Convert Graphics Format

[T. Sunil John]

How can I change the Graphic file format, i.e. bmp to jpg or gif or anything in VB.

Also Image control or Picture control in VB is not able to display graphics of 24bit color depth correctly are there any alternatives to this?

Thanks in advance for nay help or suggestion,
Infinite

If you want to convert from bmp to jpeg or vice versa have a look at this code

as far as gif are concerned I have no idea and I'd be careful about infringing copyright

enielezi:
you should email (or send a private message) to kingwgl or to any other that asked for it, not post a new thread all alone in vb forum with a request that seems really cryptic if not related to this thread...
