Can you answer the following questions:
1. which LEADTOOLS version (15, 16, etc.) and build number (DLL file version info) are you using?
2. How exactly are you using the CopyRect() function?
3. Does this happen with all files or only BMP files?
4. Can you send me the source BMP file in a ZIP or RAR file? (the image you attached is a PNG image not a BMP?

1. which LEADTOOLS version (15, 16, etc.) and build number (DLL file version info) are you using?

16.5 eval


2. How exactly are you using the CopyRect() function?

 LBitmapBase lbbTmp;

 nRet =lbbTmp.CopyRect((LBitmapBase&)(*m_cpAnnWnd),
          a_rtSel.left, a_rtSel.top, a_rtSel.right, a_rtSel.bottom);


3. Does this happen with all files or only BMP files?

only BMP file. I guess bitmap row order is the cause.

Is there any method LT16.5 for changing row order of bitmap?


4. Can you send me the source BMP file in a ZIP or RAR file? (the image you attached is a PNG image not a BMP?

see the attachment.

I have tried this at my side and I did not face the problem that you are describing, what is the return value of the CopyRect (nRet)?
Also, what is the build number (version info) of Ltkrnu.dll?

I checked your images, and they both have view perspective of Bottom-Left which makes the rectangle reversed.
To fix the issue you should take the view perspective into consideration. One way to do it without changing other parts of your code is to make the image Top Left by using LBitmapBase::ChangeViewPerspective.
