The flags for a sub-format identify additional settings for an encoder that can be changed through the encoder property bag. Sub-format flags are obtained by calling the IWICLeadBitmapEncoder::GetSubformatFlags method. The following table summarizes the list of sub-format flags and their meaning:

The SubFormat is one of the property bag items of the LEAD Bitmap Encoder Property Bag of LEAD encoder objects. When creating any of the LEAD encoders, the SubFormat property bag item defaults to one of the constants in this enumeration. Every LEAD encoder supports one or more sub-formats in the WICLeadSubformat enumeration. For more information, refer to IWICLeadBitmapEncoder::GetSubFormats.

For an example, refer to the IWICLeadBitmapEncoder::GetSubFormats method.
