$this->image_lib->clear();
}
I get cropped image. But problem is don't get exact cropped image x,y coordinate problem
Please correct the coordinate
Use .offset()
to get the exacty x/y of your image.
The x1
is most likely the x1
of the mouse on the screen - so in this case 249 needs to be reduced by the x
of the image you're selecting.
Reduce the X values by the image's .offset().left
and the y values by .offset().top
and then send to php.
