SaveJLSNear Property

Description

Gets and sets the error tolerance for near-lossless compression for JPEG-LS.

Property Type

Read-write property

Syntax

Visual Basic
Public Property SaveJLSNear As Long

Return Type

A long value which represents the error tolerance for near-lossless compression.

Valid range is zero (lossless), one (near lossless) to 255 (very lossy).

Remarks

Generally, Near should be set to zero or a small positive number, perhaps 4 or 5 with higher numbers leading to ugly streaking artifacts. The Near parameter defines the error tolerance for near-lossless compression. If Near = 0, compression will be lossless and the reconstructed image after decompression will be identical to the original. If Near > 0, each pixel of the reconstructed image will differ from the original by no more than the value of Near. The value of MaxValue affects the maximum value of Near which will be either 255 or MaxValue/2 (rounded up) whichever is lower.
