Parameters

id

ID of the JPEG marker. The JPEG markers are uniquely identified by a byte value. Possible values are 1 to 254. (0 and 255 are not allowed.)

data

A pointer to the unmanaged memory buffer containing the marker data. This parameter is valid only if dataLength is > 0.

dataLength

Size in bytes of the JPEG marker (data). The size will be less than 65535. If this value is 0, then the marker does not have any extra data and data should be ignored.

transform

Flags that indicate the transform to be performed. These are the same flags passed to the RasterCodecs.Transform method.
