream memoryStream = new MemoryStream(imageBytes, 0,imageBytes.Length);
memoryStream.Write(imageBytes, 0, imageBytes.Length);
Image image = Image.FromStream(memoryStream);
Document document = new Document();
//create a section
Section section = document.AddSection();
//create a paragraph
Paragraph paragraph = section.AddParagraph();
//append the image in document
paragraph.AppendPicture(image);
//save the document
document.SaveToFile("result.docx", FileFormat.Docx);

When getting OleObject then how to read the image in that oleObject .please suggest as soon as possible

[babalipatil]

DocOleObject docOle = dom as DocOleObject;
var GetType = docOle.ObjectType;
if (GetType == "ChemDraw.Document.6.0")
{
// how to convert ole object to image or bitmap
//how to get image data from oleobject

string base64 =Convert.ToBase64String(docOle.NativeData); // using this getting same native data for all images.
}

Hi

Thanks for your inquiry.
Kindly note that our Spire.Doc follows specification of the Microsoft Word. I did some investigations but didn't find the "ChemDraw.Document.6.0" file could be directly inserted into Word as OLE object. How did you do that? Could you please send us your word sample that contains the ChemDraw.Document.6.0 object to help us do further investigation? You could attach your file here or send it to us via email ([email protected]). Thanks in advance.

Hi

Thanks for your inquiry.
You can refer to the following code to export ole objects in your document as images. If there is any question, please feel free to write back.

Thank You...
But ole.OlePicture.Image // getting error because DocPicture does contain defination of Image

[lynn.zhang]

Hi

Thanks for your feedback.
Please note the Ole is an object, it will be presented in word in the form of a picture. And our Spire.Doc will parse the Ole object in the following structure (see attached screenshot), in fact, the image of DocOleObject is pointing to the DocPicture, hence, they have the same image data. This is not an error, it is determined by the internal analysis mechanism of our Spire.Doc. Hope I make it clear. If there is any misunderstanding, please feel free to write back.
