MonkeyImageAPI实践全记录-创新互联
1. 背景
鉴于网上使用MonkeyImage的实例除了方法sameAs外很难找到,所以本人把实践各个API的过程记录下来然自己有更感性的认识,也为往后的工作打下更好的基础。同时也和上一篇文章《MonkeyDevcie API 实践全记录》起到相互呼应的作用。

首先我们先看下官方给出的MonkeyImage的API描述,对比我现在反编译的最新的源码是一致的:
Return Type | Methods | Comment |
string | convertToBytes (string format) Converts the current image to a particular format and returns it as a string that you can then access as an iterable of binary bytes. | |
tuple | getRawPixel (integer x, integer y) Returns the single pixel at the image location (x,y), as an a tuple of integer, in the form (a,r,g,b). | |
integer | getRawPixelInt (integer x, integer y) Returns the single pixel at the image location (x,y), as a 32-bit integer. | |
| getSubImage (tuple rect) Creates a new | |
boolean | sameAs ( Compares this | |
void | writeToFile (string path, string format) Writes the current image to the file specified by |
2. String convertToBytes(string format)
2.1 示例
img = device.takeSnapshot() png1 = img.convertToBytes() png2 = img.convertToBytes() bmp = img.convertToBytes('bmp') jpg = img.convertToBytes('JPG') gif = img.convertToBytes('gif') raw = img.convertToBytes('raw') invalid = img.convertToBytes('xxx') #is the 2 pngs equal? print "Two png is equal in bytes:",png1 == png2 #is the png equals to bmp? print "png and bmp is equal in bytes:", png1 == bmp #is the jpg eqals to the raw? print "jpg and bmp is equals in bytes:",jpg == bmp #is the jpg eqals to the xxx? print "jpg is a valid argument:",jpg != invalid #is the gif eqals to the xxx? print "gif is a valid argument:",gif != invalid #is the bmp eqals to the xxx? print "bmp is a valid argument:",bmp != invalid #is the raw equas to xxxx? aims at checking whether argument 'raw' is invalid like 'xxx' print 'raw is a valid argument:',raw != invalid #would invalid argument drop to png by default? print 'Would invalid argument drop to png by default:',png1 == invalid输出:
2.2 分析
除了默认的png,常用格式jpg,gif都支持,但bmp格式无效,至于还支持什么其他格式,尝试跟踪了下代码,没有找到想要的结果另外有需要云服务器可以了解下创新互联scvps.cn,海内外云服务器15元起步,三天无理由+7*72小时售后在线,公司持有idc许可证,提供“云服务器、裸金属服务器、高防服务器、香港服务器、美国服务器、虚拟主机、免备案服务器”等云主机租用服务以及企业上云的综合解决方案,具有“安全稳定、简单易用、服务可用性高、性价比高”等特点与优势,专为企业上云打造定制,能够满足用户丰富、多元化的应用场景需求。
