allowTouchScrolling
allowTouchScrolling:
boolean
Indicates whether the browser can be scrolled when using a touchscreen and dragging on the canvas It gives PRIORITY to DOM scrolling, it doesn’t make it always possible. If is true, when using a touch event on the canvas, the canvas will scroll if scroll is possible. If we are in drawing mode or if we are selecting an object the canvas preventDefault and so it won’t scroll

Background image of canvas instance. since 2.4.0 image caching is active, please when putting an image as background, add to the canvas property a reference to the canvas it is on. Otherwise the image cannot detect the zoom vale. As an alternative you can disable image objectCaching

backgroundVpt:
boolean
if set to false background image is not affected by viewport transform

a fabricObject that, without stroke define a clipping area with their shape. filled in black the clipPath object gets used when the canvas has rendered, and the context is placed in the top left corner of the canvas. clipPath will clip away controls, if you do not want this to happen use controlsAboveOverlay = true

Default

renderOnAddRemove
renderOnAddRemove:
boolean
Indicates whether StaticCanvas#add, StaticCanvas#insertAt and StaticCanvas#remove, StaticCanvas#moveTo, StaticCanvas#clear and many more, should also re-render canvas. Disabling this option will not give a performance boost when adding/removing a lot of objects to/from canvas at once since the renders are queued and executed one per frame. Disabling is suggested anyway and managing the renders of the app manually is not a big effort ( canvas.requestRenderAll() ) Left default to true to do not break documentation and old app, fiddles.

CanvasRenderingOptions.renderOnAddRemove
Defined in

skipOffscreen
skipOffscreen:
boolean
Based on vptCoords and object.aCoords, skip rendering of objects that are not included in current viewport. May greatly help in applications with crowded canvas and use of zoom/pan If One of the corner of the bounding box of the object is on the canvas the objects get rendered.
