IMcStreamGetCompressionTypes Method

This method queries the Registry entries of McStream format indicated by "format", in the access mode indicated by "Mode", and fills the "descriptions" VARIANT with a safe-array of BSTR's with compression names, and a corresponding safe array stored in the VARIANT "ids" with the mccsCompression numbers in the same order as descriptions. The VARIANT image argument is either the image to query, an image type, or an image QuickType. This is to ensure that the compression schemes available support the data type of the image you wish to save.

Function GetCompressionTypes ( 
	Format As String,
	Mode As mcfmFileMode,

	<OutAttribute> ByRef descriptions As Object,
	<OutAttribute> ByRef ids As Object
