Answer : If a function has nothing specific to return, it is often customary to return one of the input parameters (the one that is seen as the primary one). Doing this allows you to use "chained" function calls in expressions. For example, you can do char buffer[1024]; strcat(strcpy(buffer, "Hello"), " World"); specifically because strcpy returns the original dst value as its result. Basically, when designing such a function, you might want to choose the most appropriate parameter for "chaining" and return it as the result (again, if you have noting else to return, i.e. if otherwise your function would return void ). Some people like it, some people don't. It is a matter of personal preference. C standard library often supports this technique, memcpy being another example. A possible use case might be something along the lines of char *clone_buffer(const char *buffer, size_t size) { return memcpy(new char[size], buffer, siz

Answer : How to copy Mysql database from one Computer to another / backup database using mysqldump We can transfer a MySQL database from one PC to another PC using mysqldump command. We have to create dump file of database to transfer database from one PC to another PC. MySQL database is not portable database i.e. we cannot transfer it from one PC to another PC by copying and pasting it. We can use following method to transfer database. Creating a dumpfile from database/ Taking backup of MySQL database: Open command prompt. Execute following commands to change directory >c: “press enter” >cd program files/MySQL/MySQL Server 5.1/ bin “press enter” >mysqldump -u root -p database_name > database_name.sql “press enter” Enter password: password of MySQL Copy sql file and paste it in PC where you want to transfer database. 2. Dumping sql file into database:- - Open MySQL command line client command prompt. - Execute following command to create database

Example 1: flutter move container to top center Center ( child : Container ( alignment : Alignment ( 0.0 , - 1.0 ) , ) , ) ; Example 2: align bottom flutter // Use Align if have only one child, if have multiple: return Column ( crossAxisAlignment : CrossAxisAlignment . center , mainAxisSize : MainAxisSize . max , mainAxisAlignment : MainAxisAlignment . end , children : < Widget > [ //your elements here ] , ) ;

Answer : If with "world coordinates" you mean "object coordinates", you have to get the inverse transformation of the result given by the pnp algorithm. There is a trick to invert transformation matrices that allows you to save the inversion operation, which is usually expensive, and that explains the code in Python. Given a transformation [R|t] , we have that inv([R|t]) = [R'|-R'*t] , where R' is the transpose of R . So, you can code (not tested): cv::Mat rvec, tvec; solvePnP(..., rvec, tvec, ...); // rvec is 3x1, tvec is 3x1 cv::Mat R; cv::Rodrigues(rvec, R); // R is 3x3 R = R.t(); // rotation of inverse tvec = -R * tvec; // translation of inverse cv::Mat T = cv::Mat::eye(4, 4, R.type()); // T is 4x4 T( cv::Range(0,3), cv::Range(0,3) ) = R * 1; // copies R into T T( cv::Range(0,3), cv::Range(3,4) ) = tvec * 1; // copies tvec into T // T is a 4x4 matrix with the pose of the camera in the object frame Update: Later, to use T with OpenGL

Answer : You can use one commandline with two commands ( gs , convert ) connected through a pipe, if the first command can write its output to stdout, and if the second one can read its input from stdin. Luckily, gs can write to stdout ( ... -o %stdout ... ). Luckily, convert can read from stdin ( convert -background transparent - output.png ). Problem solved: GS used for alpha channel handling a special image, convert used for creating transparent background, pipe used to avoid writing out a temp file on disk. Complete solution: gs -sDEVICE=pngalpha \ -o %stdout \ -r144 cover.pdf \ | \ convert \ -background transparent \ - \ cover.png Update If you want to have a separate PNG per PDF page, you can use the %d syntax: gs -sDEVICE=pngalpha -o file-%03d.png -r144 cover.pdf This will create PNG files named page-000.png , page-001.png , ... (Note that the %d -counting is zero

Answer : Like this demo css table{ width:100%; } You need to use: table{ width:100%; table-layout: fixed; overflow-wrap: break-word; } Demo I have a very well working solution for tables of max-width: 100% . Just use word-break: break-all; for the table cells (except heading cells) to break all long text into several lines: <!DOCTYPE html> <html> <head> <style> table { max-width: 100%; } table td { word-break: break-all; } </style> </head> <body> <table border="1"> <tr> <th><strong>Input</strong></th> <th><strong>Output</strong></th> </tr> <tr> <td>some text</td> <td>12b6459fc6b4cabb4b1990be1a78e4dc5fa79c3a0fe9aa9f0386d673cfb762171a4aaa363b8dac4c33e0ad23e4830888</td> </tr> </table> </body> </html> This will render like this (when the screen width is
