Generate Bitmap Preview Of Btw File Follow
I have a .net production management system that uses Bartender ActiveX API to modify formats at runtime. This application stores the BTW file contents in the database and when editing a process or product record I show a bitmap preview of the bartender file. Or at least I used to. I was using a C++ library that I created 10 years ago that relied on the "BarTender.ThumbnailExtension" COM object to retrieve the preview image. I actually found most of the source on a Seagull CD or something like that, I can't remember but I know I didn't develop it from scratch.
Development for my application stopped for a few years and during that period we upgraded to Windows 7 and upgraded Bartender editions as well. My BTW preview component no longer works.
Before I spend the time to try to debug and fix this component I thought I'd ask if there was another way to generate a raster preview of a BTW file? I've asked Seagull over the years for a supported .Net component/source code and they've never delivered.
Anyone here have a trick or method to generate a raster preview of a BTW file?
In case anyone is interested I've added the C++ library source code in the attached zip
