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。
因为并没有MonkeyRunner的项目背景，所以这里更多的是描述各个API是怎么一回事，而不是描述在什么场景下需要用到。也就是说是去回答What，而不是How。
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 |
|
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：
viewer = device.getHierarchyViewer() note = viewer.findViewById('id/title') text = viewer.getText(note) print text.encode('utf-8') point = viewer.getAbsoluteCenterOfView(note) x = point.x y = point.y img = device.takeSnapshot() pixelTuple = img.getRawPixel(x,y) pixelInt = img.getRawPixelInt(x,y) print "Pixel in tuple:",pixelTuple print "Pixel in int:", pixelInt输出：
