How to resave images existing on disc in DM 3.4 (Force a replacement.) - save

Question

Try to do some image edit (add text and scale bar) and then automatically save/replace the original image, the codes work well with DM 2.0 and previous verison, but it does not work with 3.4 and 3.0, it shows " the process can not access the file because it is being used by another process". Is there any other way to do this with 3.4 and 3.0? thx
image front:=getfrontimage()
string imgname=getname(front)
string handler = "Gatan 3 Format"
ImageDocument doc = GetFrontImageDocument()
string thispath=pathconcatenate(currentdirectory, imgname)
doc.ImageDocumentSaveToFile( handler, thispath)

You can not save a file to a file-name of a currently opened file. Instead, you want to "re-save" your opened file. The easiest way to do that would be
image img := GetFrontImage()
img *= -1 // Just something to modify the image
img.Save()
If you want to do the same with an ImageDocument instead, it would be
imageDocument doc = GetFrontImageDocument()
doc.ImageDocumentSave(1)
The parameter in the command can either be:
0 = Always save, never prompt (Use linked location or folder of DigitalMicrograph.exe if not linked.)
1 = Save without prompting, if already linked to file, else prompt
2 = Always prompt
The following commands can also be useful when working with files and imageDocuments:
image img := GetFrontImage()
imageDocument doc = img.ImageGetOrCreateImageDocument()
Result( "\n Image ["+img.ImageGetLabel()+"] " )
if ( doc.ImageDocumentIsLinkedToFile() )
Result( "currenlty linked to:" + doc.ImageDocumentGetCurrentFile() )
else
Result( "not linked to a file." )
