C# Class NContrib.Drawing.ImageSizeHelper

Public Methods

Method	Description
GetBmpImageSize ( Stream stream ) : Size	Reads the size of a BMP image from this stream at the current offset Rewinds the stream to where it started when finished
GetGifImageSize ( Stream stream ) : Size	Reads the size of a GIF image from this stream at the current offset Rewinds the stream to where it started when finished
GetImageSize ( Stream stream ) : Size	Tries to use the GNV fast image size checkers for JPEG, GIF, PNG, and BMP Uses .NET newing-up an Image object as a fallback
GetImageSize ( string imagePath ) : Size	Tries to use the GNV fast image size checkers for JPEG, GIF, PNG, and BMP Uses .NET newing-up an Image object as a fallback
GetJpegImageSize ( Stream stream ) : Size	Reads a JPEG image's dimensions and returns a Size object. Much faster than using the built in System.Drawing.Image class which loads the entire image into memory Rewinds the stream after reading.
GetPngImageSize ( Stream stream ) : Size	Reads the size of a PNG image from this stream at the current offset Rewinds the stream to where it started when finished
