VB Forum / General 2 / August 2004Saving images in GIF format
Does anyone know of a dll that can be used to save an image directly into GIF format in VB 4? I'm looking for an API that can do the save in LZW compression mode. I understand Unisys's patent has now expired as of July, 2004. > Does anyone know of a dll that can be used to save an image directly > into GIF format in VB 4?

It's a free DLL which has GIF support recently added back in. You can download it on SourceForge. I have a wrapper class available on my site, but it's done for VB6. With some adjustment, you could probably get it going for VB4, but it might be easier to just pull out my Declares and scrap the rest or write your own. Also on my site is a compressor for GIF LZW. It'd probably be slow in VB4, but that sort of depends on the machine and on your use. You could try. Murphy www.ConstantThought.com Actually I'd just as soon avoid wrappers and just go with straight declares. Keep it simple. That's my philosophy. >> Does anyone know of a dll that can be used to save an image directly >> into GIF format in VB 4?

Keep it simple. That's my philosophy. All depends on your definition of simple and the problem at hand. Using a good wrapper class, you can easily accomplish many things in far fewer lines of application-specific code than if you could otherwise. And if you write fewer lines of code... there are fewer chances of making a mistake. But sure. Sometimes you just want the Declares. No one methodology is optimal for all problems. That's my philosophy. ;) Murphy www.ConstantThought.com |
