I tried converting a 24bit TIFF image to 32bit PNG.
         L_INT nRet = L_FileConvert( (L_TCHAR*)outputFilePath,
                        (L_TCHAR*)outputPNGFilePath,
                          FILE_PNG,
                        0, 0, 32, 0, NULL, NULL, NULL );
The image is created with success and the size is appropriate. But there is no image and is completely transparent. I think this is a bug. Has it been fixed in some release or is there something we can do to overcome the problem.I have attached the tiff file for reference.

thanks

No, it's not a bug. Windows Picture and Fax Viewer only supports a limited set of TIFF formats. It can't read 32bit TIF images. If you open up the converted TIF in our demos you will see that it loads it fine.
