Class Detail
JXG.ForeignObject(board, coordinates, attributes, url, size)
Construct and handle SVG foreignObjects.
- Parameters:
- {string|JXG.Board} board
- The board the new foreignObject is drawn on.
- {Array} coordinates
- An array with the user coordinates of the foreignObject.
- {Object} attributes
- An object containing visual and - optionally - a name and an id.
- {string|function} url
- An URL string or a function returning an URL string.
- {Array} size
- Array containing width and height of the foreignObject in user coordinates.
Field Detail
content
'href' of the foreignObject.
{Array}
size
Array of length two containing [width, height] of the foreignObject in pixel.
Method Detail
{number}
H()
Returns the height of the foreignObject in user coordinates.
- Returns:
- {number} height of the image in user coordinates
{Boolean}
hasPoint(x, y)
Checks whether (x,y) is over or near the image;
- Parameters:
- {Number} x
- Coordinate in x direction, screen coordinates.
- {Number} y
- Coordinate in y direction, screen coordinates.
- Returns:
- {Boolean} True if (x,y) is over the image, False otherwise.
{JXG.ForeignObject}
setSize(width, height)
Set the width and height of the foreignObject. After setting a new size,
board.update() or foreignobject.fullUpdate()
has to be called to make the change visible.
- Parameters:
- {numbe|function|string} width
- Number, function or string that determines the new width of the foreignObject
- {number|function|string} height
- Number, function or string that determines the new height of the foreignObject
- Returns:
- {JXG.ForeignObject} A reference to the element
<private>
{JXG.ForeignObject}
update(fromParent)
Recalculate the coordinates of lower left corner and the width and height.
- Parameters:
- fromParent
- Returns:
- {JXG.ForeignObject} A reference to the element
<private>
updateRenderer()
Send an update request to the renderer.
<private>
{JXG.ForeignObject}
updateSize()
Updates the internal arrays containing size of the foreignObject.
- Returns:
- {JXG.ForeignObject} A reference to the element
<private>
{JXG.ForeignObject}
updateSpan()
Update the anchor point of the foreignObject, i.e. the lower left corner
and the two vectors which span the rectangle.
- Returns:
- {JXG.ForeignObject} A reference to the element
{number}
W()
Returns the width of the foreignObject in user coordinates.
- Returns:
- {number} width of the image in user coordinates
