Your support forums website lost my posting.
I created the following private posting in the "PDF Product Family"
on Wednesday at approx 3:20pm EDT (GMT -5):
http://www.aspose.com/community/forums/335515/out-of-memory-or-slow-performance-using-extractimage-on-large-pdf-file/showthread.aspx#335515
.Now, I don't see my post at all (even though I'm logged in). The above link goes to a completely different link.
I will now spend 30 minutes re-creating the post.
I pay good money for your support, and your broken support forums are wasting my time.
