02-02-2007, 15:30 viable@viacad.com Joined on 04-27-2005 Posts 2 Dithering Tricks I am working on an application and my customer is requesting a change.   They have found that in CorelDraw the Dither option allows you to control the intensity of the dither (CorelDraws terms).  What this seems to do is allow for areas of the image to become patches of solid color instead of the 'dots'.  How do I do this?  Thanks in advance I am using the VB 6.0 version (not .NET)    Report

To see each technique effect you can use our VB Main Demo as follows: 1. Load any colored image. 2. From Color menu select "Transform" then "Color Resolution" to open the color resolution dialog 3. From the Color Resolution dialog, you can check the dithering techniques. For code sample, please refer to the "ColorRes method" topic in the help file.

If you would like to ask our engineers to add it in the future, you can post a feature request using the following web page: http://www.leadtools.com/DevServices/Feature-Request.htm If you do that, please provide as much information about the requirements you have Adnan Ismail LEADTOOLS Technical Support    Report
