                suckerArea: [],
                isSucking: false
            }
        },
        methods: {
            changeColor(color) {
                const {rgba: {r, g, b, a}} = color
                this.color = `rgba(${r, g, b, a})`
            },
            openSucker(isOpen) {
                if (isOpen) {
                    // ... canvas be created
                    // this.suckerCanvas = canvas
                    // this.suckerArea = [x1, y1, x2, y2]
                } else {
                    // this.suckerCanvas && this.suckerCanvas.remove
                }
            }
        }
    }
</script>

Options

name type default desc
color String #000000 rgba or hex
colors-default Array ['#000000', '#FFFFFF', '#FF1900', '#F47365', '#FFB243', '#FFE623', '#6EFF2A', '#1BC7B1', '#00BEFF', '#2E81FF', '#5D61FF', '#FF89CF', '#FC3CAD', '#BF3DCE', '#8E00A7', 'rgba(0,0,0,0)'] like ['#ff00ff', '#0f0f0f', ...]
colors-history-key String vue-colorpicker-history
sucker-hide Boolean true true or false
sucker-canvas HTMLCanvasElement null like document.createElement('canvas')
sucker-area Array [] like [x1, y1, x2, y2]

color is one-way data flow, so you can't use v-model. why? because you'll listen change event do more things, so i think it's not necessary here.

Events

name type emit args desc
changeColor Function color { rgba: {}, hsv: {}}
openSucker Function isOpen true or false

if you want use sucker, then openSucker, sucker-hide, sucker-canvas, sucker-area is necessary.
