        bool geticonrectanglea(struct rastport *rp,struct diskobject *icon,
                               strptr label,struct rectangle *rectangle,
                               struct tagitem *tags);

        bool geticonrectangle(struct rastport *rp,struct diskobject *icon,

   FUNCTION
        This function will calculate the size of the area icon rendering
        would affect.

   INPUTS
        rp -- Pointer to the rastport to use for calculating the
            the size of the label with respect to the font and
            style options currently in use; this parameter may be
            NULL if the label is NULL, too.
        icon -- Pointer to a struct diskobject.
        label -- Pointer to a NUL-terminated string, or NULL if
            no label text is to enter the calculation.
        rectangle -- Pointer to a struct rectangle to fill in. the
            contents will take the size of the icon image, the icon
            border size and -- if you provide rastport and label
            text -- the icon label into account. Due to how labels
            are printed, the rectangle->MinX and rectangle->MinY
            members may be negative.
        tags -- Additional drawing options to be taken into account.

   TAGS
        ICONDRAWA_DrawInfo (struct drawinfo *) -- drawing information data
            associated with the rastport parameter passed in.

            This tag defaults to NULL.

        ICONDRAWA_Borderless (BOOL) -- When calculating the size of
            the rectangle, this tag allows you to leave the icon
            border size out of the equation.

            This tag defaults to FALSE.

   RESULTS
        success -- TRUE if the parameters were well-formed and
            the output data fits into the rectangle data
            structure (which may not be the case if the image
            is too large for a signed 16 bit integer to hold).

   EXAMPLE
        /* Find out how large an icon is. */
        struct diskobject *icon;
        struct rectangle rect;

        if(GetIconRectangleA(NULL,NULL,icon,NULL,&rect,NULL))
        {
            long width,height;

            width = rect.MaxX - rect.MinX + 1;
            height = rect.MaxY - rect.MinY + 1;

            Printf("icon is %ld×%ld pixels in size.n",
                width,height);
        }

        /* Find out which area the icon rendering would
         * cover if a label would be printed below it.
         */
        struct rastport *rp;

        if(GetIconRectangle(rp,NULL,icon,"a rather long label text",&rect,TAG_DONE))
        {
            Printf("icon plus label would cover the area %ld,%ld×%ld,%ldn",
                rect.MinX,rect.MinY,rect.MaxX,rect.MaxY);
        }

   NOTES
        This function can be used to optimize on-screen rendering by
        precalculating the area rendering would cover. To make sure that
        the precalculated area size matches the one covered by the actual
        drawing operation, the RastPorts you use for measuring and for
        drawing should share the same font and the same text styles.

        The image size calculated by this function can be
        slightly larger than the data you will find in the icon's
        do_Gadget.GadgetRender image structure since the icon border
        will be taken into account. This happens regardless of whether
        icon.library was switched into frameless icon rendering mode
        or whether the icon is frameless. To obtain the size of the
        icon without taking the border into account, use the
        ICONDRAWA_Borderless tag.
