Does the bitmap header contain information about how to display the image. like for example flipX, flipY properties etc ?
According to http://www.fileformat.info/mirror/egff/ch03_03.htm there are more than one type of bitmap’s. The bitmap created by C# is it a windows bitmap or something else ?
No, flipX and flipY properties don’t make a lot of sense for a bitmap. Bitmap files are device independent formats that store raster 2D graphics—it contains pixel data. You can display it however you want; why should that information be embedded into the file? None of the file structures you linked to contain such properties.
Use the
Image.RotateFlipmethod to change how it is displayed.Whose implementation of the .NET Framework are you interested in? Microsoft’s? It uses a Windows bitmap, defined either through a
BITMAPINFOHEADERstructure or the extended version,BITMAPV5HEADER, all carefully documented here.
