BMP to JPEG conversation

Hi all,
I want to convert BMP files into JPEG/JPG file because BMP files size is more. (around 1 MB. each) How can i convert them into JPEG programatically? Any API's? I want them in JPEG format as its size is almost 10 times less than BMP.
Help Me..

Does anyone else see this?

just keep in mind that BMP files are "lossless" and JPEG files are "lossy". That probably doesn't matter for your needs, but you should be aware of it in case it does.

Hi Phinds,
Can u explain it more clearly? What do u want to say?
"lossless" & "lossy"? Anyway, i can't afford 1MB for a single file. If i can convert it in JPEG format, it becomes less than even 50 kb. in size..
But i just want to do it programatically..
Help.

It solved my problem...
Anita..

:) I knew that would help. I've posted it many times before.

Hi all,
Sorry for opening this issue once again...
Actually i got the answer by post of MidgetsBro. The code is working fine. But that code uses a dll file for this. Can anyone knows how it can be done without using a dll file? Any solution?
please help..

JPEG is "lossy" means that it throws away some of the graphic information. That's how it is able to be so small. all the information isn't there. As long as the picture does not look fuzzy when you display it, there is no problem. Most web pages use JPEG except for very small images, which are GIF (no loss).

Why are DLLs a problem? MANY things in VB programming have to be done with DLLs. You should get used to using them

Take a look at this link. You have the source code, but its still in C++.

I doubt there is a way to do this without a DLL. VB wasn't made to allow users to create complex compression algorithms. C++ is better in that area, and that is most likely what this DLL was created in. You can search the net, but you will probably not find any code to do this in VB. Everything will be done in C or C++.
