C4 saving part of an image

由 笑着哭i 提交于 2019-12-02 08:27:28
问题 Hei, I went through the example for saving images and afterwards I wanted to save only a part of the screen. I managed to save the part starting at the upper left corner of the image but I actually want to save the center of my screen. The magic to save only a part of an image is setting up the Graphics Context with a certain size, like this: UIGraphicsBeginImageContextWithOptions(CGSizeMake(300, 300), YES, 5.0f); I thought there might be a way to use a CGRect instead of the size, but that

问题 I have made an application. It's a button that shows the time you have pressed it. Every time I "kill" the application, the timer starts at 0 again (naturally). How can I make the application save the time the button is pressed, so when the application is killed, and then you open it, the timer is at that time you stopped.I have red some about how this is done, and I think it has something to do with SharedPreferences. My code: public class MainActivity extends ActionBarActivity { Button

IPython: how to automagically load npz file and assign values to variables?

由 江枫思渺然 提交于 2019-12-02 06:19:01
问题 I'm new to Python and I'm eagerly migrating from MATLAB to IPython as my preferred language for data analysis at the lab. In MATLAB, after a session of data crunching, I would do >>> save('myresults.mat','x','y','z'); and save the results of the variables x, y and z in a file called 'myresults.mat'. Later on, I could simply say: >>> load('myresults'); and MATLAB would load the .mat file AND assign the stored values of the variables to the current workspace. I've recently learned that I can do
