So, you mean that I need to copy and paste OpenCV jpeg (c++ and .h) files into
FLTK jpeg folder.
Means I need to override all opencv jpeg files over fltk jpeg ? or I need to
change the path of jpeg folder in Additional Include Directories.. Am I right ?
By the way I solved in this way, It is working perfectly.
Oimg1 = cvLoadImage(Image1, 0);
if(Oimg1 == NULL) {return 0;}
unsigned char* imgdata1 = new unsigned
char[Oimg1->width*Oimg1->height*Oimg1->nChannels];
GetImageDataFromOpenCV(Oimg1, imgdata1);
Fl_RGB_Image *rgb_img0 = new Fl_RGB_Image((const uchar *) imgdata1,
Oimg1->width, Oimg1->height, Oimg1->nChannels);
FLTKimg[0] = (Fl_Shared_Image *)rgb_img0;
