复现过程
const img = images.interval(images.read(this.p + "1.png"), 0xffffffff, 0);
images.save(img, this.p + "t.png");
const t = images.read(this.p + "t.png");
const r = images.findImageInRegion(t, img, 1, 1);
总结
只要经过处理的image 放入找图类API中,都会出现这个错误. 如果将图片 保存,再读取后,得到的image则不会出现问题.例如:
const img = images.interval(images.read(this.p + "1.png"), 0xffffffff, 0);
images.save(img, this.p + "t.png");
const t = images.read(this.p + "t.png");
const r = images.findImageInRegion(t, images.fromBytes(images.toBytes(img)), 1, 1);
这样处理后,就不会有任何问题;
