Acad2010 thumbnail

Anonymous — Fri, 23 Apr 2010 13:57:00 GMT

I have a programm in Autocad 2009 that change something in a series of Dwg
and when i make closeandsave(filename) store also the thumbnail.
I see the preview in explorer.
Now i have install Acad2010 and recompile the program with the new
library,but the closeandsave(filename) don't store the thumbnail.
Some help?
thanks in advance.

In AutoCAD 2010 or later, you can call the
Document's CreatePreviewImage() method,
and assign the result to the Database's
ThumbnailBitmap property.

Yes,i have see it and i have already try it,but when i save in Acad i obtain a thumbnail with white background color (in explore) when i create thumbnail by program with the function "CreatePreviewImage" i obtain a thumbnail indefinite and with black background color like my background color in Acad.
Any other suggestion?
Thanks and good week-end.

The thumbnail stored in the database should be the
same as the one returned by CapturePreviewImage().

It's possible that the background color is manipulated
when Explorer requests the thumbnail.

If you're using AutoCAD 2011, then don't bother with this method.

Autodesk apparently has broken this method an if you call it
AutoCAD will stop responding.

No,i use Acad2010.
My Background color in Acad2010 is black like in Acad2009 and if i save the
drawing by Acad the thumbnail that i see is correct.
If i save the same drawing by .net program i don't obtain the same thing.
Thank's.

version Acad2009:

doc.LockDocument.Dispose()

doc.CloseAndSave(NomeDwg)

doc.Dispose()

I have replace it in Acad2010 version with :
'Dim bm As Bitmap = doc.CapturePreviewImage(128, 102) Not used

'doc.Database.ThumbnailBitmap() = bm
Not used

doc.Database.SaveAs(NomeDwg, True, AcDbs.DwgVersion.Current,
doc.Database.SecurityParameters)

doc.LockDocument.Dispose()

doc.CloseAndDiscard()

doc.Dispose()

***********************************************************
Now all work fine like in Acad2009 version.

Thank's Tony
