Aspose.Note fails to get Image's binary data

Aspose.Note Product Family
1

I found that Aspose.Note .NET version after 22.3.0 i.e. starting from 22.5.0 has issues regarding extracting images from OneNote files.

I have multiple samples where Aspose.Note when extracting image fails to get the correct binary data of the image. Image.Bytes yields the incorrect binary data for the image file, it outputs out a zip file.

Please check the snippet code below
Document oneNote = new Document(“OneNoteFile”);
var allImageNodes = doc.GetChildNodes();
using(var outStream = new FileStream(tempFile, FileMode.Create, FileAccess.ReadWrite, FileShare.Read))
outStream.Write(image.Bytes, 0, image.Bytes.Length);
contain_txt_printout.zip (545.8 KB)

If you check the tempFile then its a zip file not an image file.
Please find the file attached here:

@dunghnguyen,

I reproduced the issue using the latest version/fix: Aspose.Note for .NET v23.2. I found Aspose.Note does not get image’s binary data correctly from the OneNote document.
e.g.
Sample code:

Aspose.Note.Document onedoc = new Aspose.Note.Document("g:\\test2\\contain_txt_printout.one");
IList<Aspose.Note.Image> nodes = onedoc.GetChildNodes<Aspose.Note.Image>();
foreach (Aspose.Note.Image image in nodes)
{
        using (var outStream = new FileStream("g:\\test2\\out1" + image.FileName + ".png", FileMode.Create, FileAccess.ReadWrite, FileShare.Read))
         outStream.Write(image.Bytes, 0, image.Bytes.Length);
}
