Outmimetype properties are assigned values. This technique allows us to get the image's long and wide values and MIME types before loading the image, thus compressing the image as appropriate. As shown in the following code:Bitmapfactory.options Options = new Bitmapfactory.options (); Options.injustdecodebounds = true; Bitmapfactory.decoderesource (Getresources (), r.id.myimage, options); int imageheight = options.outheight; int imagewidth = options.outwidth; String imageType = Options.out

; = Options.outmimetype; To avoid oom anomalies, it's a good idea to check the size of each picture, unless you trust the source of the image so that it doesn't go beyond your program's available memory.Now that the size of the picture is known, we can decide whether to load the entire picture into memory or load a compressed version of the image into memory. Here are a few things we need to consider: Estimate the memory required to load t

environments provide a caller property on a function object to achieve the same effect as Arguments.caller:function Revealcaller () {return revealcaller.caller;} function Start () {return Revealcaller ();} Start () = = = Start; TrueTherefore, you can use this property to get information about the current call stack:function Getcallstack () {var stack = [];for (var f = getcallstack.caller; f; f = F.caller) {Stack.push (f);} return stack;}For a simple call relationship, the above can actually g

property of this parameter to true to prevent the parsing method from allocating memory for bitmap, and the return value is no longer a bitmap object, but null 。 Although the bitmap is null, the Outwidth, Outheight, and Outmimetype properties of the bitmapfactory.options will be assigned. This technique allows us to get the long width and mime type of the picture before loading the picture to compress the picture according to the situation. As shown in the following code: Bitmapfactory.
