Hello,
I was wondering if anyone knew how to redraw after altering the pixel array in
fltk, basically, I have:
..
Fl_JPEG_Image jpg("logo.jpg");
..
for(int i=0; i!=jpg.h()*jpg.w(); i++){
((uchar*)jpg.array)[3*i+1]=0;
((uchar*)jpg.array)[3*i+2]=0;
}
UI.ImageBox->set_changed();
UI.ImageBox->redraw();
I'm trying to only get the blue color to show up. I know that this change is
registering, because when I do the desaturation, it gets darker when I first
run it through this.
Any tips would be much appreciated!
Thanks.
