move to Canvas
Background color of canvas instance.
Optional backgroundBackground 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
if set to false background image is not affected by viewport transform
1.6.3
we should really find a different way to do this
Optional clipa 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
Indicates whether object controls (borders/controls) are rendered above overlay image
move to Canvas
When true, canvas is scaled by devicePixelRatio for better rendering on retina screens
Height in virtual/logical pixels of the canvas. The canvas can be taller than width if retina scaling is active
Indicates whether this canvas will use image smoothing, this is on by default in browsers
Indicates whether toObject/toDatalessObject should include default values if set to false, takes precedence over the object value.
Overlay color of canvas instance.
1.3.9
Optional overlayOverlay image of canvas instance. since 2.4.0 image caching is active, please when putting an image as overlay, 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
if set to false overlay image is not affected by viewport transform

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.
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.
true
When true, getSvgTransform() will apply the StaticCanvas.viewportTransform to the SVG transformation. When true, a zoomed canvas will then produce zoomed SVG output.
The transformation (a Canvas 2D API transform matrix) which focuses the viewport
Default transform
canvas.viewportTransform = [1, 0, 0, 1, 0, 0];
Scale by 70% and translate toward bottom-right by 50, without skewing
canvas.viewportTransform = [0.7, 0, 0, 0.7, 50, 50];
Width in virtual/logical pixels of the canvas. The canvas can be larger than width if retina scaling is active
Generated using TypeDoc
Indicates whether the browser can be scrolled when using a touchscreen and dragging on the canvas
