3/8/2024 0 Comments Fabric js load png black![]() There are 4 properties on canvas that control its presentation - "selectionColor", "selectionBorderColor", "selectionLineWidth", and "selectionDashArray". Now, what if you don't want to disable selection, but instead want to change its appearance? No problem. Just set it to false and an object loses its interactivity. If you only need to make certain objects unselectable, you can change "selectable" property of objects. This prevents selection on absolutely everything displayed on canvas. You can disable selection of objects on canvas by setting "selection" property of canvas to false. You can also change their appearance by tweaking some of the customization properties "cornerDashArray", "borderDashArray", "borderColor", "transparentCorners" "cornerColor", "cornerStrokeColor", "cornerStyle", "selectionBackgroundColor", "padding" and "cornerSize" properties. Just set them to false and objects instantly render "naked". You can control objects' borders and corners visibility via "hasControls" and "hasBorders" properties. You can combine them together in any way. Simiarly, lockRotation prevents rotation and lockScalingX/ lockScalingY - scaling. You can still move it in vertical plane though. So setting object.lockMovementX to true prevents object from being moved horizontally. "lockMovementX", "lockMovementY", "lockRotation", "lockScalingX", "lockScalingY" are properties that lock corresponding object actions. Locking objectsĮvery object on canvas can be locked in few ways. You can tweak dozens of various parameters on canvas or canvas objects, in order to make things behave exactly the way you want. One of the amazing things about Fabric is how customizable it is. Also custom brush patterns, and an option to extend with your own, similar to Fabric image filters.Įrasing is another cool available feature that plays nicely with free drawing. In the near future, we are planning to add more options for free drawing - various versions of a brush (e.g. freeDrawingBrush.width is a number in pixels, and represents brush thickness. lor can be any regular color value and represents the color of a brush. Both are available on Fabric canvas instances through freeDrawingBrush instance. There are also 2 properties available to customize free drawing - lor and freeDrawingBrush.width. And since they're good old fabric.Path objects, you can modify them any way you want - move, rotate, scale, etc. If, at any moment, you set isDrawingMode back to false, you'll end up with all of the created path objects still present on canvas. But as soon as you perform any movement, followed by a "mouseup" event, Fabric fires "path:created" event and actually transforms just-drawn shape into a real fabric.Path instance! You can paint as many times on canvas as you wish, while isDrawingMode is true. ![]() This immediately makes any further clicks and movements on canvas get interpreted as a pencil/brush. And of course Fabric takes care of this for us.Ī free drawing mode is enabled simply by setting isDrawingMode property of Fabric canvas to true. If there's anything really shines at, it's that it has an excellent support for free drawing! Since canvas is simply a 2D bitmap - a paper to paint on - performing free drawing is very natural. But there's still couple of very interesting and useful things to discuss! Free drawing ![]() It's better to explain with code, let's say you downloaded this texture and placed it in the public folder of your site, to get the color map from it you could do: const colorMap = useLoader ( TextureLoader, 'PavingStones092_1K_Color.We've covered so many topics in the previous series from basic object manipulations to animations, events, filters, groups, and subclasses. ![]() To load the textures we will use the TextureLoader from three.js in combination with useLoader that will allow us to pass the location of the texture and get the map back. All textures used in this chapter were downloaded from cc0textures.
