Why WPicture.Dispose() doesn't dispose the loaded picture?
In our older versions of Essential studio (before 10.3.0.53) we have preserved System.Drawing.Image instance as a reference in WPicture and PictureWatermark. So it is necessary to dispose the System.Drawing.Image instance preserved in the WPicture object before deleting the image file. Whereas in later versions (from 10.3.0.53) we have optimized the main memory utilization by preserving single reference of an image for the entire document as image bytes instead of System.Drawing.Image instance. Kindly dispose the System.Drawing.Image instance explicitly before trying to delete the image file in later versions.
Below code snippets demonstrates how to delete the image file after setting it as picture watermark in Word documents.
C#:
PictureWatermark watermark = new PictureWatermark(); //Gets the image file FileInfo imageFile = new FileInfo(imagePath); //Loads image from file system Image image = Image.FromFile(imagePath); //Sets the image to the PictureWatermark watermark.Picture = image; document.Watermark = watermark; //Dispose the image image.Dispose(); //Delete the image file imageFile.Delete();
VB:
Dim watermark As New PictureWatermark() ‘Gets the image file Dim imageFile As New FileInfo(imagePath) ‘Loads image from file system Dim image As Image = Image.FromFile(imagePath) ‘Sets the image to the PictureWatermark watermark.Picture = image document.Watermark = watermark ‘Dispose the image image.Dispose() ‘Delete the image file imageFile.Delete();
Below code snippets demonstrates how to delete the image file after loading it as picture in Word documents.
C#:
//Gets image file FileInfo imageFile = new FileInfo(imagePath); //Loads image from file system Image image = Image.FromFile(imagePath); //Appends picture to the paragraph IWPicture picture = paragraph.AppendPicture(image); //Dispose the image image.Dispose(); //Delete the image file imageFile.Delete();
VB:
Dim watermark As New PictureWatermark() ‘Get image file Dim imageFile As New FileInfo(imagePath) ‘Loads image from file system Dim image As Image = Image.FromFile(imagePath) ‘Appends picture to the paragraph Dim picture As IWPicture = paragraph.AppendPicture(image); ‘Dispose the image image.Dispose() ‘Delete the image file imageFile.Delete();
