This is a beautiful multi-level drop-down menu landscaping, can be a perfect substitute for "select" to achieve the effect of the Drop-down menu. and support multi-level menu, there is load waiting effect, there are hierarchical classification display.
Copy Code code as follows:
body {font-size:62.5%; margin:0; padding:0;}
#menuLog {font-size:1.4em; margin:20px;}
. hidden {position:absolute; top:0; left:-9999px; width:1px; height:1px; overflow:hidden;}

~/.tmuxinator/project_a.yml . To implement the configuration required for project A, you need to project_a.yml update the content to:Name:project_aroot: Once the above configuration has been added to the Yaml file of Project A, only the following command can be run to start the Tmux session.$ tmuxinator Start project_aOf course, if you want, you can also use the alias of the Tmuxinator command:$ MUX Start project_aIt's done. Now, whenever you want to get into Project A's coding, you just need
(just manage your own bash);
Foreground: You can control the work of the environment called foreground (foreground) with the placing of commands;
Background: You can run your own work, you cannot use [ctrl]+c to terminate him, you can use BG/FG to call the job;
The "Running" program in the background cannot wait for Terminal/shell input
Then let's actually manage the work!
Management of Job ControlAs mentioned earlier,Bash can
ASP. after uploading an image, add a watermark. for example, the URL. the text is white. however, when the background is white, the watermark cannot be seen at all. search for materials and find a method to draw text shadow. I found several, finally found a foreigner's article, and. net comes with the same statement in the documentation. instead, draw 2-5 gray texts with different alpha values as shadows .. then, draw the text of the normal color .... khan !!!!!!!!!!!!!!!!!! 111 there is no way,
Kill-Stop 1234 pause the process.If you want to restore it to the background, use kill-cont 1234 (many programs running on the foreground do not work)To restore the process to the foreground, run the jobs command on the terminal that was running the process to query the paused process.Then use FG [job number] to restore the process to the foreground.If jobs only queries one process, only FG is required.For
in the background) pause or run. It should be noted that when a job that is placed in the background wants to run, it must not be able to interact with the user. For example, vim cannot run (running) in the background! He won't run because you didn't input the data! In addition, you cannot use [ctrl] + c to terminate the work in the background 』!
In short, the following restrictions must be noted for bash job control:
The program triggered by these jobs must come from your shell subroutine (o

If jobs only queries a single process, only
that when a job that is put into the background wants to run, he must not be able to interact with the user. For example, VIM is absolutely impossible to run in the background (running)! Because you didn't enter the data, he wouldn't run! and the job of putting the background is not to use [ctrl]+c to terminate!] In summary, the restrictions that you must notice to perform the job control for bash are:
The programs triggered by these jobs must come from your shell's subroutines (just m

ILC is weighted by six image eigenvalues and [2], respectively:
Laplace 0 Point value (Laplacian zero-crossing)
Gradient measure (Gradient magnitude)
Gradient direction value (Gradient direction)
Boundary pixel grayscale value (edge pixel value)
Internal pixel grayscale value (Inside pixel value)
External pixel grayscale value (Outside pixel value)
In the paper [1], only the previous three decisions.Set l(p,q) the value that represents ILC, p for pixels, and Q
"assignment"). The problem is that, from the compiler's point of view, if branch A, B, and C are not running, then rate may not be assigned. So in double res = rate. Attempting to read the value of rate is illegal.Some students say that to solve a problem, you can assign a value to it when you define it: double rate = 0.This will prevent the compiler from error, but it may not be the best solution. Suppose A, B, and C three branches can include the entire condition space . Then I think the code
