Public Methods

Method	Description
DetermineImageType ( Stream imgData ) : SupportedExtensions	Determines image type via headers. Keeps stream position.
FindFormatInString ( string stringWithFormatInIt ) : ImageEngineFormat	Searches for a format within a string. Good for automatic file naming.
GetBlockSize ( ImageEngineFormat format ) : int	Gets block size of DDS format. Number of channels if not compressed. 1 if not a DDS format.
GetCompressedSize ( int numMipmaps, ImageEngineFormat format, int width, int height ) : int	Calculates the compressed size of an image with given parameters.
GetExtensionOfFormat ( ImageEngineFormat format ) : string	Gets file extension of supported surface formats. Doesn't include preceding dot.
GetSupportedExtensions ( bool addDot = false ) : List	Get list of supported extensions in lower case.
GetSupportedExtensionsDescriptions ( ) : List	Get descriptions of supported images. Generally the description as would be seen in a SaveFileDialog.
GetSupportedExtensionsForDialogBox ( ) : List	Get list of filter strings for dialog boxes of the Supported Images.
GetSupportedExtensionsForDialogBoxAsString ( ) : string	Gets list of filter strings for dialog boxes already formatted as string.
GetUncompressedSize ( int topWidth, int topHeight, int numChannels, bool inclMips ) : int	Gets uncompressed size of image with mipmaps given dimensions and number of channels. Assume 8 bits per channel.
IsAlphaPresent ( System.Windows.Media.PixelFormat format ) : bool	Determines if alpha channel COULD be present in given format.
IsBlockCompressed ( ImageEngineFormat format ) : bool	Determines if format is a block compressed format.
IsExtensionSupported ( string filePath, List supported = null ) : bool	Determines if file has a supported extension.
IsFormatMippable ( ImageEngineFormat format ) : bool	Determines if given format supports mipmapping.
MaxNumberOfChannels ( ImageEngineFormat format ) : int	Gets maximum number of channels a format can contain. NOTE: This likely isn't actually the max number. i.e. None exceed four, but some are only one or two channels.
ParseExtension ( string extension ) : SupportedExtensions	Gets file extension from string of extension.

Method Details

DetermineImageType() public static method

Determines image type via headers. Keeps stream position.

public static DetermineImageType ( Stream imgData ) : SupportedExtensions
imgData	Stream	Image data, incl header.
return	SupportedExtensions

FindFormatInString() public static method

Searches for a format within a string. Good for automatic file naming.

public static FindFormatInString ( string stringWithFormatInIt ) : ImageEngineFormat
stringWithFormatInIt	string	String containing format somewhere in it.
return	ImageEngineFormat

GetBlockSize() public static method

Gets block size of DDS format. Number of channels if not compressed. 1 if not a DDS format.

public static GetBlockSize ( ImageEngineFormat format ) : int
format	ImageEngineFormat	DDS format to test.
return	int

GetCompressedSize() public static method

Calculates the compressed size of an image with given parameters.

public static GetCompressedSize ( int numMipmaps, ImageEngineFormat format, int width, int height ) : int
numMipmaps	int	Number of mipmaps in image. JPG etc only have 1.
format	ImageEngineFormat	Format of image.
width	int	Width of image (top mip if mip-able)
height	int	Height of image (top mip if mip-able)
return	int

GetExtensionOfFormat() public static method

Gets file extension of supported surface formats. Doesn't include preceding dot.

public static GetExtensionOfFormat ( ImageEngineFormat format ) : string
format	ImageEngineFormat	Format to get file extension for.
return	string

GetSupportedExtensions() public static method

Get list of supported extensions in lower case.

public static GetSupportedExtensions ( bool addDot = false ) : List
addDot	bool	Adds preceeding dot to be same as Path.GetExtension.
return	List

GetSupportedExtensionsDescriptions() public static method

Get descriptions of supported images. Generally the description as would be seen in a SaveFileDialog.

public static GetSupportedExtensionsDescriptions ( ) : List
return	List

GetSupportedExtensionsForDialogBox() public static method

Get list of filter strings for dialog boxes of the Supported Images.

public static GetSupportedExtensionsForDialogBox ( ) : List
return	List

GetSupportedExtensionsForDialogBoxAsString() public static method

Gets list of filter strings for dialog boxes already formatted as string.

public static GetSupportedExtensionsForDialogBoxAsString ( ) : string
return	string

GetUncompressedSize() public static method

Gets uncompressed size of image with mipmaps given dimensions and number of channels. Assume 8 bits per channel.

public static GetUncompressedSize ( int topWidth, int topHeight, int numChannels, bool inclMips ) : int
topWidth	int	Width of top mipmap.
topHeight	int	Height of top mipmap.
numChannels	int	Number of channels in image.
inclMips	bool	Include size of mipmaps.
