I am trying to convert a bmp file to a jpeg2000 file. I am using the following code:

void BmpToJp2(char *rutaBmp){
     CxImage image;
     const char *aux;
     aux=(rutaBmp+AnsiString(".bmp")).c_str();
     image.Load(aux, CXIMAGE_FORMAT_BMP);
     if (image.IsValid()){
           aux=(rutaBmp+AnsiString(".jp2")).c_str();
           bool ok=image.Save(aux,CXIMAGE_FORMAT_JP2);
           ok=image.Load(aux,CXIMAGE_FORMAT_JP2);
     }
}

The file seems perfectly saved cause the value of the variable ok after the saving operation is true, and the file in the hard disk is right. Then I try to load the file, and the result of ok var is false, but the program is not stopped. Then in another function I try again to load the j2p image and an interruption happens. I don't know why the file can not be loaded if it is saved properly.

Thank you.
Regards.
