The goog.graphics.ext.coordinates Namespace
.computeValue(coord, size, scale)
Returns the value of the given expression in the given context.
Should be treated as package scope.
coord {string|number}
- The coordinate to convert.
size {number}
- The size of the parent element.
scale {number}
- The ratio of pixels to units.
- returns {
number}
- The number of coordinate space units that corresponds to
this coordinate.
.getValue(coord, forMaximum, containerSize, scale, opt_cache)
Converts the given coordinate to a number value in units.
Should be treated as package scope.
coord {string|number}
- The coordinate to retrieve the value for.
forMaximum {boolean|undefined}
- Whether we are computing the largest
value this coordinate would be in a parent of no size. The container
size in this case should be set to the size of the current element.
containerSize {number}
- The unit value of the size of the container of
this element. Should be set to the minimum width of this element if
forMaximum is true.
scale {number}
- The ratio of pixels to units.
opt_cache {Object=}
- Optional (but highly recommend) object to store
cached computations in. The calling class should manage clearing out
the cache when the scale or containerSize changes.
- returns {
number}
- The correct number of coordinate space units.
.isSpecial(coord)
Determines if the given coordinate is special - i.e. not just a number.
coord {string|number|null}
- The coordinate to test.
- returns {
boolean}
- Whether the coordinate is special.
