我使用Kineticjs命中区域,如建议:http://www.html5canvastutorials.com/kineticjs/html5-canvas-pixel-detection-with-kineticjs/
My Image has a stroke:
var lion = new Kinetic.Image({
image: images.lion,
x: 280,
y: 30,
stroke: "red"
});
当没有使用命中区域时,图像有一个笔画,但是当我使用以下内容时,我没有看到任何笔画。
// in order to ignore transparent pixels in an image when detecting
// events, we first need to cache the image
lion.cache();
// next, we need to redraw the hit graph using the cached image
lion.drawHitFromCache();
// finally, we need to redraw the layer hit graph
layer.drawHit();
当我使用命中区域时,我如何获得图像可见的笔画?
如果你想要边框,你可以设置drawBorder属性为true:
lion.cache({
drawBorder: true
});
干杯!
