    <p>There is a method for retrieving the bounding box of an element with and without transformation.</p> <p>With transformation:</p> <pre><code>var bbox = image.getBBox(), width = bbox.width, height = bbox.height; </code></pre> <p>Without transformation:</p> <pre><code>var bbox = image.getBBoxWOTransform(), width = bbox.width, height = bbox.height; </code></pre> <hr> <p>You can extend Raphael.el with helper methods (if you are careful) that provide the width and height directly if this helps you. You could just use the bounding box method and return the portion that you're interested in, but to be a bit more efficient I have calculated only the requested property using the matrix property on the elements and the position/width/height from attributes.</p> <pre><code>(function (r) { function getX() { var posX = this.attr("x") || 0, posY = this.attr("y") || 0; return this.matrix.x(posX, posY); } function getY() { var posX = this.attr("x") || 0, posY = this.attr("y") || 0; return this.matrix.y(posX, posY); } function getWidth() { var posX = this.attr("x") || 0, posY = this.attr("y") || 0, maxX = posX + (this.attr("width") || 0), maxY = posY + (this.attr("height") || 0), m = this.matrix, x = [ m.x(posX, posY), m.x(maxX, posY), m.x(maxX, maxY), m.x(posX, maxY) ]; return Math.max.apply(Math, x) - Math.min.apply(Math, x); } function getHeight() { var posX = this.attr("x") || 0, posY = this.attr("y") || 0, maxX = posX + (this.attr("width") || 0), maxY = posY + (this.attr("height") || 0), m = this.matrix, y = [ m.y(posX, posY), m.y(maxX, posY), m.y(maxX, maxY), m.y(posX, maxY) ]; return Math.max.apply(Math, y) - Math.min.apply(Math, y); } r.getX = getX; r.getY = getY; r.getWidth = getWidth; r.getHeight = getHeight; }(Raphael.el)) </code></pre> <p>With usage:</p> <pre><code>var x = image.getX(); var y = image.getY(); var width = image.getWidth(); var height = image.getHeight(); </code></pre> <p>Just include the script after you include Raphael. Note that it only works for elements with a width, height, x and y attributes, which is suitable for images. Raphael actually computes the bounding box from the path data, which transforms all of the points in the path and gets the min/max x/y values after transforming them.</p>

    1. COI was afraid you'd mention `getBBox` :( In other words, I was afraid there's no direct object method to retrieve the width and height and that I'd have to compute them "manually"

    2. COWhy is this a problem? Can you explain a little more what you're trying to do and why the computed bounding box is a problem? Of course there is no value which actually contains the values, it has to be computed. In raw svg you can get only get the bounding box as an object as well. Either way you can't avoid having to call a function, and it's trivial to write a helper to give you just the width and just the height as numbers.

    3. COComputing the size of the image after it's been rotated and scaled isn't a problem, but rather a nuisance. I've already computed the values of the width and height for the image based on the bbox width+height and the rotation angle (some ugly expressions), but wanted to know if there's a way to get those results directly.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
