问题 This question is about printing ALL content (including off screen content) of WKWebView. Currently (still, as of iOS 10.2 or OSX 10.12) there is NO working solution and none of the supposed solutions on Stackoverflow work. Only provide an answer here if you have verified for yourself that you can print OFF SCREEN CONTENT, and if you did then provide the working example code. I'm trying to print ALL the content of a WKWebView or WebView on OSX 10.10 or above (Currently running on 10.11.2). For

问题 I want to print the docstring of a python function from inside the function itself. for eg. def my_function(self): """Doc string for my function.""" # print the Docstring here. At the moment I am doing this directly after my_function has been defined. print my_function.__doc__ But would rather let the function do this itself. I have tried calling print self.__doc__ print self.my_function.__doc__ and print this.__doc__ inside my_function but this did not work. 回答1: def my_func(): """Docstring

问题 I want to write a application in C++ or C# that will behave as a printer driver when installed. It will be available in the drop down list in Print dialog but instead of printing it will call into my code. I think there may be some interfaces that Windows provide to write printer drivers. 回答1: Windows provides loads of interfaces. Do you know what sort of a printer driver you want to write? At present, Windows supports three flavors of printer drivers -- PostScript, Unidrv and XPSDrv (the

问题 I would like to add wireless printing to my android 2.2 application which is targeted for the Galaxy tablet. I see that the internet browser has a print option so I am assuming that an activity hook must exist, and I was hoping that someone has figured this out. I have found a possibility using the PrinterShare application from Mobile Dynamix, but my preference would be to no require a 3rd party. Here is the code example that they provide, just for reference. Intent i = new Intent(Intent

问题 this question seems posted at many places over the interwebs and SO, but I could not find a satisfactory answer :( How can I convert a RGB value to a CMYK value using an ICC profile? The closest answer I have is there, where it explains how to convert from CMYK to RGB but not the other way around, which is what I need. (http://stackoverflow.com/questions/4920482/cmyk-to-rgb-formula-of-photoshop/5076731#5076731) float[] colorValues = new float[4]; colorValues[0] = c / 255f; colorValues[1] = m

问题 Note: This question is for informational purposes only. I am interested to see how deep into Python's internals it is possible to go with this.

For example, consider the function: def print_something(): print('This cat was scared.') Now, when print is run, then the output to the terminal should display: This

问题 Why do I get the wrong values when I print an int using printf("%f\n", myNumber) ? I don't understand why it prints fine with %d , but not with %f . Shouldn't it just add extra zeros? int a = 1; int b = 10; int c = 100; int d = 1000; int e = 10000; printf("%d %d %d %d %d\n", a, b, c, d, e); //prints fine printf("%f %f %f %f %f\n", a, b, c, d, e); //prints weird stuff 回答1: well of course it prints the "weird" stuff. You are passing in int s, but telling printf you passed in float s. Since
