Is the IShellItemImageFactory interface, used for getting Vista/7 shell thumbnails, broken?

让人想犯罪 __ 提交于 2019-12-06 06:22:16
I want to use IShellItemImageFactory to retrieve the shell thumbnail of files. According to the MSDN docs, if I pass in a SIZE struct of 256x256, it should populate the HBITMAP parameter with a 256x256 bitmap, and if I use the SIIGBF_RESIZETOFIT flag, it should resize smaller thumbnails to 256x256. It doesn't. Instead, the result is a 256x256 bitmap with a small icon drawn in the middle. Okay, maybe that's just not what SIIGBF_RESIZETOFIT is supposed to do. But then, as I understand it, I should be able to use SIIGBF_BIGGERSIZEOK and specify a tiny size (say 1x1) and it should return the

Because of this one requirement, the system is running on Windows Server 2003 + IIS. I would prefer to have the system running on a Linux server, rather than MS, as I have far more experience in administering Linux systems than Windows and we have no other in-house technical

How to read embed thumbnail from jpeg images?

问题 I am writing a thumbnail viewer in c++. I first make use of EXIF information to retrive an image's thumbnail, but the thumbnail in the EXIF is bad, with black bands. So I want to get the jpeg's embedded thumbnail, how can I do this? Another question: does jpeg's embeded thumbnail equal to EXIF thumbnial? 回答1: If the EXIF thumbnail is bad, you can generate your own from the JPEG itself, without needing to completely decode the JPEG. Look for the source code for EPEG . It's part of the
