3. GFX: After, next, later
Reminder: What’s new in 1.7
 Input Events
– Canvas support (mostly for Android 2.x devices)
– Targeted shape accessible from event: evt.gfxTarget
 Matrix new APIs:
– matrix.multiplyRectangle
– matrix.isIdentity
 Shape UID
– Shapes identified via a UID: Shape.getUID()
– Internal registry a la dijit: gfx.shape.byId()
– Note: when a shape is not needed anymore: gfx.shape.dispose(shape) !
(improved in 1.8)

4. GFX: After, next, later
What’s planned in 1.8
 Clipping API
– New method: Shape.setClip(clipGeometry)
– Possible geometries:
• Rectangular: {x,y,width,height}
• Ellipse: {cx, cy, rx, ry}
• Polyline: {points}
• Path: {d}
 Destructor API
– Free resources when shape to be destroyed
– Shape.destroy()
– Group.clear(/*Boolean*/ dispose)
 SVG specific extension
– Rendering option:
• shape.addRenderingOption(“shape-rendering”, “optimizeSpeed”);
– Defs
• Shared resources (gradients)
– SVG Filters (?)

5. GFX: After, next, later
What’s planned in 1.8
 Canvas specific extension
– Pixel access API (CanvasPixelArray and ImageData)
– Surface.getImageData()
– Surface.render(context) + aspect.before/after = pre/post-processing
 Shared styles across multiple gfx shapes (?)

6. GFX: After, next, later
What’s next: 2.0+
 1.8 leftover
 Improve serialization
– dojoAttachPoint: : contract between the logic and the graphic
{children:[
{
dojoAttachPoint:‘background’; container.background.connect(…)
shape: { type:’rect’}
}, ...
]}
– Custom properties
 gfx layout
– Prerequesite:
• Text.getBoundingBox()
• Bbox caching
• Bbox changed notification
 WebGL renderer experimentation (which use cases, if any…)
