QUESTION
I'm using drawImage
function with the same image but i got diffrent results when the source is img element vs when the source is canvas(with the same size as original image).
this is the code
...ANSWER
Answered 2021-Jun-09 at 12:11The culprit is imageSmothingQuality = "high"
, I already faced it before, even with ImageBitmaps.
Different sources will get different results with their algo, even two JPEG will have very different quality depending on the compression of the image.
You did well opening that issue.
Note that in my tests then I had the best looking results with imageSmothingQuality = "medium"
, which also doesn't suffer from this bug.

QUESTION
I have a class like this:
...ANSWER
Answered 2021-Apr-18 at 05:52Storing a pointer to ComplexClass
would work, but using a raw pointer would be unwise. Use std::shared_ptr
.
Alternatively, you could delete the copy constructor & assignment, and then store Bla
in shared_ptr
s when you do need assignments.
And instead of deleteing the copy operations, you can:
- Make them private, and add a member function with a long scary name that performs them, in case you need them.
- Delete just the copy assignment, and make the copy constructor
explicit
. Thena = b;
wouldn't compile, buta = Bla(b);
still would.
QUESTION
I have a program that takes encoded commands from a host through a socket, using a thread that continuously listens to the socket and starts new threads to handle each command. A command is either a bad message which can be ignored, or it starts with 3 letter indicating what to do, then a %, then content in json format and ends with \0. Content range in length from 12 to 100000+ chars.
...ANSWER
Answered 2021-Apr-06 at 05:31Having multiple threads simultaneously use the same TCP socket is possible in that most operating systems support it (i.e. you won't crash), but it's not useful because it's unpredictable which thread will end up receiving which bytes of data from the socket (or conversely, which thread will end up sending which bytes of data to the socket when) -- in either case your TCP data will end up getting randomly send to your various threads, which is a big problem if your messages are ever longer than one byte long.
What you can do, OTOH, is have one thread that is dedicated to only reading from the TCP socket, and when it has read in a full message, it hands that message over to one of the other threads (using a mutex-protected FIFO queue and a condition-variable, or similar) for processing. If the processing-thread later wants to send data back to the TCP socket, it would hand the data back to the network-thread via another FIFO queue, and then the network thread would take care of pulling the data out of the FIFO and writing it out to the TCP socket. In that design, because only one thread has access to the TCP socket, you can guarantee that messages boundaries are respected and messages do not get mixed up with each other.
Note that in order to have the network thread handle both reading and writing (and responding to incoming messages on its FIFO queue) in a timely manner, you may want to have it use non-blocking I/O and event-loop that blocks only inside select()
.

QUESTION
Lets make obscure question simple...
We have a solution which consists of many projects and some of them have set Custom build events using 3rd party stuff for some dark magic compilation and looks similar like this:
...ANSWER
Answered 2021-Mar-23 at 09:00The real problem is that your real project is always rebuild due to the metadata Outputs
.
The special point is that you should make sure the validity and legitimacy of the value of Outputs
.
The problem is under %(RelativeDir)
of %(RelativeDir)%(Outputs)
. When you add it, the outputs
has an illegal folder structure rather than a file which makes the outputs
always find the missing illegal folder structure so that causes the project always rebuild.
Let me describe it in detail,
when msbuild reads outputs
proeperty, when it reads till %(RelativeDir)%(Filename).cpp;%(RelativeDir)%(Filename).h;%(RelativeDir)
, the value of Outputs
is this:
