Useful functions that you can call, e.g. when having a reference to this component:
getSaveData()
returns the drawing's save-data as stringified JSONloadSaveData(saveData: String, immediate: Boolean)
loads a previously saved drawing using the saveData string, as well as an optional boolean flag to load it immediately, instead of live-drawing it.clear()
clears the canvas completelyundo()
removes the latest change to the drawing. This includes everything drawn since the last MouseDown event.drawLine(line)
to draw a line. This can be useful if you want to automate drawing. The line parameter is an object of the following form:const line = {
color: this.props.brushColor,
size: this.props.brushSize,
startX: this.x,
startY: this.y,
endX: newX,
endY: newY
};
This repo was kickstarted by nwb's awesome react-component starter.
You just need to clone it, yarn it & start it!
If you want to save large strings, like the stringified JSON of a drawing, I recommend you to use pieroxy/lz-string for compression. It's LZ compression will bring down your long strings to only ~10% of it's original size.
