See the code below.

If I pass an HDIB that has a resolution of 200x200, the Result below comes out at 300x300. How do I preserve the resolution when I load and manipulate the HDIB in TImageEnVect?

IEBitmap.CopyFromDIB(HDib);

Result := IEBitmap.CreateDIB;

I can't see how that could occur. Can you email us a small demo.

NOt sure how to do that since the DIB is created by a different third party software.

What's strange is that if the assign the DIB to a TBitmap and the use your CopyFromTBitmap it keeps the original resolution.

Hmmm, I've just re-checked the code and cannot see any issues. It also uses a TBitmap internally to retrieve the DIB.

Do you have a procedure or property that allow me to reset the resolution or find out what it is on the loaded DIB?

Hi

No, I'm afraid that is not possible with a DIB.
