Read / Write Gif ActiveX

[themaddis]

Hi there. I need some help.

I am writing a program in VB6 where i need to extract each frame from an animated gif, watermark each frame, then recompile the gif back to an animated gif.

The reason for this is i want to be able to watermark any animated gifs i pass through my program.

At the moment i am using AniGif.ocx which will allow me to view and extract each frame from the gif.

I am then using watermark factory pro to watermark each frame. I have looked at MakeGif 1.5 as it has command line support which i can send the details of the watermarked frames to recompile the gif, but an reluctant to buy, as i would rather have a control to do this.

I have looked far and long to try and find an activeX control that will alow me to both Read and write gif frames.

Does anyone have any info/ know where i can find such a control?

Please help.

Thanks Matt Addis

Doubtful you will find one that is free due to the copyright on the LZW compression that Unisys requiring a licence fee from developers.

Surely not yet, may be the patent if any ...

I believe it was patent not copyright that applied to LZW. The patent has expired - see
