Large bitmap fails to convert to JPEG

I have a large 45Mb bitmap to convert to JPEG when using a tJPEGImage when
using the assign statement.  Does any one know the reason, is there a
soolution??

If the problem is JPEG Error #36, then you can try the Intel JPEG Library
(now being replaced) for which I've written a simple interface at:

However, if you have Delphi 6, JPEG Error #36 should be fixed!

Cheers,

Also note that you may run into all kinds of problems with large bitmaps on
Windows 95/98/ME. See Earl F. Glynns site for the huge bitmap example.

Can you reproduce the error on NT/Win2000/XP?

Re:Large bitmap fails to convert to JPEG


Even a large TBitmap like that will fail on many systems...

There are a few 3rd party sources for relibably dealing with large bitmaps
and JPEGS.

We wrote our own...
