Description</sup>
Sets the type of GIF compression.

* Important note

GIF LZW compression has been disabled in TeeChart Pro AX v5 until the use and licensing of LZW has been completely clarified with Unisys. Unisys's position on LZW licensing has led us to the interim conclusion (unfortunately) that by not including LZW we protect ourselves and our customers against unexpected licensing battles with Unisys at a later stage. TeeChart continues to support GIF with RLE compression which is not subject to Unisys license.

For more information see: http://www.unisys.com/unisys/lzw/

We will be happy to discuss the issue with any customer who feels that they need to use LZW and to make a joint approach to Unisys to clarify the license position.

The image format PNG is superior in many respects to GIF with LZW, particularly in the case of TeeChart where animations are not exported. We recommend the use of PNG where possible.

EGIFCompressionOptions:

gcLZW = 0

gcRLE = 1

This version of TeeChart only supports RLE encoding. Please see note above.
