|
* The 'rect' element defines a rectangle which is axis-aligned with the current user coordinate system. Rounded |
|
9
|
|
|
* rectangles can be achieved by setting appropriate values for attributes 'rx' and 'ry'. |

|
* @property float rx For rounded rectangles, the x-axis radius of the ellipse used to round off the corners of the |
|
13
|
|
|
* rectangle. A negative value is an error |
|
14
|
|
|
* @property float ry For rounded rectangles, the y-axis radius of the ellipse used to round off the corners of the |
|
15
|
|
|
* rectangle. A negative value is an error |
|
16
|
|
|
* @property float x The x-axis coordinate of the side of the rectangle which has the smaller x-axis coordinate value |
|
17
|
|
|
* in the current user coordinate system. If the attribute is not specified, the effect is as if a value of |

It seems like the type of the argument is not accepted by the function/method which you are calling.
In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.
We suggest to add an explicit type cast like in the following example:
