c# - Setting options to images in Magick .NET collection -

-

I'm trying to reduce the file size of GIF animation, I've read how to do it . Another thread has suggested to reduce the quality, add compression and make the photo a little blurred, which I am trying to do: 

 using  (MagickImageCollection col = New MagickImageCollection (@ "C: / PathToGif")) {for (int i = 0; i & lt; col.Qount; i ++) {Cole [i] .Quality = 85; Colonel [I] Compression Method = Compression Method LZW; Col [i] .Strip (); } Col.Write (@ "C: / path / to / outpath"); }   
 Although the code is running but setting can not be ignored, while setting  AnimationDelay  works the same way. I confirm this by checking the quality of the output and the file size, it seems that when I do not use any settings, even setting  quality  to 20, Find similar results.  
 I also tried to use QuantizeSettings , where I crossed the value of  255  in the  color  property . That was to lock my application while using 50% of the CPU. (I gave the application about 5 minutes before closing firmly)  
 My application is about one in 950 kb. GIF processes and changes it to 5.3 MB, which is unacceptable. (Disclaimer: I add approximately 20 + - frame to GIF and drag an overlay on it).  
 There may be some experience with Magic. The Net Library tells me whether I am doing something wrong and tell me in the right direction to do this? I was unable to find another way to implement these settings.   
 
 
 GIF codeer does not use quality settings and compression method always compression method. LZW will be. If you want to customize the output file, then you should do the following:  
 using  (MagickImageCollectioncol = New MagickImageCollection (@ "C: / PathToGif")) {col.Coalesce (); AddOtherImages (col); Col.Optimize (); Col.OptimizeTransparency (); Col.Write (@ "C: / path / to / output"); }   
 Make sure you upgrade to the latest version, optimized / optimized transparency methods were past in previous versions.

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
