I have an image of size 720x540, and the flash document holding it is 550x400. Ultimately, I want to be able to pan around the image and zoom in and out. This isn't the problem, but when using the startDrag function I want to set variable parameters, so basically, you can't pan where there isn't any image. I managed to code the actionscript such that when the image is at 100% you cannot pan outside of the image, however, when I changed this to become a variable to account for zooming in the result was the image stopped panning altogether (reverted the registration back to the point (0,0) when clicked.)

The method I tried (and failed using) is as follows:

code:

---

function pan(movieClip) {
    movieClip.onMouseDown = function () {
        set("x1", 190*_xscale/100);
        set("y1", 130*_yscale/100);
        set("x2", 360*_xscale/100);
        set("y2", 270*_yscale/100);
        startDrag(image, false, x1, y1, x2, y2);
    };
    movieClip.onMouseUp = function () {
        stopDrag();
        delete x1;
        delete x2;
        delete y1;
        delete y2;
    };
}

pan(image);

code:

---

function pan(movieClip) {
    movieClip.onMouseDown = function() {
        set("x2", this._width/2);
        set("y2", this._height/2);
        set("x1", x2-(this._width-550));
        set("y1", y2-(this._height-400));
        startDrag(image, false, x1, y1, x2, y2);
    };
    movieClip.onMouseUp = function() {
        stopDrag();
        delete x1;
        delete y1;
        delete x2;
        delete y2;
    };
}
pan(image);
