WriteArray Method

In This Topic

Description

Writes object into a byte array (analogous to WriteFile)

Syntax

Visual Basic
Public Function WriteArray( _ ByVal isPart10 As Boolean, _ Optional ByVal TransferSyntax As Variant, _ Optional ByVal Quality As Variant _ ) As Variant

Visual Basic

Public Function WriteArray( _
   ByVal isPart10 As Boolean, _
   Optional ByVal TransferSyntax As Variant, _
   Optional ByVal Quality As Variant _
) As Variant

Parameters

isPart10: If TRUE, a blank 128 byte header, DICM marker, and meta-header are written at the start of the file, and an appropriate transfer syntax is used, as below.
If FALSE, the file is written in the unofficial, but common format, with no header, and using the little-endian implicit VR transfer syntax.
TransferSyntax: Specifies the full UID of the transfer syntax with which the file is to be saved when Part 10 format is used. If omitted, the little-endian explicit VR transfer syntax is used. For details of the currently supported syntaxes, see the conformance entry.
Quality: The quality factor to be used.

Remarks

Quality is specific to the compression method being used, and is ignored for non-compressed or lossless JPEG transfer syntaxes. For Lossy JPEG, it is an integer in the range 1-100, the higher the number, the better the quality (and the larger the file) , and for JPEG 2000 lossy, it is a compression ratio. Other compression methods may use this for other purposes in the future.
Data may be read back by the corresponding ReadArray method.
